IMAGE SENSOR, ELECTRONIC APPARATUS, AND DRIVING METHOD OF ELECTRONIC APPARATUS
First Claim
1. 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; and
control means for determining an electronic shutter occurrence number within one horizontal scanning period, which is the number of rows where electronic shutters are simultaneously performed in one horizontal scanning period, by an operation based on an address addition amount (P1, P2, P3, . . . , PN) 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 amount (P1, P2, P3, . . . , PN).

Abstract
An image sensor that has a pixel array section in which pixels are arrayed in a two-dimensional manner in vertical and horizontal directions and that controls an exposure time of each pixel in a rolling shutter method is disclosed. The sensor includes control means for determining an electronic shutter occurrence number within one horizontal scanning period, which is the number of rows where electronic shutters are simultaneously performed in one horizontal scanning period, by an operation based on an address addition amount (P1, P2, P3, . . . , PN) when a vertical address movement amount of the pixel array section for every one horizontal scanning period in an exposure regulation shutter, which is an electronic shutter for regulating exposure, executed corresponding to electric charge reading in each pixel is expressed as repetition of the address addition amount (P1, P2, P3, . . . , PN).
