Abstract
The present invention concerns a method of encoding an image, the image comprising a plurality of coding elements made of blocks of pixels, each block of pixels being encoded according to a coding mode out of a plurality of coding modes, the method comprising for each block of pixel to be encoded determining the coding mode to be used for the encoding of a given block of pixels by sequentially evaluating some coding modes in the plurality of coding modes; wherein the method comprises evaluating Inter coding modes and fast IBC coding modes; and no residue-test is conducted between the evaluation of the Inter coding mode and the evaluation of the fast IBC mode. Accordingly, some good predictors may be found more rapidly and the whole encoding process is speed up.
