  • Patent number: 8264325
    Abstract: 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.

  • Patent number: 8098302
    Abstract: 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.

  • Publication number: 20090261947
    Abstract: 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.

  • Publication number: 20090220141
    Abstract: A blood vessel imaging device obtains peak height information of a differential function F?(x) from an adjustment dial. The blood vessel imaging device, based on the peak height information and peak position information of the differential function F?(x), then defines the differential function F?(x). Subsequently, the blood vessel imaging device calculates an LUT function F(x) that indicates the shape of an LUT by integrating the defined differential function F?(x). The blood vessel imaging device generates an LUT based on the LUT function F(x). The blood vessel imaging device reads out a picked-up image stored in a picked-up image memory, converts a luminance value of the picked-up image being read using the LUT, and displays the image with the converted luminance value.
