Abstract: A method and an encoder device for generating an inverted lookup table (LUT). The method may identify monotonic and/or non-monotonic parts of a non-monotonic LUT. The method may generate a first plurality of data points by measuring the non-monotonic LUT in ascending order. The method may generate a second plurality of data points by measuring the non-monotonic LUT in descending order. The method may compute an average value by averaging the first plurality of data points and the second plurality of data points. The method may generate the inverted LUT based on the average value.
