ABSTRACT:
A solid-state image sensor includes a pixel section that outputs a signal charge subjected to photoelectric conversion by each of a plurality of photoelectric transducers, a conversion circuit that converts an output signal from the pixel section into a digital signal by using a triangular wave, and a saturation signal level calculation circuit that calculates a saturation signal level of each photoelectric transducer based on the digital signal from the conversion circuit. The solid-state image sensor further includes a setting circuit which sets a maximum signal level of the triangular wave in accordance with the saturation signal level from the saturation signal level calculation circuit.
