Title:
固体撮像装置
Document Type and Number:
Japanese Patent JP5855035
Kind Code:
B2
Abstract:
According to one embodiment, a solid-state imaging device includes a pixel array and a high dynamic range (HDR) synthesizing circuit 19. A pixel is configured as a small pixel group. The HDR synthesizing circuit 19 includes a valid pixel selecting unit 34, a sensitivity ratio correcting unit 35, and a calculation processing unit 36. The valid pixel selecting unit 34 selects 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 unit 35 executes sensitivity ratio correction on the signal value of each small pixel. The calculation processing unit 36 uses the signal value of the valid pixel among the signal values of the small pixels from the sensitivity ratio correcting unit 35 for a calculation for the HDR synthesis.
