Claim:
1. An image processor comprising circuitry configured to implement at least: a first acquirer that acquires a first perspective image of a target viewed at a first time, the first perspective image having a first resolution; a second acquirer that acquires a second perspective image of the target viewed at a second time different from the first time, the second perspective image having a second resolution; a first image generator that generates first and second display images from the first and second perspective images respectively, the first and second display images having a third resolution lower than at least one of the first and second resolutions; a first point acquirer that acquires a first point in the first display image and a first corresponding point in the second display image; and a first corrector that searches, in the second perspective image, based at least on part on pixel values in the first image and the second image, for a second image with a highest similarity to a first image in the first perspective image, the first image including the first point, and the first corrector corrects the position of the first corresponding point according to positional relation between the first and the second images.
