Abstract:
1. A biometric image collation apparatus comprising: an image quality priority level decision processing unit which evaluates a magnitude of an image quality of each of a plurality of first image data formed from biometric images associated with the same target on the basis of a specific index having a relationship of a monotone function with authentication accuracy of biometric authentication, and outputs each of the first image data upon adding a priority level thereto on the basis of the evaluation result, wherein said image quality priority level decision processing unit comprises: a first image storage unit which stores each of the first image data having a priority level added thereto from said image quality priority level decision processing unit; a second image storage unit which stores second image data used for comparison/collation with the first image data; an image collation unit which compares/collates the second image data stored in said second image storage unit with the first image data stored in said first image storage unit and outputs the comparison/collation result; and a control unit which controls each of said units wherein said control unit causes said image collation unit to compare/collate the second image data stored in said second image storage unit with the first image data stored in said first image storage unit in accordance with the priority levels, and outputs the comparison/collation result from said image collation unit.
