Image sensor, electronic apparatus, and driving method of electronic apparatus

摘要

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).

主权项

1. An image sensor, comprising:
a pixel array section with two or more rows, each which includes a plurality of pixels; a control section configured to generate a control signal to effect reading of pixel signals from the pixel array section; and a driving section configured to control the pixel array section based on the control signal, wherein,
the driving section is configured to effect a reading of the pixels signals of at least a first row and a reset of the pixels of at least a second row simultaneously, andthe driving section controls the pixel array section to effect an electronic shutter occurrence where an electronic shutter occurrence number establishes intermediate rows between an address of a row currently being read and an address of a next row to be read, as determined by an address addition amount, which intermediate rows are subject to one or more electronic shutter operations for an anti-blooming purpose, pre-shutter purpose or both, but not for an integration period.
