SOLID STATE IMAGING ELEMENT AND CAMERA SYSTEM

A solid-state imaging device and a camera system are provided that are capable of preventing the occurrence of invalid frames if a shutter and a gain are simultaneously set. The solid-state imaging device has a picture element array block 110 on which a plurality of picture element circuits having features for converting an optical signal into an electrical signal and accumulating the electrical signal in accordance with an exposure time are arranged in a matrix manner, a picture element drive block 120 drivable so as to execute a shutter operation of said picture element block and a read operation in accordance with setting data, and an interface section 170 including functions of holding shutter setting data and gain setting data supplied from the outside and controlling a timing for reflecting shutter setting and gain setting onto at least said picture element drive block. The interface section 170 includes a function of reflecting a gain on a frame next to one frame after setting.
