Color distorted image from the camera interface

Hi,

I have the DM365 VPFE processing OV7648 sensor based CCDC camera. The video captured is appearing with color distortion as below. Any hints?

OV7648 is configured to give YUV 4:2:2 format on 8-bit data interface.

 

Thanks in advance!

    I suspect the data input as bright and dark are repeated (this means either data line is not properly connected in order or some lines are in short circuit).

    Please check whether some data lines are in short circuit.

    I assume you have proper basic setting such as input mode (YUV instead of RAW).

     

    regards,

    Thanks Sang-Yong for the hint!

    We found out that the lower four lines of data-out from the camera sensor are not connected to the DM365 ISIF interface. Now, with this connection, the image is captured correctly.

     

    Thanks a ton!

    Panch!
