An image processing method is described which makes it possible to obtain an image which has a high quality and resolution without leaving boundaries of adjacent blocks detectable even in the case where the image has already been subjected to a processing of resolution enhancement (enlargement) of the image using a set of fractal parameters. The image processing apparatus 100 includes: an image division unit 114 which divides an input image IN into range blocks using L (L is an integer of 2 or more) numbers of division patterns so that at least one of the boundaries of each region in a division pattern varies from the boundaries of each region in the other division patterns; a parameter calculation unit 103 which calculates a set of fractal parameters of each range block of the input image IN so as to obtain L numbers of fractal parameters; an image transformation unit 107 which generates L numbers of fractal transformed images using, one by one, the modified sets of fractal parameters obtained according to enlargement ratios; and an image synthesis unit 112 which synthesizes the L numbers of transformed images so as to generate a single synthesized image. The image transformation unit 107 and the image synthesis unit 112 repeat the transformation and synthesis using in sequence the respective sets of fractal parameters until this synthesized image satisfies the convergence condition.
