Abstract: High-accuracy multimodal biometric authentication of a plurality of body organisms is achieved while suppressing postural fluctuation when the plurality of body organisms are captured. An authentication system stores feature quantities for body organisms in association with users and performs biometric authentication on the basis of images from a capture device. The capture device photographs a first body organism of a first user during a first period and captures a second body organism and a third body organism of the first user during a second period. The authentication processing device calculates a first feature quantity from the first body part photographed during the first period, respectively calculates a second feature quantity and a third feature quantity from the second body organism and the third body organism captured during the second period, and compares with the feature quantities for the body organisms of each user stored at the storage device.

Abstract: An upstream integrated value is an integrated value of a difference obtained by subtracting an upstream gas temperature at a starting point in time of integration from the upstream gas temperature after starting of the internal combustion engine. A downstream integrated value is an integrated value of a difference obtained by subtracting a downstream gas temperature at the starting point in time of the integration from the downstream gas temperature after the starting of the internal combustion engine. An anomaly diagnosing process obtains an anomaly determination result indicating that the exhaust purification device is in a removed state when a deviation between the upstream integrated value and the downstream integrated value is smaller than a reference level. The determination threshold is higher than a dew point.

Abstract: 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.
