Patent ID: 8711260

Claim:
An image sensor, comprising: a pixel array section in which pixels are arrayed in a two-dimensional manner in vertical and horizontal directions, the pixel array section being controlled such that an exposure time of each pixel is controlled in accordance with a rolling shutter method; a circuit that generates address addition amounts (P 1 , P 2 , P 3 , . . . , P N ) of at least 1 each; and control means receiving the address addition amounts and calculating an electronic shutter occurrence number within one horizontal scanning period, which is the minimum number of rows where electronic shutters are simultaneously performed in one horizontal scanning period, by an operation based on each address addition amount (P 1 , P 2 , P 3 , . . . , P N ) when a vertical address movement amount of the pixel array section for every one horizontal scanning period in an electronic shutter for regulating exposure, executed corresponding to electric charge reading in each pixel, is expressed as repetition of the address addition amounts (P 1 ,P 2 , P 3 , . . . , P N ), wherein, the electronic shutter occurrence number establishes rows between the current address and the next row to be read, as determined by the relevant address addition amount, that are subject to one or more electronic shutter operations for anti-blooming purposes, pre-shutter purposes, or both purposes, but not for an integration period.
