    This looks more like a host processor side configuration issue.

    Make sure your processor video port is configured for YUV422.

    Make sure that your processor display path is also configured correctly. Try forcing date into the display buffer for a known color and make sure it gets displayed correctly (i.e. the cyan cross in the middle of your example. I assume this is rendered to your display buffer after image capture? Is it being displayed in the correct color?

    What is your image source? Can you use a color bar test image from a DVD player? What does that look like?

    What is your wiring connectivity from the TVP digital output to the Leopard board? Is the wiring connectivity and Leopard board configuration correct?

    BR,
