ABSTRACT:
An image signal processing device enables white balance with high precision to be obtained while causing circuit scale to be reduced, causing number of control line to be small, and causing influence of dispersion of elements to be small. The image signal processing device consists of a gain controller for adjusting a signal level into a prescribed signal level in every a plurality of color signals outputted from the color image sensor, an analog/digital converter for converting an image signal obtained from an output of the gain controller into a digital signal successively, and a controller for controlling a gain of the gain controller, wherein the controller inputs therein at least more than one control signal of a synchronizing signal which is switched in every respective pixels while synchronizing with an arrangement of a color filter of a color image sensor, a synchronizing signal which is switched in every respective lines, a synchronizing signal which is switched in every respective frames, a synchronizing signal which is switched in every respective fields, and a gain set value in every respective arrangement of the color filter.
