Compensation Method for Sensitivity Difference between Two Exposure Areas of 133-Megapixel CMOS Image Sensor Fabricated with 1D-Stitching

Abstract

The 133-Megapixel CMOS image sensor, which is fabricated with 1D-stitching, has sensitivity difference between each exposure area. We have found that the boundary area has sensitivity difference with other exposure area. We have tested correcting sensitivity difference using different correction functions for each exposure area, and have confirmed obscuring the stitched boundary.
