CMOS image sensor with on-chip digital signal processing

摘要

A CMOS image sensor includes digital signal processing on-chip within the CMOS image sensor before being transmitted to an ISP (image signal processor) within an image sensor system. An on-chip digital processing unit is formed on a same one integrated circuit die with a pixel array and performs the steps of: performing a first set of at least one correction operation on the original digital signal to generate a corrected digital signal; formatting the corrected digital signal for the standard interface to generate a processed digital signal; and sending the processed digital signal to the ISP (image signal processor) via the standard interface.
