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.

Abstract: A method of processing a super resolution image using adaptive preprocessing filtering and/or postprocessing filtering is provided. A provided image processing apparatus may determine a preprocessing filter and a postprocessing filter based on frames included in a reference interval among a plurality of intervals in an input video, may perform filtering on the frames in the reference interval based on the preprocessing filter, may reconstruct a high frequency signal of each of the frames on which the filtering is performed, and may perform filtering on the frames, each having the reconstructed high frequency signal, based on the postprocessing filter.
