Patent ID: 8743273

Claim:
A solid-state imaging device comprising: an imaging area in which a plurality of unit cells are arranged in rows and columns; and a row scanning unit configured to perform pixel reset scan and pixel readout scan in the imaging area on a row-by-row basis, wherein each of the unit cells includes: two or more photodiodes each of which converts incident light into electric charges; a floating diffusion unit configured to hold the electric charges; a transfer transistor which is provided in correspondence with the two or more photodiodes and transfers the electric charges from the photodiodes to the floating diffusion unit; and a reset transistor which resets electric potential of the floating diffusion unit, wherein, in each of the unit cells, the two or more photodiodes share the reset transistor and the floating diffusion unit, the row scanning unit is configured to activate a mechanical curtain synchronous shutter mode in which pixel reset scan is performed and exposure of the imaging area is started by the pixel reset scan and is ended by light shielding by a mechanical curtain shutter, the pixel reset scan meaning that scan on a row-by-row basis is performed on pixel reset in which the photodiodes are reset by turning on the transfer transistor and a corresponding reset transistor, in the mechanical curtain synchronous shutter mode, the pixel reset scan is performed according to traveling characteristics of the mechanical curtain shutter, and the pixel reset scan includes performing a pixel reset operation simultaneously on the unit cells of different rows.
