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.
