摘要： The present invention relates to a method for renewing dictionary image data in a fingerprint identification device, and enables to shorten dictionary identification time and to always keep the dictionary images in the best condition. And, the invention also relates to a dictionary registration and identification method for a fingerprint identification device, by which an identification rate is improved by registering and identifying a plurality of dictionaries. Besides, the invention relates to a method for judging fingerprinting in a fingerprint identification device, by which continuous identification rejections can be prevented. The invention relates to a fingerprinting judging method in a fingerprint identification device, which can prevent misjudgment in fingerprint identification. In a dictionary image renewing method in a fingerprint identification device according to the present invention, match data is provided in respective minutia data to indicate the number of times of matching with an entered fingerprint image, and when pattern matching is performed between all minutia data and entered fingerprint images for a prescribed period, respective minutia data configuring the dictionary data can be arranged in the order from the greater match data.

摘要： 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.
