System for producing colour image signals.

摘要

The present invention relates to a system for producing image signals for photographing an image of a subject by means of a solid state image sensing device or the like and for producing a brightness signal and line sequential color difference signals from the image signal. According to the present invention, the image of the subject is image-sensed by means of the image sensing device formed with a color filter wherein a first horizontal scanning line arranged therein with filter elements opposed to an image sensing plane, for separably transmitting at least red light and green light and a second horizontal scanning line arranged therein with filter elements opposed to the image sensing plane, for separable transmitting at least blue light and green light are alternately arranged, to thereby obtain image signals. The image signal thus obtained is signal-processed to produce the line sequential color difference signals R - Y and B - Y. With this signal-processing, the system can produce the image signals including the line sequential color difference signals with a simplified arrangement without imparring the color productivity.
