Abstract:
A signal processing device includes a control unit that suspends supplying of a signal to an A/D conversion unit which performs A/D conversion, during an A/D conversion period in which the A/D conversion is performed on the signal that depends on an electric charge read from a pixel; and a maintenance unit that maintains a signal value of the signal in a state where the signal is supplied by the control unit to the A/D conversion unit and that supplies the maintained signal value to the A/D conversion unit in a state where the supplying of the signal to the A/D conversion unit is suspended by the control unit.
