An image processing apparatus for searching for corresponding points between a first image and a second image is provided. The image processing apparatus includes window setting means for setting a window for each of the first image and the second image, phase information extraction means for extracting phase information by subjecting a representation included in each set window to frequency decomposition, corresponding points determination means for determining corresponding points between the first image and the second image based on comparison of the phase information extracted from each window, and window size control means for causing the window setting means to set a window different in size in accordance with a frequency used for calculation of the frequency decomposition. The window size control means causes the window setting means to set a window having a first size in response to a first frequency and to set a window having a second size smaller than the first size in response to a second frequency higher than the first frequency. |
