Semiconductor image pickup device

摘要

The semiconductor image pickup device comprises a pixel array (1) having a plurality of pixels arranged in a matrix form. Each pixel comprises a photodiode (3mn) that converts an optical signal into an electric signal, and a transistor (4mn) connected to a charge accumulation section of the photodiode (3mn). A buffer (9n) is additionally provided. This buffer (9n) controls the transistor (4mn) of the pixels using a lower control power supply voltage than a power supply voltage of the pixel array (1). <IMAGE>
