Patent ID: 8085324

Claim:
A solid-state imaging apparatus comprising: a plurality of pixels arranged in a matrix wherein each of the pixels converts incident light into an analog electric signal and outputs the analog signal; a plurality of A/D converters, each arranged correspondingly to one of columns of the pixels, and for converting the analog electric signal from one of the pixels into a digital signal to output the digital signal from an output terminal of the A/D converter; a plurality of register circuits, each arranged correspondingly to one of the columns of the pixels, for receiving by an input terminal thereof the digital signal outputted from the output terminal of one of the A/D converters, and for holding the digital signal; a connecting unit for selectively connecting the output terminal of the A/D converter arranged correspondingly to one column to the input terminal of the register circuit arranged correspondingly to another column, and connecting an output terminal of the register circuit arranged correspondingly to one column to the input terminal of the register circuit arranged correspondingly to another column; and an arithmetic operation unit for subjecting to a differential processing the digital signal outputted from each of the output terminals of the plurality of register circuits.
