Abstract
A fingerprint recognition device includes a memory and a processor. The memory is configured to store at least one command. The processor is configured to read the at least one command to execute following steps: dividing a fingerprint image into a plurality of sub-areas; classifying the plurality of sub-areas into a plurality of high-quality areas and a plurality of low-quality areas according to a grayscale value ratio of the plurality of sub-areas; obtaining a first feature sample of the plurality of high-quality areas; obtaining a second feature sample of the plurality of low-quality areas, wherein a number of the first feature sample is larger than a number of the second feature sample; and outputting the first feature sample and the second feature sample.
