Abstract

According to one embodiment, a solid-state imaging device includes a pixel array and a high dynamic range (HDR) synthesizing circuit. A pixel is configured as a small pixel group. The HDR synthesizing circuitincludes a valid pixel selecting unit, a sensitivity ratio correcting unit, and a calculation processing unit. The valid pixel selecting unitselects one or more small pixels validating a use of a signal value in the HDR synthesis as a valid pixel from among the small pixel group. The sensitivity ratio correcting unitexecutes sensitivity ratio correction on the signal value of each small pixel. The calculation processing unituses the signal value of the valid pixel among the signal values of the small pixels from the sensitivity ratio correcting unitfor a calculation for the HDR synthesis.
