Patent ID: 8723099

Claim:
A solid-state imaging apparatus comprising: a plurality of unit pixels arranged in a matrix and configured to generate a signal by photoelectric conversion; a plurality of pixel output lines connected to each column of the plurality of unit pixels; a plurality of column amplifiers configured to amplify a signal of the plurality of pixel output lines; and a driving circuit configured to generate a control signal of the plurality of column amplifiers, wherein each of the plurality of column amplifiers comprises a first input terminal, a second input terminal, an output terminal, an input capacitance connected between the first input terminal and the second input terminal, and a first switch connected between the second input terminal and the output terminal, and wherein the driving circuit is configured to generate the control signal so as to make a period for switching the first switch from a conductive state to a non-conductive state longer than a period for switching the first switch from the non-conductive state to the conductive state.
