An image processing apparatus acquires at least first and second input images corresponding to the input image and having a first resolution and a second resolution higher than the first resolution, respectively, acquires first and second reference images corresponding to the reference image and having resolutions corresponding to the first and second resolutions, respectively, calculates a relative displacement of rotation and/or scale between the first input image and the first reference image through a search process between the first input image and the first reference image, corrects the first reference image based on the relative displacement to generate a first corrected reference image, determines a corresponding position in the first resolution through a search process between the first input image and the first corrected reference image, and determines a corresponding position in the second resolution by performing a search process between the second input image and the second reference image, using the relative displacement, with reference to a position in the second input image that is equivalent to the corresponding position in the first resolution. |
