title: MediaTek Media Data Path 3 Tone Curve Conversion



maintainers:

  - Matthias Brugger <matthias.bgg@gmail.com>



description:

  Tone Curve Conversion (TCC) is one of Media Profile Path 3 (MDP3) components.

  It is used to handle the tone mapping of various gamma curves in order to

  achieve HDR10 effects. This helps adapt the content to the color and

  brightness range that standard display devices typically support.
