Parametric LUT Definition Methods

The advanced LUT API offers three parametric methods to specify the transfer function of the LUT operator: the Response control method, the Emphasis method and the Threshold method.

The user selects the LUT construction method by means of the LUT_Method parameter.

The same LUT definition method applies for all LUT devices belonging to a channel.

Controlling parameters associated with each parametric definition method

LUT_Method	Applicable parametric LUT building control parameters
RESPONSE_CONTROL	LUT_Contrast LUT_Brightness LUT_Visibility LUT_Negative
EMPHASIS	LUT_Emphasis LUT_Negative
THRESHOLD	LUT_SlicingLevel LUT_SlicingBand LUT_LightResponse LUT_BandResponse LUT_DarkResponse

All controlling parameters are of the "float collection" type. The dimension of the collection is equal to the number of LUT devices per LUT set.
