摘要： An image forming apparatus causes an illuminating unit and an imaging unit to equally split a predetermined exposure time into a plurality of split exposure times, and acquire an image with illumination and an image without illumination in each of the split exposure time. A luminance difference image for a particular split exposure time is calculated by subtracting the image without illumination from the image with illumination of the exposure time. The luminance difference images of all the split exposure times are integrated.

摘要： In accordance with input user ID, a personal template fetcher reads biometric feature data and biometric shape data from a template storage. A verification area finder determines a verification area that matches a detection area of a verification sensor within an area of biometric features. A guide information generator combines the verification area with a contour shape reconstructed from the biometric shape data, received from the personal template fetcher, to generate a guide pattern. A guide information presenter presents the generated guide pattern to the user. A verification sensor extracts biometric feature information from an input image of biometric features and converts it into numeric data to obtain biometric feature data. A biometric feature verifier then verifies the biometric feature data obtained by the verification sensor in comparison with the biometric feature data received from the personal template fetcher in the verification area received from the verification area finder.
