Definitions
- a method is related for transmitting and using metadata that relates the order of color correction operations to be performed on image data representing a sequence of images and the number of such operations to be performed on such image data.
- a ColorLookupi D color correction operation preferably consists of three 1-D look up table for each color component.
- the quantization of the input color space equals the number of entries in the look up table. In this case, no interpolation is required. It is however possible for a 1-D color look up table to contain fewer entries than the input color space. For example, consider an RGB input color space with 6-bit color quantization and 16 entry look up table for each color component. The values of input values can be narrowed down to match the finite number of output values using interpolation techniques as known in the art.
- Gain (G) scales the output value.
