A technique for correcting an image by using frequency division images and decomposition images corresponding in number to reference points is disclosed. An image correction apparatus includes an image divider which divides an inspection reference image into frequency regions to form frequency division images, a decomposition image generator for defining reference points at several locations within at least one frequency division image and for applying weighting with each reference point as a reference to thereby generate decomposition images corresponding in number to the reference points, a model parameter identifier for identifying a model parameter by using 2D linear prediction models of an image being tested, the decomposition images and a frequency division image which is out of the generation of decomposition images, and a model image generator for using the model parameter to generate a model image. An image inspection apparatus using the correction apparatus and an image correction method are also disclosed. |
