The pieces are cut piece by piece and discharged onto a tray 56.

FIG. 3 shows the electrical configuration of the present invention.

A TV left camera 8 and a video image input device 60 built into the photo printing apparatus main body 2 are connected to a selector 6I.

This video image human power device 60 is for inputting video signals such as graphics stored in an image storage medium.

The selector 61 connects the TV left camera 8 and the video image input device 6.
Select one of the video signals input at 0 and send it to A/
The signal is sent to a D converter 62, where it is converted into a digital signal.

The video signal converted into a digital signal is separated into color signals and stored in the memory 63 via the image processing device 29. The memory 63 can also store a plurality of video images so that a plurality of negative images can be printed side by side.

The image processing device 29 performs image synthesis, for example, arranging different images or the same image in a matrix, or inserting characters and figures into a video image, as well as enlarging, reducing, shifting, color and color of images. Perform density correction. This image-processed video signal is converted into an analog signal by a D/A converter 72, and then sent to a monitor system and a print system, respectively. This monitor system is composed of a driver 73 and a monitor 40, on which a video image to be printed is displayed in color. The printing system is
It is composed of a positive/negative inversion circuit 66, a selector 67 for taking out inverted three-color signals (red signal, green signal, blue signal) at the time of selection, a driver 68, and a CRT 27.

The keyboard 65 includes a power key, a print start key, etc., and is used to input necessary commands to the controller 64.

The controller 64 controls the filter adjusting section 18 . Shutter drive section 25. Filter switching section 4
5, etc., and processing tanks 50 to 5.
2. Drying drum53. A photographic developing section 70 consisting of a cutter 54 and the like, a mirror driving section 71. Selector 61, 6
7 etc. will be sequence controlled.

Next, the operation of the above embodiment will be explained. When printing a negative image, a color negative film 14 to be printed is set on the film deck 13. Usually, the color filters 15 to 17 are inserted at standard positions, and the illumination light emitted from the white light source 11 in a dimmed state is adjusted to have standard light quality. The filter adjustment section 18 is
The amount of insertion of the color filters 15 to 17 into the optical path 23 is automatically adjusted according to the measured value measured by a scanner (not shown). After this adjustment, if you operate the print key on the keyboard 65, the white light source 1 will emit full light, and
Since the shutter 24 is opened for a predetermined period of time, the negative image on the color negative film 14 is printed onto the photographic paper 4 by the printing lens 20. When printing of this negative image is completed, the color filters 15 to 17 are returned to their standard positions, and the white light source 11 is brought into a dimmed state. At the same time, the unexposed photographic paper 4 is pulled out from the magazine 3, and the exposed portion is sent to the developing processing chamber 48.

The above procedure is repeated to print a plurality of negative images on the photographic paper 4, but this portion is temporarily stocked as a loop. When a predetermined number of frames have been exposed, the cutter 9 is operated to cut the paper into short pieces and transport the exposed photographic paper 4 toward the color developing tank 50. This short length of photographic paper is transferred to a color developing tank 50 by a roller 55. Bleach-fix tank 51. Washing tank 52. Photographic development processing is performed after successively passing through a drying drum 53. The color photographic paper on which a positive image has been formed through development processing is cut frame by frame by a cutter 54 and then discharged onto a tray 56.

Next, referring to FIG. 4, a case will be described in which a plurality of negative images are printed into one printed photograph using a CRT exposure system. First, the color negative film 14 is set on the film deck 13, and the printing lens 20 is removed from the opening 21.

Next, when the keyboard 65 is used to instruct the switching of the CRTR optical system, the TV left camera 8 is turned on and the white light #1 is turned on.
1 emits light to illuminate a color negative film 14 set on a film deck 13.

Further, the double-sided mirror 22 in the retracted position is rotated by the mirror drive unit 71 and inserted into the optical path 23 with an inclination of 45 degrees. At the same time, the filter adjustment unit 18 adjusts the quality of the illumination light.

The light that has passed through the color negative film 14 is passed through the double-sided mirror 2
2 and enters the TV camera 28 where it is converted into a video signal. This video signal is sent to the selector 61. A/
sent to the image processing device 29 via the D converter 62,
It is stored in the memory 63. The color negative film 14 is moved and the next frame is imaged and stored in the memory 63.

After the frames are sequentially imaged in this manner, the keyboard 65 is operated to insert and synthesize each frame. After confirming this composite state on the monitor 40, the print key on the keyboard 65 is operated to print the composite video image. That is, since this synthesized video image is stored in the memory 63, the synthesized video image is read out from the memory 63 and sent to the selector 67 via the positive-negative inversion circuit 66. The selector 67 first takes out, for example, a red image signal, sends it to the CRT 27 via the driver 68, and causes the CRT 27 to display an image corresponding to the brightness of the red image (more precisely, a negative image of the red image). When a red image is displayed in black and white on this CRT 27, the red filter 42
The printing lens 41 is inserted into the optical path of the lens 41, and the black and white image displayed on the CRT 27 is converted into a red image. In this state, the shutter 24 is opened for an exposure time determined according to the red sensitivity of the photographic paper 4, and a red image is printed on the photographic paper 4 during this time.

After exposure of the red image, the shutter 24 is closed, during which the red filter 42 is retracted and replaced by the green filter 4.
3 is inserted. At the same time, the green image is displayed in black and white on the CRT 27. Immediately after this, the shutter 24 opens again, so that the black and white image displayed on the CRT 27 is converted into a green image by the green filter 43 and exposed onto the photographic paper 4.

Similarly, the blue image displayed on the CRT 27 is on the photographic paper 4.
exposed to light. When a video image is printed on the photographic paper 4 by this three-color plane sequential exposure method, the photographic paper 4 is moved by one frame, and the unexposed portion is set at the exposure position.

As mentioned above, the exposed photographic paper 4 is transferred to the developing processing chamber 4.
The images are sent within a day, subjected to photo development processing, cut frame by frame, and then discharged onto a tray 56.

As shown in FIG. 4, by the above-mentioned fitting composition, a print photograph 79 is created by printing the four negative images 75 to 78 on the color negative film 14.

5 and 6 show another embodiment of the invention, and the same members as in FIGS. 1 and 2 are given the same reference numerals. In this embodiment, two optical path switching mirrors 82.8
3 is placed in the printing optical path and rotated by a mirror drive section 84. One optical path switching mirror 82 is used to guide the video image of the CRT 27 to the photographic paper 4, and the other optical path switching mirror 83 is used for imaging the color negative film 14 by the TV camera 28.

When printing a color negative film, the two optical path switching mirrors 82 and 83 are retracted from the printing optical path as shown in FIG.
Burned into. When printing a video image, two optical path switching mirrors 82 and 83 are inserted into the printing optical path by a mirror drive device 84, as shown in FIG. A negative image is captured by the TV camera 28 via the optical path switching mirror 83, subjected to image processing, and then displayed on the CRT 27. The video image displayed on the CRT 27 is printed onto the photographic paper 4 in the three-color plane sequentially, as described above.

In the embodiment described above, four different negative images are printed on one printed photograph, but it is also possible to print a plurality of the same negative images side by side.

It is also possible to synthesize a single negative image with characters input using a keyboard or the like, or a computer graphics image created with a digitizer, display this synthesized image on a CRT, and print it on photographic paper.

In addition, when printing a video image as in the past, this video image is input from the video image input device 60, color and density correction is performed by the image processing device 29, and then the video image is printed on the CRT 27.
It should be displayed in .
