Title:
IMAGE SENSOR, RELATED CHIP, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/012071
Kind Code:
A1
Abstract:
Disclosed are an image sensor (10), a related chip, and an electronic apparatus (20). The image sensor comprises: a pixel (12) for sensing light and generating an analog sensing signal; a gain amplifier (14) coupled to the pixel and used for adjusting a gain value according to the intensity of the light, and for amplifying, on the basis of the gain value, the analog sensing signal to generate a gained analog sensing signal; and an analog-to-digital converter (16) coupled to the gain amplifier and used for sampling the gained analog sensing signal by using a relevant multi-sampling technique, and for converting the gained analog sensing signal into a digital sensing signal, wherein the number of sampling times varies in real time according to the analog sensing signal.
