Zusammenfassung:PROBLEM TO BE SOLVED: To allow a maker of a fingerprint collating device and a buyer to mutually perform appropriate performance confirmation by appropriately evaluating fingerprint quality of a person. SOLUTION: When a fingerprint evaluating device is connected to a fingerprint sensor 20 that is the same with the fingerprint sensor of a fingerprint collating device to be an evaluation object and a fingerprint picture is acquired, a moment matrix calculating part 33 differentiates the fingerprint picture to prepare a moment matrix, a skin ridge direction reliability calculating part 34 calculates skin ridge direction reliability from its singular value, a picture quality calculating part 35 calculates the average value of the skin ridge direction reliability within a fingerprint area as picture quality and displays the average value on a displaying part 32.
