Abstract
The present invention provides an image encoding apparatus carrying out inter-color prediction, comprising a residual block acquisition module obtaining a residual block with respect to a first color component and a residual block with respect to a second color component from a difference between an input block and a prediction block; an inter-color component prediction module carrying out inter-color component prediction by generating a residual signal reflecting a difference between a residual block with respect to the first color component and a residual block with respect to the second color component; a transform module generating a transformat coefficient by carrying out transformation with respect to the residual signal; a quantization module generating quantized data by carrying out quantization with respect to the transform coefficient; and an entropy encoding module carrying out entropy encoding by removing statistical redundancy of the quantized data.
