摘要

To accurately show the size of a standard resolution on an image of a fingerprint. A device comprises: a starting point setting unit (12) which, according to a starting point specification instruction that is input on a scale included in a fingerprint image, sets a starting point on a pilot wire that is specified first by the starting point specification instruction out of pilot wires of divisions on the scale; a passage point setting unit (13) which, every time an input line that is drawn along the scale from the starting point passes a pilot wire, sets a passage point on the passed pilot wire; an inter-division distance calculation unit (14) which calculates an inter-division distance on the image using the position of the starting point and the position of the passage point; a standard resolution calculation unit (15) which calculates the size of a standard resolution that corresponds to the image using the inter-division distance and a unit length which is the length of one division in the scale; and a frame display unit (16) which displays a frame on the image so as to match the size in the standard resolution.
