Abstract:
A method for mapping an input grayscale into an output luminance includes selecting a first reference grayscale, a first reference luminance, a second reference grayscale and a second reference luminance according to an input grayscale, generating a middle reference grayscale and a middle luminance, replacing a value of the first or second reference grayscale by a value of the middle reference grayscale, and replacing a value of the first or second reference luminance by a value of the middle luminance according to the middle reference grayscale and the input grayscale, and generating an output luminance by computing a linear transformation equation.
