ov7670 blue red reversed if gamma is enabled. Any fix?

[human890209]

Hi,
I just start learning ov7670. I got it worked. But I want to enable the gamma function. But when gamma enabled, red and blue are swapped.
I tried to use the COM13 bit[0] to swap UV but it doesn't work.
I guess the UV swap is linked with bit[7] which is gamma enable by mistake.
Does anyone get a quick fix for this?

I don't want to fix this by software coding, cause I'm using ov7670 with Arduino Pro Mini which's power is very limited.

I had the same problem. I think you can fix it by changing how the data is processed on the computer. I am not sure. I have not ran this program in a few years.
