METHOD OF TRANSMISSION OF A VIDEO SEQUENCE OF IMAGES THAT HAVE TO BE COLOR TRANSFORMED USING LUT

摘要

Before the transmission of the source color values of the images of each group Gk of images of this sequence, a partial color transform LUT related to this group Gk is generated, then transmitted, - and, a resultant color transform LUT related to said group Gk is reconstructed by combining the transmitted partial color transform look up table of this group Gk with, if any, all the other partial color transform look up tables that have been previously transmitted, - then each images of said group are color transformed using this LUT. The invention allows a good precision of color transformation with a limited bandwidth.
