Color Correction in imx6 IPU

sandheepkumar — Fri, 03 Jun 2016 06:43:52 GMT

Hi All,

I am currently working in a custom imx6-sabresd board, where I need to apply a color correction matrix to an input RGB frame. I would like to implement this color correction in IPU. From the reference manual, I found that IPU supports RGB to RGB conversion. The conversion process can be tuned using a color conversion matrix whose values are stored in IC Task Parameter memory.

Can I do this conversion using IPU Task? If means, can anyone provide me an example of how to implement it ?

Regards,

Sandheep

Hi Igor,

In the first link, Gamma correction is implemented directly in framebuffer. In my case, I don't require framebuffer.

In the second link, I found the solution for my problem but I would like to implement those CSC matrices in IPU.
Is there any reference for it ?
