1. An image processing apparatus for executing a plurality of image processings for an objective image, comprising: a decomposition unit for decomposing the objective image into components of a plurality of frequency bands; an analysis unit for analyzing the components obtained by said decomposition unit with respect to each of the plurality of image processings; a component conversion unit for converting the components obtained by said decomposition unit on the basis of analysis results of said analysis unit; and an image generation unit for generating an image, after the objective image has undergone the plurality of image processings, from the components of the plurality of frequency bands converted by said component conversion unit.
