Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine for reading and scanning an original with a hand scanner for printing, displaying or electric transmission.

More specifically, a hand scanner (consisting of a one-dimensional reading sensor for reading an original,
The main scanning direction is the dimensional direction), and the original is read and scanned in the sub-scanning direction orthogonal to the main scanning direction. At that time, the sub-scanning direction is relative to the vertical direction of the read original. For example, assuming that the orthogonal direction is the normal direction, when scanning the image in the parallel direction, the read image can be rotated by 90 degrees to be printed, displayed or transmitted in a normal form. In this way, the present invention relates to a facsimile apparatus which is improved in usability.

[0003]

2. Description of the Related Art Conventionally, many facsimile machines have a structure of a reading section for reading only a sheet-like original document in view of the size of the apparatus. For this reason, it is impossible to directly read and transmit a book format book such as a bound notebook.

As a means for solving this difficulty, a reading section (consisting of a one-dimensional image sensor and not including a structure for feeding an original) is detachable from a facsimile apparatus of the main body, and the reading section is detached from the main body and manually operated. There is a device that scans the document surface with a scanner, or a device that has a reading unit (also called a so-called hand scanner, which also includes a one-dimensional image sensor) that manually scans the document surface separately from the reading unit of the main body. .

Further, it is completely separated from the main body, and the manuscript can be read anytime and anywhere. The reading result by the one-dimensional image sensor is temporarily stored in the hand scanner, and the read image information of the stored manuscript is stored. There is a hand scanner that can be transferred to a facsimile body for recording (printing output) or electric transmission.

In the case of this completely separate type hand scanner,
When storing the image information of the read document internally, since a large amount of image information of the document is stored for a limited storage capacity, encoding is performed to reduce the amount of information, and the encoded code is used. A method of storing the converted image information in an internal memory is adopted.

This encoding is usually performed in the main scanning direction of the hand scanner (direction of electrical scanning inside the one-dimensional image sensor).
MH (Modified
Huffman) or MR (Modified Read) coding is used. This is because it is the same as the encoding method at the time of facsimile transmission, and has the advantage that at the time of transmission to the partner machine, this encoded information can be transmitted without re-encoding. This is also because there is an advantage that the encoding means for transmission and the encoding means for temporary storage can be shared.

Not only the complete separation type hand scanner, but also the reading of a document and its transmission (to the partner facsimile machine)
In the case of a facsimile apparatus which is performed offline via the read image information storage means, the read image information is temporarily stored in terms of the storage capacity of the storage means (usually a semiconductor memory) in order to compress the read image information. Are stored and stored.

The encoding method at this time is the above-mentioned MH and MR.
Various types can be considered in addition to the encoding system. However, the order of encoding the read image information is the order of pixels obtained by scanning with the scanner (even in the case of a coding method such as DCT in which a two-dimensional set of pixels is a unit of coding, this two-dimensional The reading order in units of a set of pixels is normal. This is because the memory for encoding can be minimized by encoding and storing in order of the pixels captured by the scanner.

This is because, for example, if the read image is encoded in the order completely reverse to the order of the pixels read from the scanner (including the sub-scanning direction), the read result of one read document (scanner read) This is because a large-capacity memory for storing 1 bit per pixel, 1728 main scanning pixels, about 500 Kbytes of main scanning lines of 2,300 A4 originals) is required.

Here, when pixels of one scanning two-dimensional pixel set read by a hand scanner are arranged in the reading order,
{P00, P10,, PN0, P01, P11 ,,, PN1 ,,, P0M, P1M ,,
PNM} (where Pij represents one pixel, i represents the main scanning position, i = 0,
1, ..., N, j represents the sub-scanning position, and j = 0,
1, ..., M, and N and M are integers.
Encoding processing such as MH is performed using the main scanning pixel column {P0j, P1j, P2j, PNj} at a position j in the sub-scanning direction of the hand scanner as an encoding line.

This encoding process is performed in the order j = 0,1, j in the sub-scanning direction.
2, 2, and M, and the encoded results are sequentially stored in the encoded image information storage means (internal memory). Letting Cj (code information consisting of a plurality of bits) be the above encoding result for the main scanning pixel row at the position j in the sub-scanning direction of the hand scanner, Cj,
The encoding result for each main scanning pixel column of j = 0, 1, 2, ..., M is temporarily stored in the encoded image information storage means.

The read image information read by the hand scanner in this way is coded with the pixel row in the main scanning direction of the hand scanner as a coding line, and the coded image information coded in the sub-scanning direction is coded. It is temporarily stored in the image information storage means. The read image information is transmitted by transmitting the encoded image information in the encoded image information storage means into the main body facsimile apparatus and performing predetermined encoding (MH or the like).

In a facsimile machine, for example, a G3 facsimile machine, the scanning direction of reading on the transmitting side and recording on the receiving side (also referred to as printing) is set so that the image on the original read on the transmitting side can be reproduced as it is on the receiving side. It is prescribed as follows. The scanning direction is from left to right when viewing the read document vertically (this direction is called the main scanning direction), and the next scan is immediately below (called the sub-scanning direction) adjacent to the previous scan. .

Therefore, the image information read by the hand scanner is also scanned in the main scanning direction of the hand scanner from left to right with respect to the top and bottom of the document, and the sub scanning direction is also manually sub-scanned from top to bottom. On the assumption that the main scanning direction of the hand scanner corresponds to the main scanning direction of electric transmission, the sub-scanning direction of the hand scanner corresponds to the sub-scanning direction of electric transmission.

Assuming that the coding method of the coded image information is MH, the MH coded data Cj for each main scanning pixel row is j = 0, 1, 2, ...
As described above, the data is transmitted in the reading order (sub-scanning order). Further, in printing (so-called copy operation) or display in the main body device, the image image information of each main scanning pixel column decoded in the same correspondence relationship is supplied to the printing unit and the display unit.

As a result, the image read by the hand scanner is reproduced as a transmission result or a print / display result.
However, from the point of view of the structure of the hand scanner, when the main scanning direction of the hand scanner is from left to right with respect to the top and bottom of the read document, the sub scanning directions are from top to bottom and from bottom to top. Some are capable of sub-scanning in both directions.

In the case of such a hand scanner, when sub-scanning is performed by 180 degrees different from the original sub-scanning from the top to the bottom, the image information of each main scanning pixel row is transmitted or transmitted in the sub-scanning order. When it is supplied to the printing unit and the display unit, there is a problem that the reproduction image is reversed to the boundary image with respect to the read image in the transmission result or the printing and display result. As a publicly known example in which attention is paid to such a problem, there is, for example, JP-A-63-220657.

[0019]

Since the hand scanner itself manually scans the sub-scanning direction of the hand scanner, the sub-scanning direction relative to the main scanning direction of the hand scanner is essentially the same. 18 from the sub-scanning direction
Not only when it differs by 0 degrees,
Both horizontal and vertical directions can be freely moved and scanned as the sub-scanning direction.

Therefore, depending on which direction the hand scanner is moved and scanned with respect to the top-bottom direction of the document, the top-bottom direction of the reproduced image of the printing, display or transmission result may rotate.

FIG. 3 is an explanatory view showing the main scanning direction of the hand scanner and the manual sub-scanning direction. 1 in each figure
0 is the hand scanner, 10a is the main scanning direction of the hand scanner (when the hand scanner is composed of a one-dimensional reading sensor, the one-dimensional direction is the main scanning direction),
10b shows the sub-scanning direction. Further, (1) and (2) in each figure mean scanning (1) and scanning (2), which means the movement / scanning of the hand scanner when reading one sheet of the original document by scanning twice. It is shown.

FIG. 3A shows a case where a handwritten document is moved (sub-scanning) horizontally from left to right with respect to the top and bottom of the original, and FIG. 3B shows the horizontally written document vertically from top to bottom. In the case of moving in the direction (sub-scanning), (c) shows the case of moving the vertical writing document in the horizontal direction (sub-scanning), and (d) in the case of moving the vertical writing document in the vertical direction (sub-scanning).

As described above, the main scanning direction of the hand scanner corresponds to the main scanning direction of electric transmission and the sub-scanning direction of the hand scanner corresponds to the sub-scanning direction of electric transmission, as described above. When the coded image information of the main scanning pixel row or the decoded image image information in the sub-scanning order is transmitted, printed, or supplied to the display unit, the reproduced images are reproduced with respect to the top and bottom of the read document, as shown in FIG. 90
It becomes a rotated image.

As in the scans of (b) and (d) in FIG.
When the main scanning direction of the hand scanner is from left to right and the sub scanning direction is from top to bottom with respect to the top and bottom of the scanned document, and the main scanning direction and sub scanning direction of facsimile transmission match, the top and bottom of the reproduced image of the transmission result. The direction corresponds to the vertical direction of the read document, as shown in (b) and (d) of FIG.

However, as shown in (a) and (c) of FIG. 3, the main scanning of the hand scanner is from bottom to top and the sub-scan is from left to right with respect to the top and bottom of the read document by facsimile. When the main scanning direction and the sub-scanning direction of electric transmission are different from each other and the scanning direction of the hand scanner is different from the scanning direction of electric transmission by 90 degrees, the vertical direction of the reproduced image of the electric transmission result is (a) and (a) of FIG. As in c), the image becomes an image rotated 90 degrees to the right with respect to the vertical direction of the read document.

In particular, scanning (1) and scanning (2) shown in FIG.
As shown in FIG. 3, when one original is read by a plurality of scans of the hand scanner and is transmitted by electric power, if each scanning direction is different from the scanning direction of electric transmission by 90 degrees as shown in (a) and (c) of FIG. As a result, as shown in FIGS. 4A and 4C, the read images by scanning (1) and scanning (2) are rotated by 90 degrees.

Further, if the image read by the scanning (1) and scanning (2) of the hand scanner is simply transmitted as one original document (total two sheets are transmitted), scanning (1) results as shown in FIG. The image of scanning (2) is rotated by 90 degrees, and the read original is separated into scanning (1) and (2), so that the relative positional relationship between the boundary regions of scanning (1) and (2) is easily achieved. There is a difficulty that it cannot be read.

In the cases of FIGS. 3 (b) and 3 (c), 90 ° rotation does not occur, but the read document is separated into scanning (1) and scanning (2), and the same problems as described above occur.

The object of the present invention is to solve the above problems,
Even if the sub-scanning direction of the hand scanner moves and scans from the left to the right with respect to the top and bottom of the read document, the top and bottom of the reproduced image of the transfer result or print or display result is transferred by 90 degrees or not. Another object of the present invention is to provide a facsimile device capable of printing and displaying.

Further, in the case of reading one original by a plurality of scans, the read originals are separated by each scan, but the reproduced image image of each scan maintains the relative positional relationship of each scan of the original, An object of the present invention is to provide a facsimile apparatus capable of transmitting and reproducing an image that can substantially retain the image of a read document.

[0031]

A first solution is a sub-scanning direction instruction switch (SW) for instructing a hand scanner unit in a scanning direction (that is, a sub-scanning direction) for manually scanning the hand scanner in a facsimile apparatus. ) Means and sub-scanning direction instruction information storage means for storing the sub-scanning direction instruction information instructed by the sub-scanning direction instruction switch (SW) means at the time of scanning in association with the encoded image information which is read information compressed by the scanning. Is provided

An image information storage means for storing the two-dimensional image information decoded by the hand scanner image decoding means in the main body facsimile apparatus, and two of the image information storage means.
A 90-degree coordinate conversion means for converting the vertical direction of the three-dimensional image by 90 degrees is provided,

When the sub-scanning direction instruction information of the sub-scanning direction instruction information storage means fetched from the hand scanner section indicates the horizontal scanning with respect to the top and bottom of the document, the corresponding encoded image information is decoded by the hand scanner image decoding. The image information storage means is decrypted and stored in the image information storage means, the two-dimensional image in the image information storage means is subjected to coordinate conversion by the 90-degree coordinate conversion means, and the image information after the 90-degree coordinate conversion is printed or predetermined. It was decided to send in the format of.

A second solution is to cut out a specific character from the image data read by the hand scanner in a facsimile machine, and determine the vertical direction of the character in the main scanning direction of the hand scanner (rotation by 90 degrees) or in the hand. A character rotation detecting means for detecting whether the scanner is in the sub-scanning direction (upright) is provided,

When the detection result of the character rotation detecting means is in the main scanning direction of the hand scanner, it is judged that the document is scanned in the lateral direction with respect to the top and bottom, and the encoded image information is processed by the hand scanner image decoding means. The decoded information is stored in the image information storage means, the two-dimensional image in the image information storage means is subjected to coordinate conversion by the 90-degree coordinate conversion means, and the image information after the 90-degree coordinate conversion is printed or in a predetermined format. It was decided to send in.

A third solution is to detect a change pattern in the sub-scanning direction of the number of black pixels of each main-scanning pixel row of the hand scanner from the image data read by the hand scanner in the facsimile apparatus, and detect the change pattern. In the row direction detection means for detecting whether the increase or decrease in the number of black pixels is a certain value or more and has a substantially constant cycle,

When the detection result of the row direction detecting means is negative, the coded image information is decoded by the hand scanner image decoding means and stored in the image information storing means, and the two-dimensional image of the image information storing means is obtained. The image is subjected to coordinate conversion by the 90-degree coordinate conversion means, and the image information after the 90-degree coordinate conversion is printed or transmitted in a predetermined format.

A fourth solving means is, in a facsimile apparatus, a sub-scanning direction designating switch means for designating the sub-scanning direction of the hand scanner or a sub-scanning direction with respect to the top and bottom of the original of the hand scanner from the two-dimensional image image read by the hand scanner. Sub-scanning direction detecting means for detecting information for detecting the two-dimensional image information, two-dimensional image information storing means for storing the two-dimensional image image of the hand scanner, and the vertical direction of the two-dimensional image of the two-dimensional image information storing means is 90 degrees. The 90-degree coordinate conversion means for coordinate conversion, the operation result of the sub-scanning direction instruction switch of each two-dimensional image obtained by the plurality of scans of the hand scanner, or the detection result of the sub-scanning direction detection means are continuous in the scanning order. Provided is sub-scanning direction coincidence detecting means for detecting whether or not the two two-dimensional image images coincide with each other. Together,

When the detection result of the sub-scanning direction coincidence detecting means is positive and the operation result of the sub-scanning direction indicating switch means or the detection result of the scanning direction detecting means is vertical scanning, the two continuous two-dimensional image images are Main scanning pixel row {Pij, i = 0,1,2,, N} at the sub-scanning position j of the preceding two-dimensional image image in the scanning order and sub-scanning position j of the following two-dimensional image image in the scanning order Main scanning pixel column {Qij, i =

In such a case, each two-dimensional image image is subjected to coordinate conversion by the 90-degree coordinate conversion means, and the two-dimensional image image after the 90-degree coordinate conversion is supplied to the printing unit or the encoding unit for electric transmission. That is what I did.

N, j represents the sub-scanning position, and j = 0, 1, ..., M
And N and M are integers, respectively.

[0042]

According to the first solution, when the document is scanned by the hand scanner, whether the vertical scanning (from the top to the bottom) or the horizontal scanning (from the left to the right) of the top and bottom of the document is sub-scanned. The scanning direction instructing SW means gives an instruction to start scanning.

By this instruction operation in the scanning direction, the instruction information is stored in the sub-scanning direction instruction information storage means in correspondence with the read image information read and encoded by the scanning and stored in the encoded image information storage means. It is possible to determine in which direction the scanned image information of each scan of the encoded image information storage means is scanned by the instruction information of the corresponding sub-scanning direction instruction information storage means.

Therefore, by performing the 90-degree coordinate conversion on the read image information in which the instruction information indicates the horizontal direction, it is possible to prevent the reproduced image from rotating by 90 degrees.

In the second solving means, the character rotation detecting means detects whether or not the top and bottom of the characters in the image data read by scanning coincide with the main scanning direction of the hand scanner. If they match in the scanning direction, assuming that the top and bottom of the original match the top and bottom of the characters in the original, the subscan of the hand scanner scans horizontally (left to right) with respect to the top and bottom of the original. It is possible to determine that the read image information has been rotated, and in this case, by performing 90-degree coordinate conversion on the read image information, it is possible to prevent rotation of the reproduced image by 90 degrees.

According to the third solution, when a horizontally-written document is vertically scanned by the hand scanner, the change pattern of the number of black pixels in the main scanning direction of the hand scanner with respect to the sub-scanning direction of the hand scanner includes the number of black pixels in the line. It uses the property that it increases with, decreases between lines, and the cycle of increase and decrease depends on the arrangement pitch of lines.
The above property disappears, and the detection result of the row direction detection means becomes negative.

In this case, by performing 90-degree coordinate conversion on the read image information, it is possible to prevent rotation of the reproduced image by 90 degrees. However, although this solution is effective for a horizontally written document, it has an adverse effect for a vertically written document. However, it is effective for users who mainly write horizontal documents, or for specific users such as those in the Western world.

In the fourth solving means, when one original is read by a plurality of scans, the sub-scanning direction of the original of the hand scanner can be detected by the operation result of the sub-scanning direction instruction switch means or the scanning direction detecting means. Therefore, when the detection result is horizontal scanning, the read image is prevented from rotating by 90 degrees by converting the read image by 90 degree coordinate by the 90 degree coordinate converting means and transmitting the converted image in the printing unit or in a predetermined format. In addition, since the reproduced images can be arranged in the order of scanning from top to bottom, the image image of the document can be reproduced.

When the vertical scanning is performed and the detection result of the sub-scanning direction coincidence detecting means is affirmative, at least two images read by the vertical scanning by the image synthesizing means are associated with the sub-scanning positions by the main scanning of each hand scanner. Since the composite image in which the scanning pixel rows are arranged on the left and right in the main scanning direction is combined, the reproduced image is arranged in the scanning order from the left by transmitting the combined new main scanning pixel row in the printing unit or in a predetermined format. As a result, the image of one read document can be reproduced.

As a result, as shown in FIGS. 4 (b) and 4 (c), the reproduced images by each scanning are arranged in the scanning order downward, and the relative positional relationship of the scanning boundary area cannot be easily read. In addition to solving the problem, in the case of reproducing an image on the thermal paper, it is possible to avoid wasteful use of the thermal paper and improve the utilization efficiency.

However, in this case, it is premised that each scanning area of a plurality of scans moves from the upper part to the lower part of the document in the case of horizontal scanning and from the left part to the right part of the document in the case of vertical scanning. .

Next, the hand scanner 1 which is the main object of the present invention
When the original is read at 0 and sent to the other facsimile machine, and when the original is recorded in the recording unit 7 of the own machine, copy is reproduced.
The operation will be described.

First, the reading operation of the document by the hand scanner 10 is performed as follows. Position the hand scanner 10 at the upper left part of the area to read the top and bottom of the read document, operate the sub-scanning direction instruction switch 105 to instruct the sub-scanning direction, and start / end scanning.
While pressing the stop switch 108a, the hand scanner 10 scans the document surface in the sub-scanning direction previously instructed, and at the end of scanning, the start / stop switch 108
Open a.

In the sub-scanning direction, as shown in FIG. 3, when the hand scanner 10 is scanned and moved from left to right with respect to the top and bottom of the document as shown in FIGS. Is referred to as horizontal scanning, and the case of scanning / moving from top to bottom as in (b) and (d) is referred to as vertical scanning, and the corresponding sub-scanning direction indicating switch 105 is operated, or the sub-scanning direction indicator lamp is operated. 105a displays the corresponding sub-scanning direction,
The sub-scanning direction instruction switch 105 is operated.

As the operation result of the sub-scanning direction instruction switch 105, the operation result at the time when the start / stop switch 108a is pressed is stored in a predetermined area of the sub-scanning instruction information memory.

A light source (not shown) for reading a document while the start / stop switch 108a is being pressed
Is illuminated and the original is illuminated. One-dimensional reading sensor 101
In accordance with the reflected light from the document, the output voltage of the photoelectric conversion element arranged inside each sensor is output in series on a pixel-by-pixel basis. If the number of photoelectric conversion elements of the one-dimensional reading sensor 101 is N + 1, the series of output voltages of N + 1 pixels corresponds to the reading result of the main scanning pixel column. (This may also be referred to as a main scanning line reading result hereinafter.)

The output of the main scanning line detects the moving distance in the sub-scanning direction based on the sub-scanning roller provided in the hand scanner 10 and the encoder (not shown) for detecting the rotation of the roller. Every time a predetermined amount of movement is performed, the hand scanner control unit 108 controls the sensor control unit 102 so that the one-dimensional reading sensor 101 outputs the reading result of the main scanning line of the document for each predetermined amount of sub-scanning. .

The reading result of the main scanning line from the one-dimensional reading sensor 101 is supplied to the scanner image coding unit 103 for each predetermined amount of sub-scanning, coding is performed for information compression, and the coding result is obtained. Are stored in a predetermined area of the scanner encoded image information memory 104 in the sub-scanning order.

The scanner image coding unit 103 first quantizes the reading result of the main scanning line for coding. Here, in order to avoid the complexity of the description, it is assumed that quantization is performed into a binary value of white or black.

The main-scanning pixel row at the sub-scanning direction position j quantized into two values is {Pij: i = 0, N} = {P0j, P1j, P2j ,,, PNj} i: Hand scanner main scanning direction position j: Hand scanner sub-scanning direction position

In this case (provided that Pij represents one pixel), the scanner image coding unit 103 uses this N + 1.
Encoding for information compression is performed in units of the quantized value sequence of each pixel. Encoding is MH encoding, MR encoding, or the like.

The encoding result of the quantized main scanning pixel column {Pij: i = 0, N} at the position j in the sub-scanning direction is Cj (code information consisting of a plurality of bits, where j represents the position in the sub-scanning direction). Then, the encoding result for each main scanning pixel column of Cj, j = 0, 1, 2, M is the scanner encoded image information memory 10 in the sub-scanning order.
4 is stored in a predetermined area. Number of main scan pixel rows (M
+1) is proportional to the moving distance of the sub-scan. The encoding result Cj includes the encoding information of the quantized main scanning pixel row and the line end code (EOL) indicating the end of the main scanning line.

As described above, the coded image information of the coded read image is stored in the scanner image coding memory 104 by one scan, and the hand scanner for the corresponding read original is stored in the sub-scanning direction instruction information memory 106. The 10 sub-scanning directions are respectively stored as vertical or horizontal information.

The scanner-encoded image information memory 104 stores the encoded image information of each read original by scanning a plurality of times within an allowable range of the memory capacity. At the same time, in the sub-scanning direction instruction information memory 106, the sub-scanning direction of the hand scanner 10 with respect to the read document, which is the operation result of the sub-scanning direction instruction switch 105, corresponds to the encoded image information by each scan. Is stored as information. The contents of both memories are backed up and held by the battery 109.

In this way, the image information read by the hand scanner 10 is transferred to the data transfer I / F unit 107 and the hand scanner I / F of the main body by mounting the hand scanner 10 on the facsimile apparatus of the main body. Part 11
It is taken into the main body side via. The content of the scanner encoded image information memory 104 is the encoded image information memory 3
Then, the contents of the sub-scanning direction instruction information memory 106 are transferred to the sub-scanning direction instruction information memory 14 on the main body side.

Next, the transfer of the image information taken from the hand scanner 10 and the copy operation will be described. Transmission of the encoded image information from the hand scanner 10 stored in the encoded image information memory 3 is performed as follows.

First, the sub-scanning direction instruction information stored in the sub-scanning direction instruction information memory 14 corresponds to the encoded image information to be transmitted, and the sub-scanning direction instruction information of the hand scanner 10 determines whether the vertical scanning or the horizontal scanning is performed by the system control. Part 8 does. When the identification result is the vertical direction, (b) and (d) of FIG. 3 and (b) of FIG.
As shown in (d), even if the main scanning direction of electric transmission corresponds to the main scanning direction of the hand scanner 10 and the sub-scanning direction of electric transmission corresponds to the sub-scanning direction of the hand scanner 10, the top and bottom of the reproduced image of the electric transmission result. Corresponds to the top and bottom of the read document, the coded image information in the coded image information memory 3 is sequentially read,
It is converted into coded information for electric transmission and is transmitted to the facsimile machine of the other party from the line 6 via the modem 4 and the NCU unit 5.

At this time, if the encoding method of the scanner image encoding unit 103 of the hand scanner 10 is different from the encoding method for electric transmission during electric transmission, the encoded information Cj is sub-scanned from the encoded image information memory 3. In order (j = 0,1,2,, M), the hand scanner image decoding unit 12 decodes the image image (a series of white and black), and the main scanning pixel column of the decoded hand scanner { Pij: i = 0,1,2,, N} is supplied to the transmission encoding / decoding unit 2 in units of main scanning pixel columns, encoding processing for transmission is performed, and the encoding result is transmitted.

Such a case occurs when the encoding system of the scanner image encoding unit 103 is the MR system and the transmission encoding system has only the MH system in terms of the function of the partner facsimile machine. In addition, the scanner image encoding unit 10
When the coding method of No. 3 is a coding method having a higher information compression rate than the MH and MR methods used in transmission, the above conversion of the coding method (conversion to MH method or MR method) is always performed during transmission. Will need to be converted).

If the identification result of the sub-scanning direction indication information is horizontal scanning, (a), (c) of FIG. 3 and (a) of FIG.
As shown in (c), the main scanning direction and sub-scanning direction of the electric transmission are made to correspond to the main scanning direction and the sub-scanning direction of the hand scanner 10 as in the case of the vertical scanning, and the encoded image information is obtained by the above operation. When the encoded image information in the memory 3 is transmitted, as described above, the top and bottom of the reproduced image are 9 times the top and bottom of the read document.
In this case, the image of the read document is rotated by 90 degrees by using the 90-degree coordinate conversion unit 15, and the code is transmitted for transmission.

Here, FIG. 5 shows how the top and bottom of the reproduced image are rotated in the transmission result of the read image by vertical scanning and horizontal scanning.
This will be described in more detail with reference to FIG.

FIG. 5 shows a hand scanner 1 for vertical scanning.
A pixel {Pij} quantized by reading with 0 (i is the position in the main scanning direction of the hand scanner 10, j is the hand scanner 10
FIG. 5 is an explanatory diagram showing a relative positional relationship of (sub-scanning position of) and a positional relationship of the document with respect to the top and bottom.

In the case of this vertical scanning, the main scanning direction and the sub scanning direction of the electric transmission, which are regulated in terms of electric transmission with respect to the top and bottom of the document, coincide with both the main scanning direction and the sub scanning direction of the hand scanner 10. Since the main scanning direction and the sub-scanning direction of the hand scanner 10 correspond to the main scanning direction and the sub-scanning direction of the electric transmission, the top and bottom of the reproduced image of the transmission result coincide with the top and bottom of the read image.

FIG. 6A is an explanatory view showing the case of horizontal scanning. In this case, the contents of the pixel {Pij} are different from those in FIG. 5, that is, the top and bottom of the read document are as shown in FIG.
The right side is the top of the read document and the left side is the place of the read document.
Unlike the vertical scanning of, the vertical relationship is rotated by 90 degrees.

In this state, when the main scanning direction and the sub-scanning direction of the hand scanner 10 are made to correspond to the main scanning direction and the sub-scanning direction of the electric transmission in the same manner as the vertical scanning, the reproduction image of the electric transmission result is the top and bottom of the read original. It will rotate 90 degrees to the top and bottom. (Note that the diagonally hatched rows in FIGS. 5 and 6 show each main scanning pixel column of the hand scanner 10.)

Therefore, in the case of horizontal scanning, the image of the read original is rotated by 90 degrees as follows. First, the system control unit 8 sets the encoded image information Cj (j indicates the sub-scanning position of the hand scanner 10) to be transmitted stored in the encoded image information memory 3 in the sub-scanning order (j of the hand scanner 10). = 0,1,2 ,,, M), sequentially decoded by the hand scanner image decoding unit 12, and quantized main scanning pixel row {Pij, i = 0,1,2,, N corresponding to Cj. } Is reproduced. Then, the decoded quantized main scanning pixel row is sequentially stored in the two-dimensional image information memory 13.

The two-dimensional image information memory 13 is stored in the two-dimensional image information memory 13 so that the relative positional relationship between the decoded main scanning pixel columns is arranged as shown in FIG. The quantized pixel {Pij} can be accessed corresponding to the position i in the main scanning direction and the position j in the sub scanning direction.
Each quantized pixel {Pij} is stored in a predetermined address area (address value). The storage position (address value) in the two-dimensional image information memory 13 of each quantized pixel {Pij} is controlled by the system control unit 8.

In this way, the two-dimensional image of the image read by the hand scanner 10 is developed and reproduced on the two-dimensional image information memory 13. The 90-degree coordinate conversion unit 15
The reading order of the two-dimensional image image on the two-dimensional image information memory 13 is different from the storage order by the system control unit 8 described above, and the quantized pixels {Pij} are read to read the two-dimensional image image at the 90-degree coordinate. Do the conversion.

The system control unit 8 stores each decoded quantized pixel {Pij} in the two-dimensional image information memory 13 [{Pij: i = 0,1,2,, N} j = 0,1, 2,3,, M] i: Hand scanner main scanning direction position j: Hand scanner sub scanning direction position are stored in the address value corresponding to ij in this order.

On the other hand, the 90-degree coordinate conversion unit 15 [[Pij: j = 0,1,2 ,,, M} i = N, N-1,, 2,1,0] i: hand Scanner main scanning direction position j: Hand scanner sub-scanning direction position, that is, in the order of j = 0,1,2,3, M for a certain value of i, a pixel consisting of M + 1 pixels The column is set as a new main scanning pixel column, and this new main scanning pixel column is i = N, N-1,
Read in the order of N-2, 2, 2, 1, 0.

Specifically, the reading order of the quantized pixels {Pij} is {PN0, PN1, PN2, PN3 ,, PNj ,, PNM} ... {P20, P21, P22, P23 ,,, P2j ,, P2M} {P10, P11, P12, P13 ,,, P1j ,, P1M} {P00, P01, P02, P03,, P0j ,, P0M} In the pixel row, the order of each new main scanning pixel row is j = N ,, 2,1,0.

As described above, the 90-degree coordinate conversion unit 15
The new main-scanning pixel row read out from the two-dimensional image information memory 13 is sequentially supplied to the electric-transmission encoding / decoding unit 2 in units of main-scanning pixel rows, and encoding for electric transmission is performed. The encoded coded information for transmission is the modem 4, the NCU unit 5
The data is transmitted from the line 6 to the facsimile machine of the partner machine via.

In the copy operation in the case of horizontal scanning, the new main scanning pixel row read from the two-dimensional image information memory 13 by the 90-degree coordinate conversion section 15 as described above is recorded in the recording section 7 in units of main scanning pixel rows. Reproduced images are obtained by sequentially supplying.

By the coordinate conversion of the 90-degree coordinate conversion unit 15, the scanning order of each quantized pixel is the same in both the electric transmission and the copy operation. As shown in FIG. With respect to the top and bottom, the new main scanning direction can coincide with the left-to-right direction specified in the electric transmission, and the new sub-scanning direction can coincide with the top-down direction specified in the electric transmission.
The top and bottom of the reproduced image and the top and bottom of the read image can be made equal.

As described above, in the first embodiment,
The sub-scanning direction with respect to the top and bottom of the document read by the hand scanner 10 is stored in the sub-scanning direction instruction information memory 14 in accordance with the instruction result obtained by operating the sub-scanning direction instruction switch 105 in correspondence with the encoded image information read by the scanning. Since the stored value is stored, the sub-scanning direction of the hand scanner 10 can be discriminated. When the discrimination result is the lateral direction, the read image information is subjected to 90-degree coordinate conversion to prevent rotation of the reproduced image by 90 degrees. be able to.

(Second Embodiment) Next, a second embodiment of the present invention is shown in FIG. In this embodiment, the hand scanner is not of the completely separated type, but the hand scanner is connected to the data bus 9 of the facsimile apparatus main body. The blocks having the same functions as in FIG. 1 are given the same numbers.

The hand scanner 10 includes a one-dimensional reading sensor 101, a sensor control unit 102 for controlling this operation, a sub-scanning direction indicating switch 105, and a sub-scanning direction indicator lamp 105.
a and a start / stop switch 108a. The operation of the hand scanner 10 is controlled by the system controller via the data bus 9.

The difference from the first embodiment described above is that the main-scanning pixel row read by the scanning of the hand scanner 10 is directly encoded by the hand-scanner image encoding unit 103 of the main body apparatus via the data bus 9. The point where the encoding result is stored in the encoded image information memory 3. Further, the operation result of the sub-scanning direction instruction switch 105 is also stored directly in the sub-scanning direction instruction information memory 14 of the main body apparatus via the data bus 9.

Others are the same as in the first embodiment, and when the stored value of the sub-scanning direction instruction information memory 14 is horizontal scanning, the encoded image information of the corresponding encoded image information memory 3 is read out and the hand scanner image code is read. The decryption unit 12 decrypts the data to 2
A two-dimensional image image is reproduced on the three-dimensional image information memory 13. The 90-degree coordinate conversion unit 15 converts this image image into 2
A new main-scanning pixel row, which has been read in from the three-dimensional image information memory 13 in a different reading order and has undergone 90-degree coordinate conversion, is supplied to the transmission encoding / decoding unit 2 in main-scanning pixel row units.

The image information coded for transmission is transmitted to the partner facsimile machine from the line 6 via the modem 4 and the NCU unit 5. Further, in the copy operation, the new main-scanning pixel column whose 90-degree coordinate has been converted is supplied to the recording unit 7 in units of main-scanning pixel column, and the read image is reproduced.

In the second embodiment, as in the first embodiment, as for the sub-scanning direction with respect to the top and bottom of the document read by the hand scanner 10, the instruction result by the operation of the sub-scanning direction instruction switch 105 is read by the scanning. Since it is stored in the sub-scanning direction instruction information memory 14 corresponding to the encoded image information, the sub-scanning direction of the hand scanner 10 can be discriminated from this stored value. If the discrimination result is the lateral direction, the read image information is 90 By converting the degree coordinates, 90
The rotation of the degree can be prevented.

(Third Embodiment) Next, a third embodiment of the present invention is shown in FIGS. In this embodiment, the sub-scanning direction indicating switch 10 of the first and second embodiments is used as the sub-scanning direction with respect to the top and bottom of the document read by the hand scanner 10.
Instead of the operation of 5, the character rotation detection unit that detects whether the top and bottom of the characters in the image data read by scanning match (horizontal scanning) in the main scanning direction of the hand scanner 10 (vertical scanning). 16, a horizontal scanning or a vertical scanning is discriminated based on the detection result, and in the case of the horizontal scanning, 90-degree coordinate conversion is performed to prevent the reproduced image from rotating by 90 degrees. The blocks having the same functions as in FIG. 1 are given the same numbers.

FIG. 8 shows the overall construction of the third embodiment, FIG. 9 shows the construction of the hand scanner 10, and FIG. 10 shows the construction of the newly provided character rotation detector 16.

Reference numeral 16 in FIG. 7 denotes a character rotation detecting section provided in place of the sub-scanning direction instruction information memory 14 in the first and second embodiments, which is included in the image data read by the scanning of the hand scanner 10. It is detected whether or not the top and bottom of the character coincide with the main scanning direction of the hand scanner 10 (horizontal scanning) or not (vertical scanning).

As shown in FIG. 9, the construction of the hand scanner 10 in this embodiment is different from that of the hand scanner 10 of the first embodiment in that it has a sub-scanning direction indicating switch 105, a sub-scanning direction indicator lamp 105a and a sub-scanning direction information memory. This is a configuration excluding 106.

Further, the character rotation detecting section 16 is a character cutting section 161 for cutting out a character from the two-dimensional image image read and decoded by the hand scanner 10 supplied from the two-dimensional image information memory 13 and a standard character. Standard character pattern memory 16 that stores (plural) patterns
3. In addition to having a character pattern rotating unit 164 that outputs the character pattern output from the standard character pattern memory 163 in character units as it is, or

A pattern matching unit 162 for calculating the degree of similarity between the character pattern in the read document output from the character cutting unit 161 and the standard character pattern output from the character pattern rotating unit 164, the degree of similarity with each standard character pattern. It has a maximum similarity value indicating the maximum similarity among the calculation results and a maximum similarity detection unit 165 for detecting the rotation direction value of the character pattern rotation unit at that time.

Based on the maximum similarity value and the rotation direction value output from the maximum similarity detection means 165, the rotation direction of the character in the read document (with respect to the main scanning direction of the hand scanner 10).
And a character rotation detection control unit 167 for controlling the operations of these units.

Next, the operation of the third embodiment will be described. In the description of this operation, points different from the operations of the first and second embodiments will be described.

The reading operation of the original by the hand scanner 10 is performed as follows. That is, the hand scanner 10
Is positioned at the upper left part of the area to be read with respect to the top and bottom of the read document, and the start / stop switch 108a is pressed to move / scan (sub-scan) the document surface, and the start / stop switch 108a is opened at the end of the scan. .

This start / stop switch 108a
The pressed section document of is read by the one-dimensional reading sensor 101, the scanner image encoding unit 103 performs encoding for information amount compression, and the scanner encoded image information memory 1
It is temporarily stored in 04. The image information stored in the scanner-encoded image information memory 104 is stored in the hand scanner 1
For example, by mounting 0 in the facsimile device of the main body, it is taken into the encoded image information memory 3 of the main body through the data transfer I / F unit 107 and the hand scanner I / F unit 11 of the main body.

Next, the transfer of image information captured by the hand scanner 10 and the copy operation will be described.
First, in order to determine whether the image information captured by the hand scanner 10 is obtained by vertical scanning or horizontal scanning of the top and bottom of the document of the hand scanner 10, a character rotation detection unit It is detected by 16 whether or not the top and bottom of the characters in the read image coincide with the main scanning direction of the hand scanner 10 (horizontal scanning).

For this detection, the system control unit 8 converts the coded image information read by the hand scanner 10 of the coded image information memory 3 into the hand scanner image decoding unit 1.
Decoding is performed in step 2, and the decoded two-dimensional image image is reproduced on the two-dimensional image information memory 13. The character rotation detection unit 16 cuts out a character in the read document as a character pattern for each character based on the two-dimensional image image on the two-dimensional image information memory 13 by the character cutting unit 161. This character cutout can be performed by various cutout methods used in a known OCR (optical character reading device) such as that described in Japanese Patent Publication No. 4-20507.

For example, by utilizing the fact that character strings (mostly black pixels) are separated by white spaces between lines, when a two-dimensional image image is cut out in a fixed rectangular area as shown in FIG. If the number of black-and-white change points or the number of black pixels in a region at a certain Y value is taken, there are many in a row as shown in FIG.
It has a small distribution between rows. Further, the distribution at a certain X value in the direction perpendicular to the character line is substantially uniform and continuous as shown in FIG. 11 (c). By this, the line direction can be detected and the character line can be cut out.

Since each character is separated from the cut-out character line by a white character space, the distribution pattern of the number of change points or the number of black pixels is small between characters as shown in FIG. 11 (e). It becomes large in the character part, so that each character can be cut out in character units.

The character cutout unit 161 cuts out the two-dimensional image image in the circumscribed rectangular area of one character as a cutout character pattern from the two-dimensional image information memory 13 as described above, and temporarily stores it in the character cutout unit 161. Remember.

The standard character pattern memory 163 stores Japanese kanji, katakana, hiragana, alphanumerics, symbols, and character patterns of each country, and the pattern rotating unit 164 performs a pattern for each character pattern of one character. It is supplied to the matching unit 162. The pattern rotating unit 164 directly receives the pattern matching unit 162 for one character pattern supplied from the standard character pattern memory unit 163.
Then, the same standard character pattern is rotated 90 degrees to the right and supplied to the pattern matching unit. This 90 ° right rotation rotates the standard character pattern in the same manner as the 90 ° coordinate conversion unit 15 described above.

The pattern matching unit 162 outputs one cut-out character pattern supplied from the character cut-out unit 161, all standard character patterns supplied from the standard character pattern memory 163 via the pattern rotation unit 164, and its right rotation. Calculate the similarity with the character pattern
The calculated similarity value and the rotation direction at that time (whether it is as it is or rotated by 90 degrees to the right) are the maximum similarity detection unit 16 for each pattern.
Supply to 5.

The maximum similarity detecting section 165 detects the maximum value of the respective similarity values inputted and the rotation direction corresponding to the maximum value, and supplies this to the character direction detecting section 166.
This series of processes is performed on a plurality of cut-out character patterns cut out at a plurality of different places in the read image.

Based on the maximum similarity value and the rotation direction value for a plurality (N) of cut-out character patterns, the character direction detection unit 166 determines that the maximum similarity is greater than the threshold value for a certain amount of N or more. If there is a degree value and the corresponding rotation direction values are the same, it is judged that the vertical direction of the character in the read document has been detected, and the rotation direction value (whether it is the same as the vertical direction of the standard character pattern or 90 degrees to the right) is detected. ) Is output. If the above conditions are not satisfied, a result indicating that detection is impossible is output.

FIGS. 12A and 12B are explanatory views showing the operation of the character rotation detecting section 16, where FIG. 12A shows the case of vertical scanning and FIG. 12B shows the case of horizontal scanning. In the case of vertical scanning, the top and bottom of the characters of the cut-out character pattern are rotated 90 degrees counterclockwise with respect to the main scanning direction of the hand scanner as shown in (1).

The pattern matching unit 162 includes a standard character pattern memory 163 via a pattern rotating unit 164.
As shown in (2) to (5) in FIG. 12, upright and right 9
Since the character pattern rotated by 0 degrees is supplied, the maximum similarity is given by (2) in this case.

In the case of horizontal scanning, the top and bottom of the characters of the cut-out character pattern are (1) as shown in FIG.
As described above, the maximum similarity is given by (3) rotated 90 degrees to the right, which coincides with the main scanning direction of the hand scanner.

Therefore, when the rotation direction value of the detection result of the character rotation detection unit 16 is 90 degrees to the right, the hand scanner can determine that the document is horizontally scanned with respect to the top and bottom. Further, when the top and bottom of the standard character pattern are the same, it can be determined that vertical scanning has been performed. If the detection result cannot be determined, the result is regarded as vertical scanning. (Therefore, the image read by the hand scanner 10 is not rotated by 90 degrees, but is transmitted or printed)

As described above, in the third embodiment, the character rotation detection unit 16 can determine the sub-scanning direction of the original of the hand scanner 10 with respect to the top and bottom, and thus the above-mentioned first and second
Similar to the second embodiment, when the sub-scanning direction is the horizontal scanning, the read image is converted by 90 degree coordinate conversion so that the reproduced image can be displayed in 9
It is possible to prevent 0 degree rotation.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be shown in FIGS. In this embodiment, instead of the character rotation detection unit 16 of the third embodiment, a line direction detection unit 17 for detecting the direction of a character line from the image data read by scanning is provided, and the horizontal scanning is performed depending on the detection result. If it is vertical scanning, 90 degree coordinate conversion is performed for horizontal scanning,
This is to prevent 90 ° rotation of the reproduced image.

The blocks having the same functions as in FIG. 8 are assigned the same numbers. FIG. 13 shows the overall configuration of the fourth embodiment, and FIG.
The respective configurations are shown. The configuration of the hand scanner unit 10 is the same as that of the third embodiment as shown in FIG.

As shown in FIG. 14, the line direction detecting section 17 detects the hand scanner 1 from the two-dimensional image information memory 13.
The image cut-out memory 171, which temporarily stores the two-dimensional image image in the partial rectangular area of the two-dimensional image image read and decoded by 0, the address control unit 172 which controls the address of the image cut-out memory 171, and the image cut-out memory In addition to including a black pixel counting unit 173 that counts the number of black pixels in the main scanning pixel column or the sub-scanning pixel column of the hand scanner 10 output from 171.

Main scanning black pixel number change pattern memory 17 for storing the black pixel total value of the main scanning pixel column in the sub scanning direction.
4. Sub-scanning black pixel number change pattern memory 175, 1 for storing the black pixel count value of the sub-scanning pixel row in the main scanning direction
Change amount detection units 176 and 174 for detecting the change amounts of the black pixel number change patterns stored in 74 and 175, respectively.
And a periodicity detection unit 177 for detecting the presence or absence of the periodicity of the black pixel number change pattern stored in 175 and 175, respectively.

Change amount detector 176 and periodicity detector 177
Direction determining section 17 for determining the row direction based on the detection result of
8 and a row direction detection control unit 179 for controlling the operation of each block.

Next, the operation of the fourth embodiment will be described.
In the description, the points different from the operation of the above-described embodiment will be described.

The row direction detecting section 17 determines whether the image information taken in from the hand scanner 10 is obtained by vertical scanning or horizontal scanning of the top and bottom of the original of the hand scanner 10. Therefore, as in the case of the third embodiment, the system control unit 8 decodes the coded image information read by the hand scanner 10 of the coded image information memory 3 by the hand scanner image decoding unit 12, The decoded two-dimensional image image is reproduced on the two-dimensional image information memory 13.

The row direction detection unit 17 detects the row direction based on the two-dimensional image image developed on the two-dimensional image information memory 13 as follows.

First, from the two-dimensional image information memory 13, 2
A partial rectangular area of the three-dimensional image is cut out and temporarily stored in the image cutout memory 171. The size of the rectangular area is n, which is the number of pixels n in the main scanning direction and the number of pixels m in the sub scanning direction.
* M pixels, n and m are n <N and m <M with respect to the number N of main scanning pixels of the one-dimensional reading sensor 101 and the number M of main scanning pixel rows in the sub scanning direction. The size of n and m is a size including at least a plurality of character lines in a normal document even in a horizontally written document or a vertically written document.

FIG. 11A shows a state of a two-dimensional image cut out and temporarily stored in the image cutout memory. In the figure, the X direction is the hand scanner 10.
The Y-direction corresponds to the sub-scanning direction. Figure 1
Reference numeral 1 is a two-dimensional image image when a horizontally written document is vertically scanned. (The line direction is parallel to the X direction.) When a horizontal document is horizontally scanned, it is rotated 90 degrees to the right in the X and Y directions.
It becomes a three-dimensional image. (The row direction is perpendicular to the X direction)

Here, Kij = white or black i = 0,1 ,,, n-1: X direction position (main scanning direction) j = 0,1 ,,, m for each pixel Kij in the image cut-out memory 171. -1: Y direction position (sub scanning direction)

The row direction detection control unit 179 controls the address control unit 172 to cause the image cut-out memory 171 to output n pieces of {Kij} i = 0,1,2,, n-1 at a certain Y-direction position j. The X-direction pixel column (main scanning direction) including the pixels of (1) is read in pixel units and supplied to the black pixel number counting unit.

The black pixel number counting unit 173 counts the black pixels in the n pixels and stores the result in a predetermined position corresponding to j in the main scanning black pixel number change pattern memory 174. The row-direction detection control unit 179 detects the number of black pixels in each of the m X-direction pixel columns at the Y-direction position j = 0, 1, 2, ... The address control unit 172 is controlled. As a result, the main scanning black pixel number change pattern memory 1
The number of black pixels in the pixel row in the X direction is stored in 74 in order in the Y direction.

For (a) of FIG. 11, the change pattern of the number of black pixels as shown in (b) of FIG. 11 is stored.
Next, the row-direction control unit 179 causes the image cutout memory 171.
Change the reading order from to change {Kij} j at position i in X direction.
= 0, 1, 2, ..., m-1 Y-direction pixel column (sub-scanning direction) consisting of m pixels is read out in pixel units, and the black pixel number counting unit 172 is read.
The number of black pixels in the m number of pixels is counted and the result is stored in a predetermined position corresponding to i in the sub-scanning black pixel number change pattern memory 175.

In this way, the X-direction position i = 0,1,2,, n-
The n black pixel number counting result of 1 is stored in a predetermined position of the sub-scanning black pixel number change pattern memory 175.

For (a) of FIG. 11, the change pattern of black pixels as shown in (c) of FIG. 11 is stored. The change amount detection unit 176 first determines whether or not the change amount of the black pixel count value in the Y direction is equal to or more than a predetermined value and the number is equal to or more than a predetermined value based on the storage value of the main scanning black pixel number change pattern memory 174. To detect. Sub scanning black pixel number change pattern memory 1
Similar detection is performed for the stored value of 75.

Further, the periodicity detecting section 177 first determines whether or not the variation pattern of the black pixel count value in the Y direction is periodic, based on the stored value of the main scanning black pixel number variation pattern memory 174. , For example, by autocorrelation function calculation. The same detection is performed on the storage value of the sub-scanning black pixel number change pattern memory 175.

The row direction discriminating unit 178 is positive in the detection results of the change amount detecting unit 176 and the periodicity detecting unit 177 with respect to the stored value of the main scanning black pixel number change pattern memory 174, and the sub scanning black pixel number change pattern. If the detection results of the change amount detection unit 176 and the periodicity detection unit 177 with respect to the stored value of the memory 175 are not positive, it is determined that the row direction is the X direction (the main scanning direction of the hand scanner 10).

Further, the detection results of the change amount detection unit 176 and the periodicity detection unit 177 with respect to the stored value of the main scanning black pixel number change pattern memory 174 are not positive, and the sub scanning black pixel number change pattern memory 175 When both the detection results of the change amount detection unit 176 and the periodicity detection unit 177 with respect to the stored value are positive, it is determined that the row direction is the Y direction (the sub-scanning direction of the hand scanner 10).

With respect to the cut-out image image of FIG. 11A, the change pattern of the number of black pixels in the main scanning black pixel number change pattern memory 174 is as shown in FIG.
Since there are many places where the amount of change in the Y direction is large and the amount of change is large, and the periodicity of the change pattern can be detected simply, the detection results of both the amount of change detecting unit 176 and the periodicity detecting unit 177 are affirmative.

Conversely, the sub-scanning black pixel number change pattern memory 1
As shown in (c) of FIG. 11, the change pattern of the number of black pixels on 75 has a small change amount in the X direction and no periodicity is observed. Therefore, the detection results of the change amount detection unit 176 and the periodicity detection unit 177 are shown. Neither is positive. Therefore, FIG.
With respect to the cut-out image image of (a), the row direction determination result of the row direction determination unit 178 is the X direction (the main scanning direction of the hand scanner 10) from the detection results of the both.

By the above operation of the row direction detecting section 17,
Since the row direction can be detected from the image data read by the hand scanner 10, when the row direction detection result is the X direction (main scanning direction of the hand scanner 10), the hand scanner 1
0 can be discriminated as vertical scanning of the top and bottom of the document.
When the row direction detection result is the Y direction (the sub-scanning direction of the hand scanner 10), the hand scanner 10 can determine that the document has been horizontally scanned with respect to the top and bottom.

As described above, in the fourth embodiment, the sub-scanning direction with respect to the top and bottom of the document of the hand scanner 10 can be discriminated by the row direction detecting section 17, so
Similar to the second and third embodiments, when the sub-scanning direction is horizontal scanning, the read image can be rotated by 90 degrees to prevent the reproduced image from rotating by 90 degrees. In this embodiment, in order to detect the row direction, the number of black pixels in the pixel rows in the X direction and the Y direction is counted, but the same effect can be obtained by counting the black and white change points. You can

In addition, one rectangular area is cut out from the two-dimensional image of the read document to detect the line direction.
It is possible to further improve the detection accuracy in the row direction by cutting out a plurality of rectangular areas and finally determining the row direction based on the respective row direction detection results. However, although this solution is effective for a horizontally written document, it has an adverse effect for a vertically written document. However, it is effective for users who mainly write horizontal documents, or for specific users such as those in the Western world.

(Fifth Embodiment) Next, a fifth embodiment of the present invention is shown in FIG. In this embodiment, the hand scanner 1
For each read image read by multiple scans of 0,
In the case of vertical scanning, in which at least two read images, which are continuous in the scan order, have the same sub-scanning direction, these two read images are arranged on the left and right in the main scanning direction of electric transmission, and the print unit or a predetermined format is used. By electric transmission, the reproduced image is made substantially equal to the image of the read original, and the thermal paper is used more efficiently.

In order to achieve the above-mentioned object, this embodiment is the same as the first embodiment shown in FIGS. 1 and 2 except that each two-dimensional image of each two-dimensional image obtained by a plurality of scannings of a hand scanner is When the operation result of the scanning direction instruction switch 105 is two consecutive two-dimensional images in the scanning order,
A sub-scanning direction coincidence detection unit 18 for detecting whether or not they coincide with each other,
In addition to

When the detection result of the sub-scanning direction coincidence detecting section 18 is affirmative and the operation result of the sub-scanning direction instruction switch 105 is vertical scanning, the two consecutive two-dimensional image images preceding by the previous two are scanned. Main scanning pixel row {Pij i = 0,1,2,, N} at the sub-scanning position j of the two-dimensional image image and main scanning pixel row {Qij at the sub-scanning position j of the two-dimensional image image that follows in the scanning order. From i = 0,1,2,, N},

Let 2 (N + 1) pixel rows of [{Pij i = 0,1,2,, N}, {Qij i = 0,1,2,, N}] be new main scanning pixel rows. This is an embodiment configured by providing an image synthesizing unit 19. However, blocks having the same functions as those in FIGS. 1 and 2 are given the same numbers.

Next, the operation of the third embodiment will be described. In the description of this operation, the points different from the operation of the first embodiment will be described. Each read image read by a plurality of scans of the hand scanner 10 is encoded for information amount compression, and each encoded image information is encoded in each predetermined area of the encoded image information memory 3. Remembered in. The operation result of the sub-scanning direction instruction switch 105 is stored in each predetermined area of the sub-scanning direction instruction information memory 14 corresponding to each piece of encoded image information.

Here, in the scanning order, the coded image information of the read image by the R times of scanning (1), scan (2) to scan (R) and the sub-scanning direction instruction information are the coded image. It is assumed that they are stored in the information memory 3 and the sub-scanning direction instruction information memory 14. Prior to supplying or transmitting these read images to the printing unit 7, the sub-scanning direction coincidence detection unit 18 is provided.
Detects whether or not the scanning direction instruction information in each scan stored in the sub-scanning direction instruction information memory 14 matches at least two items which are consecutive in the scanning order.

When the scanning directions of scanning (1) and scanning (2) are different from each other, only the encoded image information of scanning (1) is independently encoded in the recording unit 7 or in the transmission image encoding. -Supply to the decoding unit 2. In this supply,
As in the case of the first embodiment, the coded image information is decoded by the hand scanner image decoding unit 12, the two-dimensional image image is reproduced on the two-dimensional image information memory 13, and the sub-scanning direction of the hand scanner 10 is obtained. In the case of vertical scanning, the main scanning direction of the hand scanner 10 is supplied in the main scanning direction of electric transmission, and the sub-scanning direction is supplied in the sub-scanning direction of electric transmission.

When the sub-scanning direction of the hand scanner 10 is horizontal scanning, the 90-degree coordinate conversion unit 15 performs 90-degree coordinate conversion and supplies the converted two-dimensional image image. When the scanning directions of the scanning (1) and the scanning (2) coincide with each other and the scanning direction is the horizontal scanning, only the encoded image information of the scanning (1) is processed in the same manner as the above horizontal scanning. Then, the two-dimensional image image after the 90-degree coordinate conversion is supplied to the recording unit 7 or the transmission image encoding / decoding unit 2.

When the scanning directions of the scanning (1) and the scanning (2) coincide with each other and the scanning direction is the vertical scanning, the image synthesizing unit 19 performs the scanning (1) and the scanning (2) as follows. The images are combined, and the combined result is supplied to the recording unit 7 or the transmission image encoding / decoding unit that encodes for transmission.

Here, the two-dimensional image image decoded by the hand scanner image decoding unit 12 in the scanning (1) is moved to the position in the scanner main scanning direction as shown in FIG.
i, the decoded pixel at position j in the sub-scanning direction is {Pij}, and the decoded two-dimensional image image of scanning (2) is shown in FIG. The decoded pixel at the direction position j is {Qij}.

The image synthesizing unit 19 first expands / reproduces the decoding result of the coded image information of scanning (1) by the hand scanner image decoding unit 12 on the two-dimensional image information memory 13. Subsequently, the decoding result of the hand scanner image decoding unit 12 of the encoded image information of scanning (2) is expanded and reproduced on the two-dimensional image information memory 13.

The development / reproduction position of the decoding result of this scan (2) on the two-dimensional image information memory 13 is, as shown in FIG. 17, scanned (scanned) in the main scanning direction (from left to right). Expand and reproduce so that it is located on the right side of 1).

That is, the main scanning pixel column {Qij i = 0,1,2,, N} at the sub-scanning position j in scanning (2) is the main scanning pixel column {Qij i = 0,1,2,, N} at the sub-scanning position j in scanning (1). Pij i = 0,1,2, ..., N} is developed and reproduced so as to be located on the right side. A white pixel row {W0j, W1j} is inserted between the two main scanning pixel rows.

This white pixel row is inserted by the above scanning (1).
And the scan (2) are combined so that the main-scanning pixel rows at the sub-scanning positions j of both are aligned in one row, the sub-scanning start positions of both hand scanners 10 are equidistant from the top position of the document. If this is not the case, the composition result will be different in the vertical direction of both, and if the pixels at the ends of both are adjacent, it will be rather difficult to see, so to avoid this,
The purpose is to avoid this by leaving a space between the two. Here, the width of this margin is set to two pixels for convenience of description, but may be appropriate.

In this way, the system controller 8 controls the sub-scanning position for the two-dimensional image image developed and synthesized on the two-dimensional image information memory 13 by the image synthesizer 19.
Main scan pixel column of scan (1) of j {Pij i = 0,1,2,, N}
And a white pixel column {W0j, W1j} and a main scanning pixel column {Qij i = 0,1,2 ,,, N} of scanning (2), totaling (N + 1) +2+ (N + 1). This pixel row is set as a new main-scanning pixel row, and the new main-scanning pixel row is arranged in the recording section 7 in the order of the sub-scanning position j (j = 0, 1, 2, ..., M).
Alternatively, it is supplied to the transmission encoding / decoding unit.

Here, the combination of the two images of scanning (1) and scanning (2) has been described, but the number of images to be combined into one is not limited to this, and the recording unit 7 or the electronic device may be used. Allowable value of the number of main scanning pixels (for example, 2048 pixels)
Multiple images can be combined within a range that does not exceed.

For example, the allowable value of the number of main scanning pixels on electric transmission is 2048, and the number of main scanning pixels of the hand scanner 10 is 5.
With 12 pixels, 3 or 4 scanned images can be combined and transmitted. When the three scan images are combined, they may be arranged in the scanning order in the main scanning direction from left to right in the same manner as described above.

FIG. 18 shows a state of a reproduced image when one read original is scanned by the hand scanner 10 twice.
