Patent ID: 8427566

Claim:
A pixel drive circuit, comprising: a plurality of pixel circuits each including a photoelectric converting unit for converting an incident light into an electric charge and accumulating the converted electric charge, the plurality of pixel circuits being arranged in a matrix; an address decoder that selects the pixel circuits to be controlled which are arranged on an identical line; a storage circuit that stores operation information to be executed by the pixel circuits selected by the address decoder; and a control circuit that controls an operation of the pixel circuits selected by the address decoder in accordance with a storage state of the storage circuit, wherein, a row selection control signal is received by the control circuit, the control circuit controls a charge discharging operation of discharging an electric charge remaining in the photoelectric converting unit of each of the pixel circuits, the storage circuit holds the storage state until the charge discharging operation is completed, the storage circuit includes a first storage circuit for storing information of the charge discharging operation, and the control circuit includes a logic circuit for causing the control circuit to execute the charge discharging operation irrespective of the storage state of the first storage circuit.
