摘要
A method for generating a reduced image of an original image comprising blocks encoded by intra prediction, and an image apparatus thereof are provided. The method for generating a reduced image, includes extracting an average of a compression block of a compression image, the compression image including blocks encoded by intra prediction; computing an average of a prediction block, using a portion of components of at least one of neighboring blocks to the prediction block corresponding to the compression block; and generating a reduced image using the average of the compression block and the average of the prediction block. Therefore, a reduced image of an original image can be generated without decoding blocks of the original image comprising blocks encoded by intra prediction.
