摘要：A method of gamma correction includes selecting lower and upper referencecurves corresponding to selected reference gamma values. A gamma correction curve is
generated from a corresponding gamma correction value and cross-correlated with theupper and lower reference curves to generate a corresponding set of cross-correlationfactors. The set of cross-correlation factors are stored and indexed to the correspondinggamma value. An input value is received for gamma correction with the correspondinggamma value. Data from the upper and lower reference curves indexed by the input valueare then operated one with the cross-correlation factors to generate a gamma correctedoutput value.
