ABSTRACT:
A system is provided for producing image signals of a photographed subject image by a solid state image sensing device and for producing a brightness signal and line sequential color difference signals from the image signal. The subject image is sensed by the image sensing device which has a color filter formed thereon. First and second horizontal scanning lines of picture elements are alternately arranged and the picture elements are opposed to filter elements of the color filter. The first horizontal scanning lines separately transmit at least red light and green light and the second horizontal scanning lines transmit at least blue light and green light, to thereby obtain color image signals. The image signal thus obtained are 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 by a simplified arrangement without impairing the color productivity.
