Abstract:
There are provided an imaging unit for capturing an image of a portion of a body surface of a living body with near-infrared light and generating near-infrared light imaging data, a vein pattern extraction unit for extracting a vein pattern from the near-infrared light imaging data by applying a differential filter, which outputs a large value for a pixel having a large difference between the pixel and its surrounding pixel, to a plurality of pixels constituting the near-infrared light imaging data, and a pseudo-vein pattern determination unit for determining presence of a pseudo-vein pattern intentionally formed on a part of the captured body surface based on the extracted vein pattern.
