Title:
IMAGE SENSOR AND SENSING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/082289
Kind Code:
A1
Abstract:
Disclosed are an image sensor and a sensing method therefor. The image sensor comprises a plurality of super pixels and a signal reading circuit, wherein the super pixel comprises a plurality of pixels, each of the pixels comprising: a light sensing assembly and sub-driving units. A main driving unit is connected to the sub-driving units to read an average sensing signal of the light sensing assembly in each pixel so as to obtain an average sensing signal closer to reality; and each super pixel is also connected to the signal reading circuit merely via a single transmission line so as to read the average sensing signal, thereby reducing the number of transmission lines and the layout area of the transmission lines.
