An image comparison apparatus is assumed to receive fingerprint data in accordance with one of a sweep sensing method and an area sensing method. In operation when the image comparison apparatus receives an image the apparatus calculates a value of an accumulation of movement vectors obtained between such input images and in accordance with the calculated cumulative value determines a fingerprint inputting and comparing method (or a sensing method), and in accordance with one of the methods calculates similarity between an input fingerprint image and a read reference image and as based on a result of the calculation compares the fingerprint image with the reference image. In accordance with a result of determining a method and a result of comparing the images a symbol for information is generated.
