Patent ID: 8274588

Claim:
A solid-state imaging device comprising: a pixel array unit including pixels detecting physical quantities, the pixels in the pixel array unit two-dimensionally arranged in a matrix; and a driving portion reading a first signal corresponding to said physical quantities, which have been accumulated in a first accumulation time, of pixels of a first pixel group among the pixels included in the pixel array unit, the driving portion further reading a second signal corresponding to said physical quantities, which have been accumulated in a second accumulation time which is shorter than the first accumulation time, of pixels of a second pixel group which are adjacent to the pixels of the first pixel group, wherein, said reading of the physical quantities of the pixels in the second pixel group occurs in a beginning of the first accumulation time, said first and second signals read in a same frame; and a number of pixels in at least one of the first pixel group and the second pixel group is greater than a number of pixels in a pixel row.
