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.
