Abstract:
1. A solid-state image pickup device comprising: a pixel array part in which a plurality of pixels each including a photoelectric conversion element are arrayed in a one-dimensional direction or in two-dimensional directions; and signal processing parts for performing predetermined signal processing on pixel signals outputted from the pixels, each of the signal processing parts having an A/D converter for converting an analog signal into a digital signal, the A/D converter including at least a modulator, wherein the modulator is a ΔΣ modulator, and the A/D converter further includes a digital filter, further comprising an output control part for sequentially selecting and outputting digital image signals converted by a plurality of A/D converters, wherein the output control part includes latches and shift registers, and wherein a source voltage for the digital filter, the latches and the shift registers is made lower than a source voltage for the ΔΣ modulator and the pixel array part.
