摘要： A biometric authentication device includes: a biometric information acquisition unit which generates a first input biometric image representing the biometric information of a user, a storage unit which stores data relating to registered biometric information of at least one registered user, and a processing unit. The processing unit realizes a quality judgment function which judges if the first input biometric image is suitable or not for use for comparison of the biometric information represented in the first input biometric image with the registered biometric information, a selection function which selects registered biometric information which is similar to biometric information represented in the first input biometric image among registered biometric information when the first input biometric image is judged unsuitable, and a matching process function which compares the user's biometric information represented in a second input biometric image with the selected registered biometric information.

摘要： A photographing section photographs a photographing object, a light-projector projects a light spot parallel to or approximately parallel to an optical axis of the photographing section onto the photographing object, and a detector detects, from an image of the photographing object photographed by the photographing section, a light spot from the light-projector reflected by the photographing object on the basis of an arrangement position of the light-projector relative to the photographing section. A reflected light spot of light projected onto a detection object can be detected with certainty, and erroneous detection of the reflected light spot, in particular, erroneous detection due to disturbance light, can be prevented at a low cost, without an increase in size of the apparatus.

摘要： Disclosed is an authentication apparatus easily achieving convenience and high accuracy in authentication. The authentication apparatus has an authentication accuracy simulation section that simulates authentication accuracy and also has a registration information setting section that sets an ID and biometric information input as registration information. The authentication accuracy simulation section uses an ID and biometric information that has been input as registration information by a user at the time of registration and the registered registration information to simulate authentication accuracy with which the user is authenticated. When the authentication accuracy simulated by the authentication accuracy simulation section does not satisfy a predetermined condition, the registration information setting section rejects registration of the ID input as the registration information.

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.
