AD9984A - loss of details on dark image

I have an issue with image acquisition on my own video acquisition board equipped with AD9984A. The picture is almost all filled with black color with only few lines of gray. When I capture the image the gray lines are only partially visible. But when I increase source image brightness (on PC, using image editor) and capture the brighter image then everything looks fine. So the issue is only for dark images.

On the other hand I use my system to capture tons of gigabytes of video data and I haven't noticed any other issues except this one.

Do you have any idea what is going on?


You will find source and captured images below.
