A method performed by a computer for biometric authentication includes: obtaining, by a processor of the computer, a first image group including a plurality of images that are sequentially captured by a biometric sensor configured to capture at least a part of a region of a body of a user; obtaining, by the processor of the computer, a movement amount of the body and a distance between the body and the biometric sensor; and selecting, by the processor of the computer, a second image group from the first image group in accordance with the movement amount and the distance, the second image group including images to be used in authentication processing with respect to the body, wherein the size of a common region between images to be included in the second image group is adjusted according to the distance.

Device, method, and non-transitory computer-readable storage medium for biometric authentication

A biometric image processing apparatus including a memory and a processor coupled to the memory. The processor obtains a Y value, a U value and a V value in a YUV space from each pixel of an image, determines, for each pixel, whether or not the U value and the V value are in a range that is in accordance with the Y value, and extracts a pixel having been determined to be in the range.
