An image processing method includes the steps of obtaining information on periodicity in a direction of rotation of at least one of a template image and an image to be searched, carrying out first matching in respect to the direction of rotation between the template image and the image to be searched and determining a plurality of candidates for an amount of rotation for correcting relative displacement in direction of rotation between the template image and the image to be searched based on a result of first matching and the information on periodicity, generating a plurality of sets of images resulting from correction of relative displacement in direction of rotation between the template image and the image to be searched with each of the candidates for the amount of rotation, and carrying out second matching in respect to a position in each of the sets of images and outputting a result relatively high in likelihood, among results of second matching. |
