A color image recording apparatus wherein a color photosensitive material is exposed by light responsive to a color still image signal. The apparatus comprising a device for obtaining picture element data by sampling color signals of three primary colors of the still image, a device for .gamma.-correcting the picture element data to be recorded, an FOT for exposing the color photosensitive material by three primary colors responsive to the picture element data from the device for .gamma.-correction, a horizontal deflecting device for horizontally sweeping the electron beam of the FOT; and vertical deflecting device for vertically sweeping the electron beam.

Color image recording apparatus

There is presented an optical screen suitable for taking a picture by placing it between the object and a photosensitive material. The optical screen has a specific means for controlling the difference in transmission density in an optically heterogeneous pattern and/or the specific area of the lower transmission density portions, typically an electrochromic display device. By use of such a single optical screen having a variable optically heterogeneous pattern, cumbersome operations for displacing one screen for another in the prior art can be obviated.

Photographic screen

In a photographic device, there are provided (a) a means for measuring luminous intensity distribution on an object and (b) a screen means for controlling gradation of an image to be formed on a photosensitive material in accordance with the luminous intensity distribution and/or maximum/minimum luminous intensity difference of the object measured by the means (a).
