Abstract
A solid-state imaging includes a comparing circuit, an inverting circuit, and a masking circuit, and performs column parallel AD conversion processing of analog pixel signals outputted from a plurality of pixels arranged in a two-dimensional matrix form. The comparing circuit outputs a difference signal obtained by comparing each of the pixel signals outputted from the pixels with a reference signal having a ramp waveform. The inverting circuit inverts a logic of the difference signal outputted from the comparing circuit. The masking circuit masks an output of an output signal of the inverting circuit to a circuit in a subsequent stage during an input offset canceling period in which the comparing circuit is canceling an input offset between the pixel signal and the reference signal.
