Color space conversion in PXP

udayakumar — Thu, 10 Aug 2017 11:17:25 GMT

We are using PXP in imx6ul through which we converted images from yuv to rgb, conversion worked properly and image was good. When we try rgb to yuv conversion the image is not as expected and it looks greenish, does CSC conversion registers in PXP should be handled separately for rgb to yuv conversion ?

We have tried with changing CSC2 coefficient registers to 1, but after that also the images are greenish only. Could you provide us the values need to be written in those registers for rgb to yuv conversion properly and other registers to be taken care?

Thanks,

Uday
