Document Type and Number:
WIPO Patent Application WO/2022/262443
Kind Code:
A1
Abstract:
An image sensor. The image sensor comprises: a pixel array (11), the pixel array (11) comprising a plurality of pixels (110), and each pixel (110) comprising a plurality of sub-pixels, wherein the sub-pixels in a same pixel (110) share a same floating diffusion region (FD); each pixel (110) comprising a pixel circuit (111) provided with a plurality of output ends, and the pixel circuit (111) being used for transferring charges generated by at least one photoelectric conversion element (1111) in a same pixel (110) to the floating diffusion region (FD) for accumulation, and selecting at least one output end of the pixel circuit (111) according to the accumulated charges to output analog signals corresponding to the charges in the floating diffusion region (FD); and a plurality of first conversion circuits (141), each first conversion circuits (141) being used for performing analog-to-digital conversion on each analog signal outputted by a same pixel circuit (111), and reading a converted digital signal together with the pixel circuit (111) on the basis of a full-resolution output mode or a first-stage combined output mode.
