Patent number: 8264325Abstract: 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.Type: GrantFiled: March 24, 2009Date of Patent: September 11, 2012Assignee: Fujitsu LimitedInventors: Mitsuaki Fukuda, Soichi Hama, Takahiro Aoki

Patent number: 8098302Abstract: An image pickup unit that does not have a movable system and is fixed at one point picks up an image. A subject region extraction unit detects a subject in the image, extracts a region of the subject, and generates a region extraction image. A region extraction image storage unit holds a plurality of recent region extraction images. Then, a stain level calculation unit compares the held region extraction images for each pixel, and increases a value of the stain level of a pixel when it is highly probable that a stain is present on the pixel, and vise versa. The subject region extraction and the stain level calculation are performed each time an image is picked up, and the value is updated. A stain determination unit outputs whether or not a stain is present and the degree that the stain is present on the basis of the value.Type: GrantFiled: December 8, 2008Date of Patent: January 17, 2012Assignee: Fujitsu LimitedInventors: Mitsuaki Fukuda, Soichi Hama, Takahiro Aoki, Toshio Endoh
