This is often used with a histogram to ensure the full use of the camera bit-depth, effectively raising signal-to-noise. Pushing non-black pixels to zero lightens the image, although it gives no improvement in the data. WebDec 16, 2024 · In the active pixel array, there are active pixel areas and OB (Optical Black) pixel area, and in OB region, there are 2-4 rows of drain pixels where all nodes are connected to Vdd. I am kind of guessing that the purpose of having those pixels is for blocking electrons between the active area and OB area. I am not sure. hurst now review
