We are capturing from CVBS camera with single ended configuration using ADV7182. Frames are captured properly on the processor with de-interlacing .But the captured frames are not sharp and we can see black colored pixels on the low lit(intensity) areas.
We did not doubt on the processor software as the same code was running good with Intersil TW9966. How can we make the frame sharper without any dark spots.
P.S. Have attached the captured frame for referance. Please see on the eye,chin areas of the person in the frame.these areas are black colored and overall the frame quality is not good.
