WebSep 30, 2024 · Please let me ask one question about the behavior of Black Level Clamping (CLPOB) on ADDI7018. My understanding is that this CLPOB is the function only to subtract an average value of the optical black pixels from the effective image pixels on every line. Is it correct? Or any kind of advanced digital filtering is implemented inside? Thank you. WebSolving The Black Bar – Top or Bottom.
