In A, the desired size and number of photographs are entered using the ten keys 57. Further, a display unit 61 is included for confirming the data input using the ten keys 57, and the contents of the key operation are displayed on the display unit 61.

FIG. 4 is a flow chart showing a processing procedure when the electrophotographic system shown in FIG. 1 is used as a camera to obtain a photograph of a desired size and number of sheets.

The operator console 60 is operated to specify the desired size and number of photographs (steps 71 and 72). For example, if you need four resume photographs and three passport photographs as shown in Fig. 2, the console 60 shown in Fig. 1 shows "Enter key 58, driver's license size designation key 51, number of sheets". Key 5
6, the numeric keypad 57 for number 4, the passport size designation key 55, the number key 56, the numeric keypad 57 for number 3, and the end key 59 "are pressed in this order. In the case of the console 60A shown in FIG. 3, the desired size of the photograph is the numeric keypad.
Entered using 57. Specifically, "Enter key 58, size key 62, numeric keypad numeric keypad 57, multiplication key 57A,
Number 3 numeric keypad 57, number key 56, number 4 numeric keypad
Key 57, size key 62, number 5 numeric keypad 57, multiplication key 57A, number 5 numeric keypad 57, number key 56, number 3
The respective keys are pressed in the order of the ten key 57 and the end key 59 "of.

When the end key 59 is pressed, it is determined that the operation on the console 60 is completed (YES in step 73). Console
When the operation of 60 is completed, the resolution of the printer 41 connected to the data processing device 20 is read by the CPU 21 via the printer driver 25 (step 74).

Subsequently, the number of vertical and horizontal pixels required to obtain a photograph of a desired size input on the console 60 is calculated based on the resolution of the CCD 13 and the printer 41 (step 75). FIG. 5 shows a case where a desired photograph is obtained by using the printer 41 having a resolution of 300 dpi,
The relationship between the size of the picture and the number of pixels required to obtain the picture is shown. Fig. 5 shows a C with 1280 pixels vertically and 960 pixels horizontally.
Also shown is the decimation factor to obtain the number of pixels needed to obtain the desired size photograph when using a CD. As shown in FIG. 5, from the resolution of the printer 41 and the size of the photograph,
The number of pixels required to obtain the picture is calculated.

When the number of pixels required to obtain a desired photograph is calculated, the layout is determined based on the print paper set in the printer 41 and the size and number of desired photographs set by the console 60. (Step
76). Details of this layout determination processing will be described later.

When the layout is determined, the lens drive motor
The electric lens 11 is controlled under the drive of 12, the photographing range of the subject is set (step 77), and the subject is photographed (step 78).

Image data representing a subject by photographing is C
It is obtained from the CD 13 and is temporarily stored in the original image storage area 31 of the memory 30 included in the data processing device 20 via the signal processing circuit 14 and the analog / digital conversion circuit 15. The image data once stored in the original image storage area 31 is read out and stored in the CPU.
The thinning-out processing unit 23 performs thinning-out processing so that a photograph of a desired size can be obtained (step 79).

The thinning rate is determined as shown in FIG. 5 based on the desired photograph size input on the console 60 and the number of pixels of the CCD 13, and is stored in the original image storage area 31 at the determined thinning rate. The thinned-out image data is thinned out. The thinning rate is represented by how many pixels of the continuous pixels are thinned. For example, a thinning rate of 2/7 means thinning out two pixels out of seven pixels, and a thinning rate of 3/8 means thinning out three pixels out of eight pixels. If the thinning rate is 0, thinning is not performed.

The image data subjected to the thinning process is given to the output image storage area 32 and temporarily stored therein.

Until the image data representing the photographs of the size and number set by the console 60 are obtained, the CPU
The thinning-out processing is repeated for the image data stored in the original image storage area 31 in the thinning-out processing unit 23, and the image data representing the desired photograph is sequentially output.
Memorized in. The thinned-out image data is stored in the output image storage area 32 so that the layout decided in the layout decision processing is obtained (step 80).

The image data stored in the output image storage area 32 is read out and given to the monitor display device 42 as print data via the digital / analog conversion circuit 26, and the photograph to be printed is displayed. After this output image storage area
The image data stored in 32 is given as print data to the printer 41 via the printer driver 25, and a photograph of a desired size and number of images is obtained (step 81).

6 and 7 show step 76 in FIG.
5 is a flowchart showing the procedure of the layout determination process of FIG. Further, FIG. 8 shows an example of print paper loaded in the printer 41, and FIGS. 9A, 9B and 9C show examples of desired photograph sizes.

In this embodiment, the layout is determined so as to fill the print paper from the upper left to the right and in the order of the smaller vertical size of the desired photo size set by the console 60. . 9 (A), (B) and
(C) Three different size photographs, N ₁ and N, respectively
Consider the case of printing ₂ sheets and N ₃ sheets.

First, image numbers D _n are assigned to the input photographs in the order of increasing vertical size (step 91 in FIG. 6). For example, in FIGS. 9 (A), (B) and (C), the photograph shown in FIG. 9 (A) has a horizontal X ₁ and the vertical has Y ₁ , and the photograph shown in FIG. 9 (B) has a horizontal X ₂ and a vertical In the photograph of Y ₂ and FIG. 9 (C), the horizontal dimension is X ₃ and the vertical dimension is Y ₃ . Where Y ₃ ＞
Y _2> and Y _1. Therefore, as shown in Fig. 9 (A), (B) and
In (C), D ₁ , D ₂ and D ₃ are given as image numbers in the ascending order of vertical size.

Subsequently, the coordinates (X, Y) that determine the location of the photograph and the variable n representing the desired number of photographs are initialized (step 92). The origin of the upper left corner of the desired photograph is made to coincide with the coordinate (X, Y), whereby the location of the photograph is determined by the coordinate (X, Y). Further, the number N is set so that the number of desired photographs is counted from the smallest image number (step 93).

When the initialization is completed, the origin of the upper left corner of the photograph having the smallest image number D _n , that is, the smallest vertical size, coincides with the origin (0, 0) of the print paper shown in FIG. The arrangement of the photo on the print paper is determined so that the left side of the photo matches the left side of the print paper, and the upper side of the photo matches the upper side of the print paper (step 94). ). This arrangement is shown by hatching in FIG. Next, as shown in FIG. 8, when the photograph of image number D ₁ is arranged on the right side of the arrangement determined in step 94, the coordinates (x, y) of the upper right corner
Is calculated (step 95).

The calculated coordinates are the coordinates of the printer paper (X
o, Yo) is determined (step 9)
6).

When the calculated coordinates are within the coordinates of the printer paper (YES in step 96), the arrangement of the photograph of the image number D ₁ is sequentially determined in the right direction. In the example shown in FIG. 8, the photograph of the image number D ₁ can fit up to 5 sheets in the lateral direction of the print paper. The coordinates X are updated as the photographs are stored on the print paper (step 97), and the desired number N is also decremented by one (step 102 in FIG. 7).

If the calculated coordinates do not fall within the coordinates of the printer paper (NO in step 96), the coordinate X is initialized and the Y coordinate is updated (step 98). This update is performed by adding the coordinate Y _n representing the vertical size of the photograph placed before the update to the coordinate Y before the update. As shown in FIG. 8, the sixth photo out of the photos with the image number D ₁ does not fit in the print paper 43 horizontally. Therefore, if the coordinate Y is updated, the updated coordinate Y is Y = 0 + Y ₁ = Y ₁ . It is determined whether the updated coordinate Y falls within the coordinate of the print paper (step 99).

When the updated coordinate Y falls within the coordinate of the print paper (YES in step 99), the arrangement of the photographs is again determined in order to the right (step 102).

When the minimum image number D ₁ is arranged by the desired number N ₁ (YES in step 103, the next image number D ₂ is arranged (steps 104, 105, 94-10).
2). When the arrangement of the N ₂ pictures of the next image number D _{2 is completed} , the arrangement of the N ₃ pictures of the next image number D ₃ is further performed.

In the middle of the arrangement, the print paper 43 such as the second photograph of the image number D ₃ in FIG.
When the print paper 43 is pushed out and does not fit on the print paper 43 (NO in step 99), a page break is performed (step 100), and the coordinates are initialized again (step 101). When the page break is performed, the process from step 94 is performed again to determine the layout.

FIG. 10 shows the relationship between the resolution of the printer and the output size when a CCD having 640 pixels in the vertical direction and 480 pixels in the horizontal direction is used. If the resolution of the printer is different, the size of the photograph obtained from the printer is different even if the CCD has the same number of pixels. Therefore, by selecting a printer having a desired resolution, a photograph having a desired size can be obtained. Of course, a photograph having a desired size may be obtained only by selecting a printer having a desired resolution, but a photograph of a desired size may be obtained by combining with a thinning process.

FIG. 11 is a flow chart showing a processing procedure for obtaining photographs of a desired size and number of sheets when the electrophotographic generation system shown in FIG. 1 is used as a scanner. 11, the same processes as those shown in FIG. 4 are designated by the same reference numerals, and the description thereof will be omitted.

When the electrophotographic generating system shown in FIG. 1 is used as a scanner, a subject is scanned within the determined photographing range (step 78A), and image data representing the subject is stored in the original image storage area 31 of the memory 30. It The image data stored in the original image storage area 31 is read out, and an image cutting process is performed so that the image has a designated size (step 82). In this image clipping processing, the image data stored in the original image storage area 31 is given to the monitor display device 42 via the digital / analog conversion circuit 26, and the mouse is displayed while observing the subject image displayed on the monitor display device 42. This can be done by the operator specifying the cutout range using, for example. Further, if the subject is always present at the center position of the shooting range, it may be automatically cut out to a size designated with the center of the shooting range as a reference.

The image data representing the image cut out to the designated size in this way is output from the memory 30 so as to have the layout determined by the layout determining process (step 76) under the control of the CPU 21. The images are sequentially stored in the image storage area 32 (step 80).

Until the image data representing the desired size and number of photographs designated by the operator console 60 are obtained, the photographing range determination processing in step 77 and step 78A.
The subject scanning process is repeated and sequentially stored in the output image storage area 32 of the memory 30 (step 83). Image data representing the desired size and number of photographs is output image area
When it is stored in 32 (YES in step 83), it is given to the printer 41 as print data and printed by the printer 41. As a result, the desired size and number of photographs can be obtained.

In the printing process in the printer 41, the thinning-out process will be substantially performed according to the resolution of the printer 41.
