Abstract
An apparatus generates chrominance shape information based on luminance shape information represented by binary values, to thereby describe an object in a video object plane effectively. The apparatus divides the luminance shape information into a multiplicity of sample blocks, a sample block including 2.times.2 pixels, and determines, for each sample block, a chrominance value based on all logic values in a sample block. The chrominance shape information is produced in a form of a matrix based on the chrominance values for all sample blocks.
