ー画像が記録される。[Prior Art] Various types of display hard copy devices have been proposed, but when taking a hard copy of a color image, the RGB pixels stand out when taking a photograph of what is displayed on a color cathode ray tube, making it difficult to obtain a detailed photograph. cannot be taken. Therefore, a monochrome cathode ray tube is used, and each color of RGB is sequentially switched and displayed, and the image on the display screen is passed through an RGB filter in synchronization with the switching timing, and the output of the filter is photographed on color film. . In this way, RGB 3
A fine color image is recorded by exposing the same color film to light.
［発明が解決しようとする課題］
しかしながらこのような従来の装置において、
フイルムの色感光特性が均一でないので、撮影さ

いことがある。また、撮影された色はフイルムの
発色特性に拘束され、微妙な色調を再現するのは
困難であつた。[Problems to be solved by the invention] However, in such conventional devices,
Since the color sensitivity characteristics of film are not uniform, the colors photographed may not faithfully reproduce the colors of the actual subject. Furthermore, the colors photographed are limited by the coloring characteristics of the film, making it difficult to reproduce delicate tones.
［課題を解決するための手段］
このような課題を解決するためにこの発明は、
Ｒ，Ｇ，Ｂのそれぞれの色毎に独立に他の色を所

It is equipped with a mixer that independently mixes each of the R, G, and B colors with other colors at a predetermined ratio.
［作用］

Green and blue color signals are supplied, and these are supplied to matrix circuits 1 1 , 1 2 , and 1 3 . If the inside of the matrix circuit is shown with symbol 1 1 , attenuator 1 1 for each R, G, B signal.
It consists of a mixer 1 1d that mixes a , 1 1b , 1 1c and their attenuator outputs. Among these matrix circuits, for example, the red signal circuit is explained. This circuit corrects the red color by mixing some green and blue signals with the red signal. Therefore, the red signal attenuator 1 1a has almost no attenuation amount, and the other green and blue attenuators 1 1b and 1 1c have a large attenuation amount, and the attenuation amount is appropriately determined according to the amount of correction to achieve a desired color tone. Other matrix circuit 1 2 ,
The same goes for 13 , the green component is corrected with red and blue, and the blue component is corrected with green and red.

所望の色に微調整することができる。 The signals subjected to color correction in this manner are sequentially switched by the switch 2 and displayed on the cathode ray tube 3. Therefore, on the cathode ray tube 3, a red signal image, a green signal image, and a blue signal image are sequentially displayed. Therefore, the filter 4 is switched in synchronization with the switching timing of the switch 2 so that the filter is the same as the display color, and the camera 5
If the shutter is released while taking pictures, a color film (not shown) is exposed to each color of R, G, and B in sequence, and a color picture can be taken. and,
Each color of R, G, and B can be adjusted independently by adjusting the amount of attenuation of the attenuator in the matrix circuit, so even if the photosensitive characteristics of the film are not uniform depending on the color, the color will be the same as that of the subject. The color can be photographed as Further, it is possible to finely adjust the desired color according to the color development characteristics of the film.
