Yes Picture is noisy. This is partly the fault of the sensor itself. Less noise than OV7610. Image is slightly underexposed.
Quality is very good though.
Yes Color is still not perfect, but picture is relatively free of noise. 352x288 max resolution. There might be a delay of a few seconds after starting capture before the image has stabilized and reached full brightness 3. Maybe Used in some OV518 cameras. It seems to be a 3.3 volt version of the OV6620.
