Title:
SOLID-STATE IMAGING ELEMENT, IMAGING DEVICE, AND CONTROL METHOD FOR SOLID-STATE IMAGING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/012051
Kind Code:
A1
Abstract:
The purpose of the present invention is to lengthen an exposure time in an imaging device that composites a plurality of images.
A gain processing unit increases or decreases a plurality of image signals by gains different from each other, respectively. An analog-to-digital conversion unit generates a plurality of pieces of image data by analog-to-digital conversion of the increased or decreased plurality of image signals. A calculation unit adds data obtained by multiplying short-time exposure data that is any of the plurality of pieces of image data by a ratio between the gains and data not corresponding to the short-time exposure data among the plurality of pieces of image data, and outputs a result of addition as long-time exposure data. A composition unit composites the short-time exposure data and the long-time exposure data at a predetermined composition ratio.
