Patent ID: 8305391

Claim:
A method for displaying images in a multiprimary display system using N colors, comprising: receiving a video input signal representation of pixel intensity and hue using M-dimensional color vectors, where M<N; determining an input gray scale weighting of the M-dimensional color vectors; converting the M-dimensional color vectors into (N-K)-dimensional and N-dimensional color vectors >+M-dimensional color vectors, including: if the determined weighting is less than a given threshold, converting the M-dimensional color vectors into (N-K)-dimensional color vectors, where (N-K)>=M, with the weightings of K of the colors set to zero; and if the determined weighting is greater than the given threshold, converting the M-dimensional color vectors into N-dimensional color vectors using weightings for all of the K colors; and displaying the image with the N colors using the (N-K)-dimensional and N-dimensional color vectors.
