FILM GRAIN SYNTHESIS

A device includes a memory configured to store film grain information. The device also includes one or more processors coupled to the memory and configured to downscale a first image frame having a first resolution to obtain a second image frame having a second resolution. The one or more processors are also configured to obtain, based on the film grain information, film grain data associated with the second resolution. The one or more processors are configured to output an output image frame based on the second image frame and the film grain data.
