ABSTRACT:
It is controlled by a non-transformation coefficient calculated by a non-transformation calculation section, whether feedback is performed or not. When the feedback is ended, a collation value calculation section calculates a collation value (coincidence coefficient×non-transformation coefficient). A display process section compares the collation value with a predetermined threshold value. When the collation value is a threshold value or more, a signature is decided as a true signature, and the transformation-corrected image and the reference image are displayed such that these images overlap.
