REGISTRATION APPARATUS, REGISTRATION METHOD AND PROGRAM

A registration apparatus includes: a calculation section that calculates a positional difference between a part of a physical trait on a first image that is processed and a corresponding part of the physical trait on a second image that was processed earlier than the first image, the physical trait being used for verification; a connecting section that connects the first image to the second image after correcting, in accordance with the calculated positional difference, the position of the first image such that a part of the physical trait on the first image is overlapped with a corresponding part of the physical trait on the second image; and a registration section that registers the connected image in a storage medium.
