Thanks, the captured image is correct but it is in YVUV format. By default the display is configured for UYVY, therefore luma and chroma are swapped. You need to change display settings.

How to change? do I need to insert a color convert node? or just change settings.

What's the data format used in sensor driver? You would have specified something like VX_DF_IMAGE_UYVY in IssSensor_CreateParams. Please try changing that.

Yes, we set camera format to VX_DF_IMAGE_UYVY , and also tried VX_DF_IMAGE_YVYU, but neither of them works. Seems the display doesn't support. we will try to add a color convert node. Thank you.
