Title:
SOLID-STATE IMAGING ELEMENT, IMAGING DEVICE, AND SOLID-STATE IMAGING ELEMENT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/054184
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the number of wirings in a CDS processing circuit of a solid-state imaging element performing CDS processing. A data output unit alternately and repeatedly outputs predetermined reset data and signal data corresponding to an exposure amount. One pair of reset data holding units alternately hold the repeatedly output reset data. A pixel data generation unit repeatedly performs processing for generating pixel data corresponding to a difference between the reset data held in one of the one pair of reset data holding units and signal data output subsequent to the reset data. One pair of pixel data holding units alternately hold the repeatedly generated pixel data. An output-side selection unit alternately selects one of the one pair of pixel data holding units and outputs the pixel data held in the selected pixel data holding unit.
