Title:
IMAGE SENSOR AND DATA TRANMISSION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/113407
Kind Code:
A1
Abstract:
The present invention provides an image sensor comprising a pixel array module composed of pixel groups, multiple switch control modules, a PFA, a pipelined ADC and a decode module. Each pixel group comprises multiple unit pixels which form at least one unit pixel. Each switch control module corresponds to a row of the pixel array module and includes a first transmission circuit and a second transmission circuit. The PGA process the data outputted by the first and second transmission circuits and the pipelined ADC performs A/D conversion to the data outputted by the PGA. The decode module controls the first and second transmission circuits of each row to alternately read and transmit the unit pixel data, and controls all the first and second transmission circuits to successively output the data of the unit pixels readout thereby to the PGA.
