Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing apparatus and an image reproducing method for performing image processing on an electrically read original image recorded in a recording medium and reproducing the image.

[0002]

2. Description of the Related Art Conventionally, an original image electrically read by a scanner is accumulated and recorded in a magneto-optical disk,
An image reproducing apparatus has been put into practical use, which retrieves and reproduces a document image when necessary, displays it on a display device, and prints it out by a printer device.

Original images handled by these image reproducing apparatuses are generally read by using a white outline as a background. Therefore, when the original image is displayed or printed out during playback, if the external dimensions of the original image are smaller than the display screen area of the display and the size of the output medium such as recording paper for print output, the character image will be displayed. It becomes to float in the air against the background (the original image 20 in FIG.
4)), the image information is difficult to see and the boundary between the original and the background is not known, which may cause a problem.

In order to solve this drawback, a method has been proposed in which a black background is added to the periphery of the original image, and the image is read and recorded. According to this method, the size information of the document image can be added as part of the image at the time of reading, which is an effective means for solving the above problem.

However, when this image is reproduced and used at the time of reproduction, there is no particular inconvenience for displaying the original image on the display, but when this is used for print output, it is as follows. Inconvenience occurs. That is, since solid black partial pixels added around the original image are printed out as they are, when the size of the reproduced original image is smaller than that of the print paper, the ink or toner of the printer is not used. A large amount of waste is consumed, and at the same time, a new problem arises in that the inside of the apparatus is significantly contaminated due to scattering of useless ink or toner.

In order to solve this new problem,
When searching for a document image stored and recorded in the recording medium, playing it back, and printing it (this may be displayed, of course), the boundary line between the document image and the surrounding black background part is detected, and its outer periphery is detected. An image frame addition process that leaves only the original size information as an image frame by converting only the part as a thin line and converting the outside part to match the background color (generally white) of the document Later, it is known that a method of outputting a document image to a printer device is effective.

As a method of performing the image frame adding process at high speed, the image data read from the recording medium is once converted into a 1-bit black and white pixel column, and the pixel data is sequentially synchronized with the transfer clock. A method has been put into practical use in which an image frame is formed by processing, and one or more processed original images are temporarily stored in a page memory, and then displayed and printed out.

[0008]

However, when the image frame adding process is uniformly applied to all original images, for example, the original image to be reproduced and the print sheet for print output are used. If the originals are of the same size and the original is misaligned or skewed when the original image is read, only part of the original image frame of the original image is added to the print paper as shown in FIG. This may adversely affect the original document by emphasizing the deviation of the original document.

As a method for solving this drawback, conventionally, as an additional function of the image frame processing, an image frame erasing process for converting all black background portions outside the original document into the background color of the original image is provided to read the original image. After (see FIG. 13 (a)), 2
The binarization process is performed (see FIG. 13B), and if necessary, the operator adds the image frame addition process mode (see FIG. 13C) and the image frame deletion process mode (see FIG. 13D). This is dealt with by making it possible to select either or.

However, according to this method, a large number of original images of various sizes are continuously read out from the recording medium, and the optimum image frame processing is applied to each original (that is, the originals which are almost the same as the print paper). When the image frame is erased for an image and the image frame is added for a small original image), and the print output is attempted, the work efficiency is significantly deteriorated, which is not practical. .

In view of the above conventional problems, the present invention continuously reads out a large number of original images of various sizes, and automatically performs optimum image frame processing on each original without operator intervention.

Specifically, it is composed of a document width detection circuit (FIG. 6) and a document length detection circuit (FIG. 7) described later. The image frame processing means 15 uses the fact that the background color of the reproduced image signal is different, so that the image frame processing for adding or deleting an image frame to the reproduced document image by high-speed sequential processing is performed. Give. Specifically, it is composed of an image frame processing circuit (FIG. 4) described later.

A document image temporary storage means 16 is connected to the output side of the image frame processing means 15. The document image temporary storage unit 16 is a storage unit configured by a semiconductor memory device or the like for temporarily storing one or more image frame-processed document images subjected to image frame processing. A document size / paper size comparison unit 17 is connected to the output side of the document image outer shape detection unit 14. The original size / paper size comparison means 17 obtains the external dimension information of the target original document currently being processed by the original image external shape detection means 14, obtains the print paper information currently set, and outputs both information. Compare.

On the output side of the document image temporary storage means 16, an image display means composed of a CRT or a liquid crystal display for displaying the document image stored in the document image temporary storage means 16 on a monitor. 18 is also connected to an image print output means 19 which is composed of an LBP (laser beam printer) or the like for printing out a stored original image on a print sheet.

Next, using the flow chart shown in FIG.
Characteristic operations up to print output in the image reproducing apparatus of the present embodiment configured as described above will be described.

First, in step S1, the original image is read out from the recording medium and temporarily stored in the original image temporary storage means 16, and in the following step S2, the external dimensions of the original are determined by utilizing the fact that the background portion is black. It is detected by the outer shape detecting means 14. Then, in step S3, the external size information of the original image obtained by the external shape detection unit 14 and the external size information of the currently selected print paper are used, and the original size / paper size comparison unit 17 compares the two information. I do. As a result, if the original image size is substantially equal to or larger than the print paper size, the image frame processing means 15 is instructed to select the image frame erasing processing mode (step S4), and then the printing is performed. Output processing is executed (step S5).

If the original image size is smaller than the print paper size, the user is instructed to select the image frame addition processing mode (step S6), and then the image centering processing and print mode are selected (step S6). S
7) In step S5, print output processing is executed.

As described above, by providing the mode automatic selection means by the outer shape detection means 14 and the document size / paper size comparison means 17, one example is shown in FIGS. 3 (a) and 3 (b). (A) shows the case where the image frame erasing mode is selected, and (b) shows the time when the image frame adding mode is selected), when the continuous printing process is performed in the state where the originals of various sizes are mixed. Also in this case, it is possible to automatically perform the optimum image frame processing on each document and then print out the print paper.

Next, the image frame processing operation actually performed by the image frame processing means 15 will be described in detail with reference to FIG. 4 is a circuit diagram showing the configuration of the image frame processing circuit that constitutes the image frame processing means 15. As shown in FIG.

The basic operation of this image frame processing circuit is to successively generate an effective pixel section signal as shown in FIG. 4 for the main scanning line currently being read, and to make this signal effective immediately before the document width. Then, by making it invalid immediately after the document width (the image signal is forcibly converted to a white level in the invalid section), a black background of several dots width is left on the front and back (left and right) sides of the document. This forms a picture frame.

In reality, however, the image frame processing template shown in FIG. 5 cannot be formed in the FIFO (first in first out) memory because the image frames on the top and bottom sides of the document cannot be formed only by the evaluation in one main scanning line. By using, it is possible to add image frames not only to the left and right sides but also to the top and bottom sides.

In FIG. 5, four pixels (black circles in the figure) arranged at four corners around the target pixel (currently outputting pixel) position
Is the evaluation point, and all 4 pixels are white (or black)
If so, give a white (or black) rating to each point.

When the image frame adding process is performed using this evaluation plate, when a white evaluation is given to any of the evaluation points (see FIG. 6A), the effective pixel for the target pixel is determined. When a section is validly started and black is given to all four places (see FIG. 6B), the section is validly ended, and a black color with a vertical width of 2 dots and a horizontal width of 3 dots is provided around the original. The background is left as a black frame of the original.

On the other hand, in the case of performing the image frame erasing process, when the white evaluation is given to all of the four evaluation points at the four corners (see FIG. 6C), the effective pixel section is set. When the validity is started and black is given to any of four places (see FIG. 6D), the validity is ended so that the top and bottom are 2 dots wide and the left and right 3 dots are wide within the valid range of the document. The minute range is the effective pixel section, and as a result, the surrounding black background portion is completely erased (converted to white).

Next, the specific operation of the image frame processing circuit shown in FIG. 4 will be described in detail.

The 16-bit counter 601 is cleared by a horizontal (line) synchronizing pulse (HSYNC bar) which is a start pulse for one line of main scanning of an original image,
Furthermore, since the pixel clock (CLK) is applied as a clock input, the current data position of one line is always incremented and shown as the count output value of the counter 601.

On the other hand, SR latch 602 which is a latch circuit
Output becomes "0" by the clock dot group sense signal (SNSBK bar), and the white dot group sense signal (SN
It becomes "1" by the SWT bar). This SR latch 60
The output of 2 is a D-type flip-flop circuit (hereinafter,
16-bit flip-flop 60 after being resynchronized with the pixel clock CLK by 603)
4 is input to the clock terminal CK.

On the other hand, the 16-bit flip-flop 60
Since the count output value which is constantly incremented is given to the sampling data group terminal [D] of 4, the count output value of the final white position of the current line is stored in the output. . Further, at the clock terminal CK of the 16-bit flip-flop 605 at the next stage,
Since the horizontal sync pulse (HSYNC) of positive logic is input, the count value of the minimum white position of the previous line is stored at the output terminal [D] of the 16-bit flip-flop 605 at the beginning of the next line.

In the next line, the 1-line start delay output signal generated by the SR latch 607 and the DFF 608 by the output of the first white dot group sense signal (SNSWT bar) is already in the valid state ("0" in the previous line). The output of the SR latch 609 is the sense signal (SNSWT bar) of the first white dot group described above.
Is enabled (“0” level).

On the other hand, the 16-bit comparator 60
A count value corresponding to the constantly incremented current data position is input to the input terminal group [Q] of No. 6 and the other input terminal group [P] of the comparator 506 is described above. The count value corresponding to the final white position of the preceding line is held and input. Therefore, the current data position is sequentially incremented and updated, and when the two values match, the "0" level is output to the match output terminal (P = Q bar) of the comparator. As a result, the output of the SR latch 609 returns to the invalid state (“1” level).

That is, the output of the SR latch 609 becomes valid (“0” level) when it reaches the sense position of the first white dot group of the scan line, and the last white dot of the immediately previous scan line stored. By returning to the invalid state (“1” level) at the sense position of the group, it becomes possible to generate an effective pixel section signal for the image frame processing within the one scanning line.

This effective pixel section signal and the pixel data of interest (CURID) are filtered by the filter gate 601 to the negative logic A
The image frame processing function described above is realized by taking the ND (logical product) operation.

Next, the specific operation of the document image outer shape detecting means 14 shown in FIGS. 7 and 8 will be described. 7 is a circuit diagram showing the configuration of the document width detection circuit, and FIG. 8 is a circuit diagram showing the configuration of the document length detection circuit.

In FIG. 6, reference numeral 701 denotes a 16-bit comparator having P <Q bar terminals, and 702 and 703.
Are 16-bit flip-flops, and 704 is a 16-bit comparator having a P> Q bar terminal.
The flip-flops 702 and 703 are respectively FFFF (hexadecimal) and 0000 (16) in response to a vertical (page) synchronizing pulse (VSYNC bar) which is a start pulse of the original.
It is initially set to a decimal number.

The current data position of the original line generated by the 16-bit counter 601 shown in FIG. 4 is input to the input terminal group [P] of the comparators 701 and 702.
On the other hand, the white dot group sense signal (SNSWT bar) generated by the evaluation plate shown in FIG. 5 is input to the gate output enable terminal [G] of each of the comparators 701 and 702.

Therefore, when the first white dot group in the original is detected, P <Q of the comparators 701 and 702.
Low pulse is output to the bar terminal and P> Q bar terminal,
The current data position at that time is the flip-flop 70.
2, 703 are stored in the respective output terminal groups [Q].

Thereafter, the comparator 701 determines that the current data position is smaller (that is, the white position on the left side of the document).
Is detected, the value of the output group [Q] of the flip-flop 702 is updated, while the comparator 703 detects that a larger current data position (that is, a white position on the right side of the document) is detected. 704
The value of the output group [Q] is updated. As a result,
After the reading of one page of the manuscript is completed, M
By reading the final output values of the flip-flops 701 and 702 via the input ports 705 and 706 connected to the PU (microprocessor unit) bus, it becomes possible to obtain the left and right positions of the document, that is, the maximum document width. (See Figure 9).

In FIG. 8, a 16-bit counter 801
It is possible to obtain the document length by counting the number of horizontal synchronizing pulses (HSYNC bar) in the page section signal (PAGE bar) and reading the final output value via the input port 806.

On the other hand, if necessary, the final line position in which the white dot group held by the 16-bit flip-flop 803 is detected is read out via the input port 807 to obtain the rear end position of the document. be able to. Further, the first white dot group detection low pulse created using the flip-flop 804 is made to act as a clock, and 1
The leading edge position of the document can be obtained by reading out the leading line position where the white dot group held in the 6-bit flip-flop 805 is detected via the input port 808.

As described above, in the first embodiment, the size of the original image to be reproduced is detected by utilizing the fact that the black background is added to the original image read from the recording medium and reproduced. The size information of the currently selected print paper is compared with the size information of the detected original image. According to the comparison result, if both information are substantially equal to each other or if the document image has a larger vertical / horizontal dimension, the image frame erasing means is caused to act, and if not, an automatic frame selecting means is actuated. Since it is provided, when the document images of various sizes are output on the print paper selected by the operator in advance, it is possible to automatically operate the optimum image frame processing for each document size and print out. As a result, when the original size and the print paper size are almost the same, the image frame erasing processing mode is automatically selected and unnecessary image frame fineness is caused due to slight misalignment between the reproduced document and the print paper. It is possible to prevent the image from being generated in the image and making the image uncomfortable.

Further, when the document size is smaller than the print paper size, the image frame addition processing mode is automatically selected, and the centering process is further automatically performed to print out, so that the size information of the document is left. Is possible.

Next, a second embodiment of the present invention will be described.

The basic construction of the second embodiment is the same as the first embodiment.
It is the same as the embodiment, and the only difference is that the image print output unit 19 can select a plurality of types of paper sizes.

Next, the characteristic operation up to print output in the image reproducing apparatus of this embodiment will be described using the flowchart shown in FIG.

First, in step S11, the original image is read out from the recording medium and temporarily stored in the original image temporary storage means 16, and in the following step S12, the outer dimension of the original is determined by utilizing the black background portion. Outer shape detecting means 14
Detected by Then, in step S13, the original size information of the original image obtained by using the original image external shape detection unit 14 and the external size information of a plurality of types of sheets selectable by the image print output unit 19 are used. The size / paper size comparison means 17 compares sizes.

If there is a document size that is substantially the same as the original size among a plurality of selectable paper sizes, the image frame processing means 15 is instructed to select the image frame erasing processing mode, and the image is centered. A process and a print mode are selected (step S15), and the print output without the image frame is performed using the above-mentioned substantially equal sheets (step S16).
If there is no paper of substantially equal size, it is determined whether a paper size larger than the original size can be used (step S17), and if possible, the image frame addition processing mode is set to the image frame processing means 15. A selection is instructed (step S18), and printout with an image frame is performed using the larger paper (step S16).

When a print sheet that matches any of the above cannot be selected, it is necessary to select a suitable image frame processing mode and a print sheet to be output, for example, by executing a predesignated means. (Step S19). The simplest method is to interrupt the print output at that point and have the operator intervene to select the appropriate mode.However, this method allows multiple originals to be printed continuously at once. In such a case, if the operator is absent, the print output process will be interrupted for a long time in the middle, which is inappropriate for some purposes.

In this case, for example, after selecting the print paper having the size closest to the outer dimensions of the original, selecting the image frame erasing processing mode, and performing the reduction processing of the original image based on the size information of both information. The printout can be automated, and the printout process can be continued without operator intervention.

As described above, in the second embodiment, the size of the original image read out from the recording medium and reproduced is detected, and the size information of the detected original image and a plurality of types of print papers currently usable are detected. The size information is compared with the result of the comparison, and it is determined whether or not there are print sheets of substantially the same size. When the vertical / horizontal dimensions of all the print papers are smaller than the original image, the image frame erasing means is operated, and papers of almost the same size are used (if all the papers are small, the largest size among them is used). Select) Print out. If the original image has a smaller vertical / horizontal dimension than all the print sheets, the image frame adding means is operated to at least make the print sheet of an appropriate size in which the image frame of the added original is not missing. Use to print out. In this way, it is possible to combine the image frame processing function and the print paper selection function to automatically operate and print out.

Further, as described in the first embodiment,
When the image frame addition means is selected and a document image is printed out on a print paper of a larger size, a centering function is also provided and this is operated at the same time to prevent the image frame from being missing. It is possible to prevent and provide the size information of the reproduced document image more effectively.

Next, a third embodiment of the present invention will be described.

The basic structure of the image reproducing apparatus of the present embodiment is the same as that of the first and second embodiments, and the only difference is the image rotating means (90 degrees or 270 degrees) for rotating the reproduced image. It is the point where is added.

Next, the characteristic operation up to print output in the image reproducing apparatus of this embodiment will be described using the flowchart shown in FIG.

First, in step S21, the original image is read out from the recording medium and temporarily stored in the original image temporary storage means 16, and in the following step S22, the external dimensions of the original are determined by utilizing the fact that the background portion is black. Outer shape detecting means 14
Detected by Then, in step S23, the document size / paper size comparison means 17 compares the document size with the paper size (step S23). If the results do not match, then the vertical dimension of the document and the lateral dimension of the paper are compared with each other, and the lateral dimension of the document and the vertical dimension of the paper are compared (steps S24 and S25), and when both information are substantially the same. In addition to selecting and operating the image frame erasing processing mode (step S26), the image rotating means is operated (step S27) and then printed out (step S27).
28). This makes it possible to deal with a document image read by rotating it by 90 degrees or 270 degrees.

In the present embodiment, even when the original is stored and recorded on the recording medium in the state of being rotated by 90 degrees (or 270 degrees), it is possible to automatically detect it at the time of reproduction and rotate it to print out. To do.

The present invention is not limited to the illustrated embodiment, and various modifications can be made. That is, in each of the above-described embodiments, the effectiveness regarding the image frame processing and the print output has been mainly described. However, in addition to this, for example, when a reproduced document is displayed on the display, it is automatically displayed in the upper left corner reference, Various applications are possible by utilizing only the fact that the original has a black background, such as displaying the original by reducing it at an appropriate reduction ratio so that the entire original can be inserted into the effective display area without being chipped.

As described in detail above, according to the image reproducing apparatus and the image reproducing method of the present invention, when the original images of various sizes are output on the print paper selected by the operator in advance, In addition to automatically outputting the optimum image frame processing for each size to print out, there are the following effects.

(1) For example, when the image frame adding means is selected and a document image is printed out on a print paper of a larger size, a centering function is also prepared and they are simultaneously operated. If the center of the original image and the center of the print paper are matched and the print output is performed, it is possible to prevent the loss of the image frame and the like, and more effectively provide the size information of the reproduced original image.

(2) Since the external dimension information of the original required for automation is automatically generated at the time of reproduction by utilizing the fact that the background of the original is black, it is intended for the purpose of preventing image show-through, for example. Therefore, the present invention can be applied to a document image or the like read with a black background, and thus can be applied in a wide range.

(3) Since it is possible to automatically output a group of originals of various sizes on a print sheet of the same size in an optimum state, the reproduced originals that have been printed out are again filed on a binder or the like. It enables the optimum print output form for the purpose of reuse.

Further, in the sixth and thirteenth inventions, it is impossible to automatically select the printing paper collectively and print out various size originals using the same paper as the original size as much as possible. Only when it is, printout is performed with the image frame information left on a large size print paper, so it is possible to create the optimum printout form for the purpose of distributing the reproduced original printed out as a copy of the original in the recording medium. Becomes

Further, in the seventh and fourteenth inventions, even when the original is stored and recorded on the recording medium in a state of being rotated by 90 degrees (or 270 degrees), it is automatically detected at the time of reproduction and rotated to print. It is possible to output.
