BIOLOGICAL IMAGE CORRELATION DEVICE AND CORRELATION METHOD THEREOF

摘要

A biological image correlation device includes: an image quality priority decision section (40) for evaluating image quality for each of a plurality of first image data consisting of biological images relating to the same object, according to a particular index which is in relation of a monotone function with verification accuracy of biological verification, assigning priority to each of the first image data according to the evaluation result, and outputting them; first image storage sections (6, 81) for storing the first image data to which the priority is assigned and output from the image priority decision section (40); second image storage sections (8, 61) for storing second image data used for comparison and correlation with the first image data; an image correlation section (7) for comparing and correlating the reference image data stored in the second image storage section with the first image data stored in the first image storage sections (6, 81) and outputting the comparison/correlation result; and a control section (9) for controlling the aforementioned components. The control section (9) makes the image correlation section (7) compare/correlate the second image data stored in the second image storage sections (8, 61) with the first image data stored in the first image storage sections (6, 81) according to the aforementioned priority and output the correlation result from the image correlation section (7).
