Abstract

A color image encoding and decoding method and apparatus use a correlation between chrominance components in order to improve coding efficiency. The color image decoding method includes: transforming chrominance components of a color image in each of two or more inter-prediction modes, calculating costs for the conversion values in each of the two or more inter-prediction modes using a predetermined cost function, selecting one of the two or more inter-prediction modes based on the calculation result, and outputting conversion values of the selected inter-prediction mode; entropy encoding the output conversion values.
