UPDATE:
The above image was fixed by changing from Right Justified to Even Distributed.
But I have a small issue. I was able to switch the Cr and Cb signals to make the image look better; but I can only get the correct color output when I first toggle register 0x18 (CSC ENABLE), run the code, then toggle register 0x18 (CSC DISABLE) again and only then the image shows perfectly fine. If I run the code with CSC Disabled without prior toggling, the image looks very similar to what is above. Any way to fix this?
