Abstract

PURPOSE:To prevent the ghost image, by a given operation processing based on the luminance information read in through the scanning of two color picture, one of which is balck, and the color picture information of another intermediate color, and by the pickup of the picture information of specific color. CONSTITUTION:The reflection light with line scanning of the original plane 1 with a slit lighting lamp 2 is fed to the 1st CCD5 via a lens 3 and half mirror 4 to read in the luminance information HY of the original plane 1. Further, the reflection light passing through the half mirror 4 is fed to the 2nd CCD7 via a red filter 6 to read in the red video information HR being the intermediate color of the original plane 1. Further, the luminance information HY and the red video information HR are through amplifiers 8, 10 and logarithmic amplifiers 9, 11, then operational processing as shown in equations (1) and (2) is made to pick up the video information R of the specific color.
