Abstract
The present invention relates to an image processing method and apparatus for processing compressed image generated by segmenting image data into a plurality of MCUs and using a compression method in which a frequency transformation is applied to each MCU. In a case that the compressed image is decoded, each MCU is classified according to the frequency coefficients therein, and color separated data is generated for each MCU based on the decoded data resulting from the decoding and the results of the MCU classification.
