Biometric authentication system, biometric authentication method, and storage medium

The objective is to achieve highly accurate authentication even when there is variation in the ambient light environment during biometric imaging. A biometric authentication device includes an image capturing unit that captures images of a living body, a light source for capturing images of the living body, an optical filter that selectively passes and blocks light according to wavelength, a spectroscopic processing unit that separates multiple wavelengths captured simultaneously, respectively, and a calculation unit that calculates the shape and posture of a predetermined part of the living body in the captured images, a background removal unit that removes the background from the image of the living body using the spectral images of the living body and the spectral image of the unwanted ambient light, and an authentication unit that performs biometric authentication using the image of the predetermined part.

Biometric authentication device and biometric authentication method

To provide an imaging device capable of reducing discomfort caused by visible light. A light source can emit the visible light and invisible light as irradiation light. An imaging unit captures an image of an irradiation region irradiated with the irradiation light to acquire an image. A processor causes the imaging unit to acquire a detection image in a first irradiation mode in which the invisible light is emitted from the light source, and determines whether a biometric object is presented in the irradiation region based on the detection image. When the biometric object is presented, the processor causes the imaging unit to acquire the biometric image obtained by copying the biometric object as the image in a second irradiation mode in which the visible light and the invisible light are emitted from the light source.

Imaging device, authentication device, and biometric imaging method

A head-mounted display (HMD), which is operated by a gesture operation performed by a user, is provided with a distance image acquisition unitthat detects a gesture operation, a position information acquisition unitthat acquires position information of the HMD, and a communication unitthat performs communication with another HMD'. A control unitsets and displays an operating spacewhere a gesture operation performed by the useris valid, exchanges position information and operating space information of the host HMDand the other HMDtherebetween by the communication unit, and adjusts the operating space of the host HMD so that the operating spaceand an operating spaceof the other HMDdo not overlap each other.

It is provided a biometric authentication system, which is configured to execute authentication by using registered biometric information, the biometric authentication system comprising: a light source unit configured to irradiate a living body with light; an image pickup unit configured to photograph a vessel image with light radiated from the light source unit and transmitted through the living body; a control unit configured to generate authentication biometric information from the vessel image photographed by the image pickup unit; a category selection unit configured to select a category that corresponds to the authentication biometric information, based on supplementary information including information that has been obtained about a position and posture of the living body at timing of photographing the vessel image; and an authentication unit configured to execute authentication processing by comparing registered biometric information of the selected category and the authentication biometric information.

Biometric authentication system

A branch predictor for predicting an instruction to be executed next to a conditional branch instruction in a program to read the predicted instruction beforehand. The branch predictor includes a hint acquisition section for acquiring a hint when a specified instruction controlling acquisition of the hint is executed wherein said hint indicates whether a branch is to be taken by execution of a conditional branch instruction with which termination of a loop is judged. The branch predictor further includes a hint store section for storing the hint acquired by the hint acquisition section, and an instruction read section for reading an instruction predicted as executed next to a conditional branch instruction in accordance with the hint stored in the hint store section. According to the invention it is possible to accurately predict a branch at the time of loop termination of the loop termination judging conditional branch instruction.
