ADV7182 creates dark line at bottom with NTSC input when ACE is ON


I am facing an issue with ADV7182 chip in NTSC input format where I can see the dark line at the bottom when ACE feature is ON.

This dark line is clearly visible in blue color in free-run mode. The same is visible even in actual NTSC blue color data.

This dark line issue at bottom is seen only with NTSC format when ACE feature is ON.

And the dark line at bottom is not observed with NTSC format when ACE feature is OFF.

I could not see any dependencies in datasheet regarding ACE, Please provide the solution for this issue.

Note: ACE means Adaptive Contrast Enhancement.
