Abstract:
In accordance with at least one embodiment, a first representation of a first gamma curve is stored in a look-up table, a second representation of a second gamma curve is stored in a look-up table, and a video signal is modified in accordance with an interpolation of at least a portion of the first representation of the first gamma curve and at least a portion of the second representation of the second gamma curve. In accordance with at least one embodiment, the at least a portion of the first representation of the first gamma curve is multiplied by a one's complement of a normalized weight factor, the at least a portion of the second representation of the second gamma curve is multiplied by the normalized weight factor, and the results are added together to obtain an output video signal.
