Input Transforms

The Input Transform, sometimes called an Input Device Transform or IDT, converts non-color-rendered RGB image values from a given camera system or other image capture device to ACES RGB relative exposure values.

The responsibilities of an IDT include:

  • linearization,
  • white balancing,
  • clipping,
  • color analysis,
  • neutral chromaticity difference compensation, and
  • encoding as ACES RGB relative exposure values
