PIXEL ARRAY FOR OPTIMIZING DUAL CONVERSION GAIN OPERATION OF PIXELS SHARING FLOATING DIFFUSION REGION AND IMAGE SENSOR INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240334088 titled 'PIXEL ARRAY FOR OPTIMIZING DUAL CONVERSION GAIN OPERATION OF PIXELS SHARING FLOATING DIFFUSION REGION AND IMAGE SENSOR INCLUDING THE SAME
The patent application describes a pixel array that includes unit pixel groups and two column lines for each column. Each unit pixel group consists of rows, with a first pixel group and a second pixel group arranged in a row direction. A pixel signal is output by simultaneously reading out unit pixel groups connected to a first column line and not sharing a first floating diffusion region, and unit pixel groups connected to a second column line without sharing a second floating diffusion region. At least one of the floating diffusion regions is positioned between a dual conversion transistor and a reset transistor.
- Unit pixel groups with two column lines
- First and second pixel groups arranged in a row direction
- Simultaneous reading out of pixel signal

Original Abstract Submitted
a pixel array includes: unit pixel groups; and two column lines provided for each column. each of the unit pixel groups includes rows, a first pixel group comprising a plurality of pixels, a second pixel group comprising a plurality of pixels. the first pixel group and the second pixel group are arranged in a row direction. a pixel signal is output by simultaneously reading out: unit pixel groups that are connected to a first column line and that do not share a first floating diffusion region, and unit pixel groups that are connected to a second column line different from the first column line and that do not share a second floating diffusion region. at least one of the first floating diffusion region and the second floating diffusion region is between a dual conversion transistor and a reset transistor.
