Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

〔Example〕

In FIG. 5, which shows an example of a photographic printing apparatus embodying the present invention, a photosensitive material such as color paper 2 is placed opposite a white light source 1. As shown in FIG. The color paper 2 is wound into a roll, pulled out by a pair of pull-out rollers 3, and set at an exposure position formed behind a mask 4. At this exposure position, after a predetermined number of frames have been exposed, the color paper 2 is cut into short pieces by a vine 6 and sent to a development processing section 8 by a feed roller 7.

In this development processing section 8, the color paper 2 is passed through each processing tank and subjected to photographic development processing, and finally, the color paper 2 is cut into one frame at a time by a cutter 9 and then discharged onto a tray 11.

A diffusion box 13 is provided above the white light source 1, and a cyan filter 1.14, a magenta filter 15. A yellow filter 16 is arranged.

White light emitted from a white light source 1 passes through a diffusion box 13 and illuminates an original picture, for example a color negative film 17, from below. This color negative film 17 is placed on a film deck 18.
, and is pressed down with a negative mask 19 from above. The filter adjustment unit 22 controls the insertion amount of each of the color filters 14 to 16 into the printing optical path 23 when the white light source l emits light, and controls the illumination according to the image on the color negative film 17 (hereinafter referred to as a negative image). Adjust the quality of light. By using reversal color paper and a special developer, it is also possible to print a positive image on reversal film.

A printing lens 24 is disposed in a printing optical path 23 between the color negative film 17 and the color paper 2, and a shutter 26 controlled by a shutter control section 25 is provided between the printing lens 24 and the color paper 2. It is being

During this movement, the first mirror 27 is inserted into the printing optical path 23 between the printing lens 24 and the color negative film 17 at an angle of 45 degrees. Incidentally, during photographic printing of a negative image, the movable table 29 retreats to a position where the first mirror 27 is retracted from the printing optical path 23. When the first mirror 24 is inserted into the printing optical path 23, the negative image is guided to the imaging optical path 31, and the negative image is captured by the TV camera 28. When the TV camera 28 captures an image, it outputs a red video signal R9 and a green video signal G.
, blue video signal B is output, and this is sent to the A/D.

The frame memory 33 is composed of three memory sections that store red, green, and blue video signals, respectively.
Write and read operations are performed according to instructions from the CPU 20. The three-color video signals written in the frame memory 33 are read out at an address specified by the CPU 20 after the writing is completed, and sent to the image processing section 35 via the pass line 34. Note that when reducing the size, the video signal is thinned out and read out from the frame memory 33.

This image processing section 35 performs image processing such as color correction and nine gradation correction. This image-processed signal is sent to the frame memory 36 via the pass line 34 and written to the address specified by the CPU 20. This frame memory 36
is for storing the signals of the composite image that has been inserted and composited, and like the frame memory 32, the signals of red, green,
It is composed of three memory sections each storing a blue image signal.

The image signals read from the frame memory 36 are sent to the monitor system and print system, respectively.

This monitor system includes a negative/positive inversion circuit 37. It is composed of a D/A converter 38 and a monitor 39 made of, for example, a color CRT, and displays the embedded composite image to be printed on this monitor 39 as a color positive image. The printing system includes a D/A converter 41 and a selector 42 for selectively taking out three-color video signals according to instructions from the CPU 20. Driver 43. It is composed of CRT44. Note that when capturing an image of a color reversal film, positive/negative reversal processing is performed in the image processing section 35.

The second mirror 45 is driven by a mirror drive unit 46 controlled by the CPU 20, and is connected to the printing optical path 23 between the printing lens 24 and the color paper 2 during printing of the index photographic image.
is inserted at a 45 degree angle. Note that when printing a negative image, the mirror drive unit 46 is rotated around the shaft 45a.
As a result, the light is evacuated from the printing optical path 23 as shown by the dotted line. The printing optical path 4 between this second mirror 45 and the CRT 44
A printing lens 48 is arranged at 7, and a red filter 50 for exposure is provided between this printing lens 48 and the CRT 44. Green filter 51. Three color filters, a blue filter 52, are arranged.

When printing a video image, the filter driving unit 53 inserts filters 50 to 52 of each color into the printing optical path 47 to perform additive color sequential exposure.

The keyboard 54 inputs necessary commands to the CPU 20. The CPU 20 executes the white light source 1. according to the program. Filter drive units 22 and 53. Drive section 30, frame memories 33 and 369, image processing section 35, selector 42. Sequence control is performed on the mirror drive unit 46 and the like.

FIGS. 7 and 8 show color paper 2 that has been exposed and photographically developed. Photos 60, 61,
63 and 64 are images printed by each frame of the color negative film 21, and index photographs 66 and 67 are images obtained by printing composite images electrically inserted and combined through the CRT 44. Here, symbols 60a and 61a
, 63a, and 64a show images in which the photographs 60, 61, 63, and 64 are reduced and inserted. Index photo 66.
The number of frames stored in 67 is set, for example, in a 4×4 matrix arrangement.

Next, the operation of the photographic printing apparatus having the above structure will be explained with reference to the flowchart shown in FIG. First, set the color negative film 17 to be printed on the film deck 18 and shoot the first frame.

Set it to the lint position. Usually, color filters 14 to 1
6 is inserted in the standard position, and the illumination light emitted from the white light source 1 which is in a dimmed state is adjusted to standard light quality. The filter adjustment unit 22 adjusts the color filters 14 to 1 according to the measured value measured by a scanner (not shown).
6 into the printing optical path 23 is automatically adjusted.

When the print key 54b of the keyboard 54 is operated, the white light source 1 emits full light and the shutter 26 is opened for a predetermined period of time, so that the image on the color negative film 17 is printed onto the color paper 2 by the printing lens 24.

When printing one frame of the photograph is completed, the CPU 20 turns the white light source 1 into a dimmed state and transports the color paper 2 by one frame. Further, the color filters 14 to 16 are returned to their standard positions, and the moving table 29 is moved to the left via the drive section 30.

As a result, as shown in FIG.
In order to move the V camera 28 in the horizontal direction, the first mirror 2
7 is inserted into the printing optical path 23 at 45 degrees.

When the color negative film 17 is illuminated with the white light emitted from the white light 'tA1, this negative image is reflected by the first mirror 27, guided to the imaging optical path 31, and sent to the TV camera 2.
8, where it is converted into a video signal. The three-color video signal output from the TV camera 28 is digitized by an A/D converter 32 and sent to a frame memory 33. The frame memory 33 writes three color video signals for one frame according to instructions from the CPU 20. For example, when the value of the number of embedded frames N is set to "16", the three-color video signal written to the frame memory 33 is divided into 1/16 according to the address specified by the CPU 20.
It is thinned out and read out.

Note that the value of N may be set in advance to a value m'' (m is an integer), such as r25J, r36, etc., in addition to "16".

The video signal read out from the frame memory 33 is sent to the image processing unit 35 via the pass line 34, where it is subjected to image processing such as color correction and 9-gradation correction. Then, it is sent to the frame memory 36 via the pass line 34, where it is written in the area designated by CPtJ20. C
The video signals sequentially read out from the frame memory 36 according to instructions from the PU 20 are transferred to a negative/positive inversion circuit 37. D/
Since the image is sent to the monitor 39 via the A converter 38, the combined image is displayed on the monitor 39. In this way, the image signals of the reduced negative image are written separately for each color in a predetermined area of the frame memory 36, thereby performing the inset composition, and this composite image is displayed on the monitor 39.

When writing to the frame memory 36 is completed, the CPU 2
0, the moving table 29 is slid to the right via the drive unit 30, and the first mirror 27 is retracted from the printing optical path 23. When printing the next frame, the color negative film 17 is moved by one frame and set at the print position. The above procedure is repeated, and each frame is sequentially printed on the color paper 2, and images of a plurality of frames are embedded.

When a predetermined number of frames are printed on the color paper 2, the cutter 6 is activated to cut the exposed portions into short pieces. This short color paper 2 is sent to a developing processing section 8 by a feeding roller 7, where it passes through each processing tank and undergoes photographic processing, and is then cut frame by frame by a cutter 9 before being discharged onto a tray 11. be done.

Next, when the embedding and compositing is performed up to the preset 16 frames, the CPU 20 starts photo printing of the index photo image that has been embedded and composited.

When printing this index photo image, the mirror drive unit 4
6, the second mirror 45 is inserted into the optical path 23 at an angle of 45 degrees. Further, the video signal of the composite image read from the frame memory 36 is sent to the printing system. This video signal is sent to the selector 42 via the D/A converter 41, which first takes out, for example, a red video signal, sends it to the CRT 44 via the driver 43, and outputs the red image (more precisely, the negative of the red image). A black and white image obtained by converting the video signal (image) into luminance is displayed on the CRT 44. While this CRT is emitting light, the filter drive section 53 inserts the red filter 50 into the printing optical path 47, so that the CRT4
The image No. 4 is converted to a red image.

This red image is transmitted to the second mirror 4 via the printing lens 48.
5, where it is reflected toward the color paper 2. In this state, the shutter 26 is opened for an exposure time that is determined according to the red sensitivity of the color paper 2, and during this time, a plurality of frames of red images repeatedly read out from the frame memory 36 are printed onto the color paper 2.

After exposure of the red image, the shutter 26 is closed, during which the red filter 50 is retracted and replaced by the green filter 5.
1 is inserted. At the same time, the green image is displayed in black and white on the CRT 44. Since the shutter 26 opens immediately after this, the black and white image displayed on the CRT 44 is converted into a green image by the green filter 51 and exposed onto the color paper 2.

A blue image is exposed onto color paper 2 in a similar manner.

When the index photographic image is printed on the color paper 2 by three-color sequential exposure as shown in FIG. It is evacuated from the optical path 23.

The flowchart in FIG. 2 and FIG. 6 show an embodiment in which the size reduction rate is changed depending on the designation of the number of frames to be inserted. In this embodiment, after setting the color negative film 17, the user operates the frame number designation key 54a provided on the keyboard 54 to designate the number of frames to be inserted into the composite image, for example, a matrix of 3X3, 4X4.5X5, etc. The CPU 20 sets a size reduction rate corresponding to this number of frames, thins out and reads out image signals from the frame memory 33 based on this size reduction rate, and, for example, if a 4×4 matrix is specified, 1
When printing of the sixth frame is completed, the index photo image is printed.

FIG. 3 shows an embodiment in which frames for one item are included in one index photo. In this example,
Taking into consideration the case where 37 frames are taken on a 36-frame film, for example, the setting is such that 42 frames (7 x 6 frames) are inserted and composited, and regardless of the number of frames inserted, one image will be generated. When the end of the order (the end of the same order) is confirmed, the composite image is taken out and printed. This one break can be determined by attaching a sensor to the film deck 18 and detecting the end of the color negative film 17. Further, when a plurality of color negative films 17 are joined together with a tape to form a long roll, this tape may be detected by a sensor.

Figure 4 shows a combination of the embodiments shown in Figures 2 and 3. After specifying the number of frames to be inserted, printing and embedding are repeated, and when N frames are embedded and composited. The composite image is taken out and printed when the composite image is inserted and composited every time and after that, up to one cut of N frames or less. FIG. 8 shows printed photographs created using this method, and index photographs 67 each having 13 frames are created. Also, set the number of embedded frames to “
16'' and when printing a 24-frame color negative film 17, a 16-frame index photo and an 8-frame index photo (the remaining frames are white) will be created.

In the above embodiment, the white light source 1 is used to print a negative image and a composite image. The present invention can also be applied to. When this CRT is used, it is also possible to print video images input from the image input section by removing the film deck, photographic film, and the like. Further, a combination of a color separation filter and a monochrome TV camera may be used to sequentially capture three-color planes. Furthermore, a film feeding means may be provided beside the film deck 18, and the color negative film 17 may be automatically fed by the film feeding means when printing of the negative image is completed.

〔Effect of the invention〕

As described above in detail, the index photo printing method of the present invention involves taking an image of a photographic film, writing it to the first memory, reading from this first memory, processing the two images, and writing it to the second memory. Repeat the operation, and when up to N frames have been inserted and composited, or when one break is confirmed, or every time N frames have been inserted and composited, and after that, the insertion is performed until the break for one frame below N frames is completed. When the comprehensive compositing is completed, the composite image is retrieved from the second memory and hard-copied, making it possible to easily create an index photo. Furthermore, since the image is read while the photographic film is being printed, index photographs can be created efficiently.
