Hi,
We have a DM8148 based custom board, with EZSDK_5_05_02_00 and overlay code. We have a HD camera, which is connected to DM8148 using 16bit capture mode.
The camera can be configured either 720p/60 or 720p/30. We can capture the video in either mode if we don't use cropping (in that case, the captured image has lots of blank area). We can capture 1280x720 video with cropping if the camera is 720p/60.
The problem is, when the camera is 720p/30 and cropping is used, then the captured image is shifted to the right.
I attached the timing diagrams in both 720p/30 and 720p/60 and the images captured in each mode. The timing is pretty much the same for both modes. The difference is, in 720p/30, one H line consists of 3,300 pixel clocks. Those images were captured with the same exact settings, and only the camera mode was changed.
Can you think of any way to make the cropping work for this 720p/30 mode?
Since the camera doesn't generate 'Active Data' signal, we would like to use the cropping feature.
