An image input device inputs image sequence data. A memory stores each image of the image sequence data. A tracking point indication unit initially indicates a plurality of tracking points on a first image stored in the memory. A pattern matching unit compares a pattern of each tracking point of the first image with a second image stored in the memory, and detects a plurality of destination candidate points from the second image, each corresponding to each tracking point. A position inconsistency correction unit decides whether a positional relation of the plurality of destination candidate points is consistent with a positional relation of the plurality of tracking points, and corrects at least one of the plurality of destination candidate points on the second image if the positional relation of the plurality of destination candidate points is inconsistent with the positional relation of the plurality of tracking points.
