Document Type and Number:
WIPO Patent Application WO/2023/050029
Kind Code:
A1
Abstract:
An exposure control circuit, a related image sensor, and an electronic device. The exposure control circuit is configured to control the exposure of a pixel array. The exposure control circuit comprises: a first sub-exposure control circuit, a second sub-exposure control circuit, a third sub-exposure control circuit, and a fourth sub-exposure control circuit that are arranged in two rows and two columns and correspondingly coupled to a first pixel group, a second pixel group, a third pixel group, and a fourth pixel group of the pixel array. In a first exposure mode, the exposure control circuit controls a first part of pixels, a second part of pixels, a third part of pixels, and a fourth part of pixels of the first pixel group to have a first exposure time length. In a second exposure mode, the exposure control circuit controls the fourth part of pixels of the first pixel group, a third part of pixels of the second pixel group, a second part of pixels of the third pixel group, and a first part of pixels of the fourth pixel group to have a ninth exposure time length.
