Patent ID: 8743251

Claim:
A solid-state image pickup device comprising: a pixel section with a plurality of pixel circuits in a matrix and configured for converting an optical signal to an electrical signal and for accumulating the electrical signal depending on an exposure time; and a pixel driving section capable of driving the pixel section through a control line so as to reset, accumulate, transfer, and output signal electric charge of the pixel section, wherein, the pixel section has a pixel shared structure in which each pixel circuit has a readout pixel and an unread pixel share an output node in common, which has one selection control line, one reset control line, and a plurality of transfer control lines, and which includes a readout pixel section and an unread pixel section in its entirety, and the pixel driving section includes a pixel control section configured such that, for each pixel section, the unread pixel is normally fixed in a reset state, and, when reading the readout pixel in a shared relationship, if its address is selected or a selection signal becomes active, the reset state of the unread pixel is cancelled to place the unread pixel into an unread state.
