Abstract
Methods and apparatuses for performing lossless normalization of input pixel component values. The apparatus includes a normalization unit for converting pixel values from a range of 0 to (2−1) to a normalized range from 0.0 to 1.0. The step size between adjacent values of the normalized range is 1/(2−1), and a maximum input value of (2−1) corresponds to a normalized value of 1. The normalization unit divides each input pixel component value by (2−1) in order to preserve the fidelity of the color information contained in the input pixel component value.
