Abstract:
1. An image signal processing device using a color image sensor outputting a plurality of color signals, said image signal processing device comprising: a gain control means for adjusting a signal level into a prescribed signal level in every color signal of every pixel of said plurality of color signals outputted from said color image sensor; an analog/digital conversion means for converting an image signal obtained from an output of said gain control means into a sequence of digital signals; and a control means for controlling a gain of said gain control means for each color signal of each pixel of each line of each frame of an image, wherein said control means receives inputs therein corresponding to more than one control signal for each synchronizing signal which is switched in every respective pixel such that said control means provides gain control signals to said gain control means synchronized with an arrangement of a color filter of a color image sensor, a synchronizing signal which is switched in accordance with every respective line, a synchronizing signal which is switched in accordance with every respective frame, and a gain set value in every respective arrangement of the color filter.
