Black Level Correction in Image Sensors: What It Is and Why It Matters

Prabu Kumar
by Prabu Kumar
Black Level Correction (BLC) is a vital stage in the Image Signal Processing (ISP) pipeline. It is one of the components of the camera tuning process, and is usually performed after Dead Pixel Correction. BLC’s primary purpose is to remove sensor-generated offsets and noise present even without incoming light. In......
