Abstract
A dictionary image renewing method in a fingerprint identification device registers images into a dictionary memory as multiple dictionaries. The method includes extracting images from a plurality of fingerprint images determined as being acceptable identification by mutual identification and using the multiple dictionaries to perform identification processing of entered fingerprint images. This includes successively identifying by comparing entered fingerprint images with the dictionary images registered in the multiple dictionaries, and when identification acceptance results with any one of the multiple dictionaries the one dictionary determined as being identification accepted is renewed to the dictionary image registered in any one of the remaining dictionaries. The remaining multiple dictionaries are renewed to the dictionary image extracted from the entered fingerprint images.
