摘要

video encoding and decoding method, devices for them, programs for them, and storage medium that stores the programs. the present invention relates to a method of video encoding which includes establishing reference pixel candidates for pixels within a predetermined distance range measured from a target encoding block; generate a predicted signal by sequentially selecting reference pixels used for the intra prediction of the target coding block among the candidate reference pixels, while changing a distance condition from the coding target block, and by generating the predicted signal based in the reference pixels for each distance condition; calculating a coding cost required to subject the target coding block to intra prediction coding using each intra prediction signal of the target coding block based on each calculated coding cost; and encode information that indicates the position of the determined reference pixels.
