I have an image sensor problem and I am looking everywhere to identify the problem but couldn't. Attached is the problem I observe. As you can see there are several horizontal lines in the image.
So far, I have checked power, clocks and all seems in order. Appreciate any ideas you may have. (If I get a test image from sensor-diagonal tiles etc-, all seems to be good. So, I am assuming it is not communication with the sensor. Sensor datasheet is here)
I am not looking for a specific answer but more of a direction and/or ideas. Somebody with the right experience could know where to look.
Apparently this type of problems can be observed in other sensors. See the link.
I have realized, I missed out one critical information, if I reduce the clock frequency of the sensor the problem disappears. So there is a clock frequency dependency. However I do not suspect read out since if I set the test pattern, regardless of frequency all is good.

After further testing, I figured the problem is same in every frame. Previously, I was wrong. Here is the 4 images from different times. Images are stiched together, all 480x752
