<P>PROBLEM TO BE SOLVED: To provide an apparatus for generating chrominance shape information capable of effectively representing objects in a video object plane (VOP). <P>SOLUTION: In the apparatus that generates chrominance shape information based on luminance shape information of a matrix configuration, each component of the matrix is represented by one of two different logic values, wherein the logic values respectively represent the outside and the inside of the object in the video object plane. The apparatus includes a means for dividing the luminance shape information into a multiplicity of sample blocks, each of which includes 2×2 pieces of components, a means for determining one logic value for the chrominance shape information, based on the logic values of the luminance shape information in each sample block; and a means for generating the chrominance shape information of a matrix configuration, based on the logic value of each chrominance shape information for all the sample blocks. <P>COPYRIGHT: (C)2007,JPO&INPIT |
