Abstract

PURPOSE:To synthesize a picture and a character including an additional word with high quality by generating a picture file in which the additional word is already arranged based on the picture file and the additional word file and synthesizing the picture file and the text file. CONSTITUTION:A character input device 204 or a keyboard inputs a text in an original 301 as a character data represented in a code together with position information of the picture to generate a text file 302. Moreover, the additional word data is formed as a character data represented in a code to generate the additional word file 304 and the picture file 303. The additional word file and the picture file are displayed on a display device 211 to generate a 2nd picture file 305 in which the additional word is already arranged. The 2nd picture file and the text file are synthesized to generate an output file 306. The optical output device synthesizes the character, picture and additional word onto one photosensitive member and gives an output based on the output file.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides an optical output device that outputs characters and images created as separate data at desired positions on a single photosensitive material with quality suitable for each. The present invention relates to a method for synthesizing characters and images that can be output using the following methods.

[Background Art of the Invention] Conventionally, when creating a copy of a printed matter containing a mixture of text and images, the text and image data were input separately, edited and proofread, and the position information, etc. when combined, was input. In addition,
Text and images were output on one output device to create the desired block copy. An example of such a device is shown in FIG. 7, for example.

In the example shown in FIG. 7, characters are first read from an input device 702 and images are read from a scanner 703 based on a document 701. The character data is filed in the text file 704 together with the position information of the image on the photosensitive material serving as the output medium, and the image data is filed in the image file 7O5. Both are combined into a composite file 706 and sent to an optical output device 707.
, for example, by a laser beam printer. In this way, a composite image of characters and images was created and used as a base for the desired printed material, but many problems have been pointed out.

[Problems with the prior art] When a text (hereinafter referred to as the main text), which is a collection of characters, and an image are combined and placed on one page, explanatory terms and phrases for the image are provided along with the image (hereinafter referred to as "main text"). are often called adjuncts). The position of this additional word cannot be determined unless the position of the text or image on the cutlery is clear, and it is always treated as one with the image, so even though it is originally text data, it is integrated with the image. You must use a scanner to capture it as a genuine document. It is also possible to use a method of pasting additional words created in advance on the photosensitive material on which the image has been output as explanatory terms and phrases for the image, but this requires complicated work.

As the content of printed matter, which consists of text data including additional words and various image data, becomes more sophisticated and complex, the amount of data to be handled increases, and the positioning and layout of each item in the appropriate position, Not only does the compositing work, such as selecting the magnification of the reproduced image, become complicated, but it also causes quality problems.

For example, in order to reproduce character data with a laser beam printer, it is common to develop the character data into a -H pit map and scan the data by turning the beam on and off based on the result. However, depending on the scanning density of the beam, jagged edges may appear in the outline of the characters, and if the image side is also scanned with a beam diameter, light intensity, etc. suitable for reproducing character data, the quality of the image side will deteriorate. Conversely, if the text side is scanned using the beam characteristics on the image side, the quality of the text will deteriorate.

[Means for Solving the Problems] The present invention aims to provide a composition method that can easily compose and output even printed matter that is a complex mixture of text data, image data, additional word data, etc. In particular, it is possible to easily and freely arrange the position and size of images even for items that require troublesome processing such as additions. By treating it as a character code in the same way, it is possible to process it without being affected by quality deterioration due to scanner reading or the characteristics of the light beam of the output device due to being treated as an image even though it is a character. The purpose is to

In order to achieve such an object, the present invention provides a method for synthesizing text and images, in which text and images are transferred to an optical output device via a display device, and are synthesized and output on a single sensitive material. , a text file F1 containing character data representing each of the input characters as a code and positional information where the image is output on the photosensitive material; data of the input image and size information when outputting this image data; An image file F2 containing the above-mentioned li! and an additional class file E3 containing additional word data input separately from the character data and representing each character as a code are created, and the above-mentioned li! Desired data is successively outputted from the i-image file F2 and displayed on the display device, and the desired additional class read from the additional class file F3 is placed using an arbitrary point in this displayed image as the origin, and its placement position information is added. Create a second image file F4 with additional words arranged, and combine the second image file F4 and the main text file F.
1 is synthesized to create an output file F5, and the character data read from the output file F5 is read out from the character generation section of the optical output device according to its character code, and the combination processing specified by the character data is performed. information on the photosensitive material, the image data outputs the corresponding desired image data on the photosensitive material based on the output position information in the text data, and the additional word data outputs the corresponding additional class according to its character code. , read from the character generation section of the optical output device and output it on the photosensitive material according to the combination processing information;
The main feature is that character data, image data, and additional word data are synthesized on one photosensitive material.

[Embodiment of R-light] Images in the present invention include binary images without halftones, such as line drawings, and multivalued images with halftones, such as photographs, but do not include characters. However, when referring to an image that is a composite of text and images, the latter image includes text.

First, the outline of the method for synthesizing characters and images according to the present invention will be explained based on the example shown in chart 70 of FIG. After inputting the manuscript and layout instructions [1], if the manuscript to be input is a main text [2], it is input in the form of a code using a character input device [3]. Next, to the input text data, add or add image position information, the length of one line of text,
A composing process is performed to instruct the composing style such as the size of each character, lu coarseness, horizontal writing, type of font, etc. [4]. A text file is created using the assembled text data [5].

When the original is an image [6], import the image with a scanner [7J0 Name each imported image data and combine multiple images into one file [8]
. At this time, also add the vertical and horizontal dimensions when outputting the image.

Togi [9] whose manuscript is an additional type is input from the character input device in the same way as the main text [1o]. When inputting data, name each unit of addition class and create an addition Sri file [11
1゜Thus, image file [8] and additional class file [11]
Once you have all the information, place the additions using the display device [
12]. Once you have finished placing the adjuncts, add the second adjunct
Create an image file [13].

Once the image file with additional edicts is created, merge it with the main text file [14] to create one output file,
Make the data acceptable to the output device. Based on this data, text, images, and additional information are output on the same sensitive material using an optical output device, such as a raster laser beam printer or a CRT ([15]).

FIG. 2 shows an example of an apparatus most suitable for carrying out such a method of synthesizing characters and images. In this figure, a CPU (central itch unit) 201 performs control and calculations of the entire device according to a program stored in a memory 202.

Data is input using a scanner 203, a character input device 204, and a combination processing information input device 205. The input character data, image data, and combination processing data are sent to the CP via interfaces 206, 207 and 208.
Sent to U201. The input data is once transferred to the memory 202, then sent to the console 209, where a data name, file name, etc. are added, and sequentially sent to the magnetic disk 210 where it is stored.

When a command is given to display a desired image on the display unit 215 by operating the keyboard 213, mouse 214, etc. connected to the display control unit 212 of the display device 211, the CPLJ 201
is the image file F stored on the magnetic disk 210
2 and sends the image data back to the display control section 212. Display control section 2
12 displays an image on the display section 215 according to the sent image data.

When a command is given from the keyboard 213 or mouse 214 to display a desired text on the display device 211, the display control unit 2
12 transmits the command to the CPU 201, which reads the desired text from the text file F1 on the magnetic disk and sends the data to the display control unit 212. The display control section 212 requests that the character code of the character data be read out from the character font memory of the display character generation section 216 and converted into the data developed in the pit map memory. According to the request, the display character generation unit 216
The display control unit 212 displays the main text on the display unit 215 based on the character data sent back from the display unit 215 .

Further, the display device 211 can also input text data from the keyboard 213, and proofreading and 1I7i bundling are performed while viewing the text displayed on the display unit as described above.

When a command is given from the keyboard 212 or mouse 213 to arrange and display a desired additional layer on an image, the display control unit 212
transmits the command to the CPU 201, and the CPU 201 searches for the desired additional layer from the additional layer file F3 of the magnetic disk 210, sends the additional word data back to the display control section 212, and also sends the additional word data to the display character generation section 216. Send data. Display control 11i! l11212 requests to convert the sent data into data developed in the bitmap memory, and in accordance with the request, the character generator 216
The character data sent from the font memory of the font is displayed at the desired position of the displayed image. When placing an additional layer in a display image, various image processing is performed in the display unit @211 as described later, and the calculations are also performed by CPLJ.
201 will do it.

The second image file F4 to which the additional layer arrangement position information has been added in this manner is stored on the -H magnetic disk 210.

The second image file F4, in which the additional layer has been placed, is merged with the main text data to form an output file F5. The output file is stored on the -H magnetic disk 210 and the CP
It is transferred to the optical output device 218 via the interface 217 under the control of U201. Output device 218
The receiver records the data on the sensitive material by, for example, raster scanning a light beam in accordance with the data of the output file.

At that time, if it is character data, the output character generation unit 219
A request is made to convert the character code into character data developed in the dot map memory, and in accordance with that request, the light beam is turned on and off using the character data sent back from the font memory. If the data to be output is image data, the output device 218 converts the data into a raster image and controls the on/off of the light beam according to the image data.

FIG. 3 is a diagram illustrating the process of composing the second image file F4 and the text file F1, which are sent to the output device 218, by combining the conventional example shown in FIG. 7. The manuscript 301 includes a main text, an image, additional layer characters and images, and layout information thereof. The main text and additional layer are input using the character input device 204 or the keyboard 213, and image position information is added to form the main text file 302. Image is from scanner 203
is input as image data by
The additional layer input from the input device fi 204, which constitutes the additional layer file 304, constitutes the additional layer file 304.

The image file 303 and additional layer file 304 are both transferred to the display device 211, additional layers are arranged, and a second image file 305 in which additional words have been arranged is created. The second image file 305 is merged with the main text file 302 to create a final output file 306, and the data is sent to the output device 218.

FIG. 16 shows an example of a cutlery most suitable for outputting by such a method of combining characters and images.

1601 is the entire dekamono that will be used as a block copy, and 160 is represented by a line.
2 is the output of the main text. 1603 indicates an image, inside which an additional layer 1604 is attached.

The contents of each file shown in Figure 3 are shown in Figures 4 and 5.
This will be explained in detail with reference to the drawings and FIG.

First, 302 in FIG. 4 shows an example of the text file F1. A file label a identifying the name of the file is set at the beginning of the file.

Next, data ro and b are provided for distinguishing between characters and images and other data contents. Next, data C representing combination processing information is input. This data includes information that specifies the output size for one page, data length that indicates how much data there is, character size, font, character spacing, line spacing, and various layout information on the cutlery. be. Then, character data d is recorded in the form of a code.

The space information e is position information where the image is output on the photosensitive material, and the characters represent areas that cannot be output. Although omitted in the figure, a data end code indicating the end of the data is attached to the end of the data.

A necessary number of text data as described above is collected to form one text file F1.

303 in FIG. 4 illustrates the image file F2. File label, image data IO, then i[ii1
The name f is coming. The image base is the index by which the image is recalled to the display for placing additional layers. The output size 9 that comes after the image base represents the size of the image on the cutting tool. Then, image data h is recorded, and when one image data ends, a data end code i is recorded to distinguish it from the next data.

Similarly, the additional layer file 304 also includes the file label, data ID, name of the additional layer, and combined processing data (character size,
Character data j is recorded in the form of a code after the font (...).

305 in FIG. 5 is a second image file F4 in which additional words have been placed, which is created by placing an additional layer on the image. The image data end code i is followed by the data ID of the additional layer, data k indicating the arrangement position of the additional layer is added, and then the combination processing data and the character code j constituting the additional layer are recorded. .

FIG. 6 shows an output file F5 obtained by merging the main text file F1 and the second image file F4 of FIG. @The main text data comes first. For this purpose, the main text data includes information about itself, the image, and the size of the cutlery that outputs the additional layer in the processing data.

A space e in the middle of the text data is position information for outputting the image. When this position information is detected, the commanded image is searched, and the predetermined output size Q,
The image data is output.

When data of an additional layer accompanying the image is detected following the end of the data of one image i, the character data is read from the character font memory of the output character generation unit 219 in FIG. 2 and arranged. Recorded at the location specified in the location data. The output file F5 is configured as described above, and an end code is finally recorded to end the file.

Next, a description will be given of how to arrange the additional layer using the table in FIG. 2 and the water device 211.

FIG. 8 shows a display example of the display screen of the display section 215, where 801 is the entire display screen, 802 is the main display section, and 801 is the entire display screen.
03 is a menu display section. The main display section displays the read text data, image data, and additional word data, and the menu display section 803 displays various data, the operating status of the display section 215, messages from the CPLJ 201, and the like.

804 represents the currently displayed image base and additional word base.

805 is a part of the monitor which will be explained later.

Image display on the main display section 802 includes an entire surface water mode and a partial display mode. The entire display mode is a mode in which the entire image is displayed, and the partial display mode is a mode in which one part of the image is enlarged and displayed.

First, the case of full display will be explained based on FIGS. 9 and 10.

FIG. 9 is an example of an image manuscript 9o showing a part of a work illustration. Vo, Ho output this image RIi221
The output size when outputting at 8 corresponds to 9 in Figure 4 303, and the image scanner 203 console 209 when manually operated
Enter from. FIG. 10 is an image in which an additional ff 1100 is arranged on the image of the document 90 in FIG. 9 displayed entirely on the main display section 802, and the size is VA, H8. Display section 2
The ranges vM and HM in which an image can be displayed on the main display section 802 (FIG. 8) of No. 15 are determined mechanically, so it is not always possible to display the image in the same size as when it is output by the output device 218. As a result, some of the additional words displayed may be small and difficult to read, or it may be difficult to determine whether the font, size, etc. match what you have specified. In such a case, partial display as shown in FIG. 11 is a method of enlarging and displaying a part of the image that is being displayed as a whole. In this example, the left center portion of the image in FIG. 10 is partially displayed. Ve and Ha are the vertical and horizontal dimensions of the partially displayed range. This Ve, He is the whole @VA, I
The part of the monitor 805 in FIG. 8 indicates which part of the -IA corresponds.

FIG. 12 explains the flow of the entire display process.

First, the output sizes HA and VA of the image displayed in order to arrange the additional word are set as the output size q shown at 303 in FIG. 4 and are called from the designated image file [1]. Next, information on the maximum displayable horizontal and vertical sizes HM and VM of the main display section 802 is sent to the CPU 201 [2 pieces]. CPU
201 calculates the display magnification SA based on the output image sizes HA and VA and the sizes HM and VM of the main display section [
3.

That is, if the magnification of image display is S^, then 5A-HA
/HM becomes.

If the result is VA XSA < VM [4], that is, the vertical image size VAXS^ and the main display area
2, and if the image does not actually fit within the displayable range at the display magnification SA, the display magnification is determined by matching the vertical sizes [5]. That is, 5A=VA/VM. In other words, the horizontal or vertical dimensions of the image to be displayed are changed to match the main display section 802, and the main display section 802 is
Display on 02 [6].

Also, if there is an additional word displayed along with the entire image, if the output size of the additional word is IA and the size displayed on the display screen is LA, then LA - IA XS
It becomes A. In other words, the additional words are displayed at the same magnification as the display image is enlarged or reduced [7]. As a result, both the image and the additional word can be confirmed on the main display section 802 in the same proportion as the final size to be output on the photosensitive material.

Next, the case of partial display mode will be explained based on FIG. 13.

The display magnification of the partial display is appropriately determined as a fixed value S8 in accordance with the resolution of the display unit 215 and human cognitive ability. Then, the CPU 201 is first commanded this fixed value S8 [1
]. Next, the vertical and horizontal sizes HaSVo on the cutlery of the image to be displayed are taken into the CPU 201 [2]. Display unit 215 by keyboard 213 and mouse 214
The part you want to display in the whole display mode displayed in HB
, input Vs [3 pieces. The CPU 201 calculates the size of the image from the magnification ratio S6, Ha, Ve, Ha, and Vo, and displays an arbitrary part on the main display section 802 at the display magnification Ss. If so, it is multiplied by the display magnification S8, which is the same as the image magnification, and displayed together with the image [
5]. Partial display performed in this way is used when determining the relationship between an additional word and an image, such as the exact position, size, and suitable font. It is possible to easily confirm which part of the whole image should be partially displayed.

Next, the method of processing when arranging the addition 5n in an image will be explained using FIG. 14. First, image data is read from the image file F2 and displayed on the main display section 802.

Predetermined additional classes are arranged using an arbitrary point in this display image as the origin. First, the first arrival point 1401, which is the origin,
Set. This is done by inputting an arbitrary position from an input device such as the keyboard 213 or mouse 214 shown in FIG. Next, another trailing point 1402 is set at an arbitrary position on the screen. Then, the group size area 1403 becomes the first arrival point 1401
A rectangle whose diagonal is a straight line connecting 1402 and the last arrival point 1402 appears on the screen with the center of the rectangle being the same. This set size area 1403 represents on the screen the area occupied by the set of additional classes that are currently being placed, and is calculated by multiplying the horizontal and vertical widths of the character strings that make up the additional class by the display magnification S of the display image. It is something. The horizontal width and vertical width are determined by multiplying the character size, line pitch, etc. in the set processing data specified at 304 in FIG. 4 by the number of characters.

When the first arrival point 1401 is fixed and the second arrival point 1402 is moved using a mouse or the like, the set size area 1403 also moves accordingly. This facilitates accurate translation and small movements of the set size area. When the arrangement of the set size area is completed in this way, a command is given from the input device to display a predetermined addition type in the set size area 1403.

The additional items whose placement has been completed are stored in the form of a character board together with the placement position information in the image in the second image file 305 in which additions 8n have been placed.

Next, the two-point placement algorithm according to the above 1401 and 1402 will be explained based on FIG. 15.

First, calculate the size of the set dimension area 1403 from the size of the addition class and set it as XS1''!l/S [1]. Specify the first point as the coordinate (Xr,'/1) [2]. Next, Decide on the landing point 45X (X2, V2) IM [3] So (7)
From the two points, find the center coordinates of the set dimension area from Xo - (Xl+X2)/2'jo = (V+ +Vz)/2 [4].

Center coordinates Xo, Yo and size of set dimension area Xs, Y
The origin (X1) when actually displaying the set dimension area from s
Y) is determined by the following calculation: X −X O−(x s / 2 ) Y=Vo (Vs/2) [5].

In this way, the display coordinates of the set size area are calculated and displayed on the main display section 802 together with the image. If you want to change the position of the set dimension area [6] Move the last landing point [7]
]. At this time, add the moved displacement to the previously determined arrangement point coordinates X and Y [81°, that is, x'-x+Δx/2 Y==Y+Δy/2 to find new coordinates [9]. This completes the placement,
Additional classes are displayed in this set size area [10].

[Effects of the Invention] As explained above, the present invention allows characters and images input separately to be handled independently, and also allows text data and additional word data to be sent to the output device 218 as codes. Since the corresponding characters are read out from the character font memory and output, it is possible to reproduce them without losing character quality. By handling text and images separately as described above, even if the printed matter is a complex mixture of text and images or a large amount of data, there is no need to worry about positioning for layout or magnification of the reproduced image. You can proceed with the input work independently without being interrupted.

Then, the output image size HA, VA and the display size HM of the main display section are set so that the compositing work can be performed on the screen of the display device.
, the relationship with the V bar, the designation of the set size area of the additional class, the designation of its placement position, etc. can be confirmed as they are actually output on the photosensitive material.
