we are using ad9920a+kai-02150.the left and right edge (about 100 pixel) of the image are more bright than the center part under low-light scene. we disable the clpob. when we set the clamp level to 0,the phenomenon is weak，to 3ff obvious. the hardware or the setting of ad9920 is not right? who can give some advice and explanation about the black clamp of the AD9920A?
