An iris recognition apparatus is provided with: an irradiating device that is capable of irradiating light to a target person to be recognized; an acquiring device that acquires a first image which imaged a first imaging range including at least a face of the target person; and a determining device that determines an irradiation mode of light irradiated from the irradiating device to the target person when imaging a second image including an area, which includes an eye of the target person, and corresponding to a second imaging range, which is narrower than the first imaging range, based on the first image.

Iris recognition apparatus, iris recognition method, computer program and recording medium

An illumination control apparatuscomprises: a detection unitthat detects an iris area IA and a reflection area RA in an eye image IMG_E generated by imaging eyes of a target being illuminated with illumination light IL from an illumination apparatus, the iris area IA and the reflection area RA corresponding to an iris of the eyes and a reflection image of the illumination light respectively; and an illumination control unitthat controls the illumination apparatus based on an overlap state between the iris area and the reflection area.

Controlling illumination apparatus based on overlap state between iris area and reflection area

An imaging apparatus for authentication includes: a first imaging unit that obtains a first image used in a first authentication process by imaging a target person; a second imaging unit that obtains a second image used in a second image process by imaging the target person in an imaging range narrower than that of the first imaging unit; a drive unit that integrally drives the first imaging unit and the second imaging unit; and a drive control unit that controls the drive unit on the basis of the first image.

Imaging apparatus for authentication and authentication system

An imaging system () includes: iris imaging means () for photographing an iris of a subject; first irradiation means () for applying light to the subject; and second irradiation means () for applying light to the subject in such a manner that an angle between an optical axis of the light emitted from the second irradiation means () and an optical axis of the iris imaging means () is larger than an angle between an optical axis of the light emitted from the first irradiation means () and the optical axis of the iris imaging means ().

Imaging system, imaging method, and computer readable medium

An information presenting system includes: a specification unit that specifies a position of a biological part used for authentication from information about a target person; a setting unit that sets an imaging area in which the biological part is imaged, in accordance with the specified position of the biological part; and a presentation unit that presents information indicating the imaging area at a position that allows an overlap of the biological part. According to this information presenting system, information about biometric authentication can be appropriately presented to the target person, so that an authentication process can be performed normally.

Information presenting system, information presenting method, computer program, and authentication system

An information processing system () comprises: a distance acquisition unit () that specifies an iris area containing an iris of a target from a visible-light image of the target, and acquires an iris distance that is a distance to the iris area; an iris image acquisition unit () that acquires an iris image of the target by changing a focal length according to the iris distance; a score computing unit () that calculates a score relating to deviation of a focus in the iris image, based on the iris image; and a correlation update unit () that updates correlation between the iris distance and the focal length at a moment of acquisition of the iris image, based on the score. According to such an information processing system, since the correlation is updated with good accuracy, it is possible to acquire the appropriate iris image.

Information processing system, information processing apparatus, information processing method, and recording medium

An illumination device emits light toward a moving subject. A controller controls light emitted from the illumination device so that the amount of light applied to the subject is adjusted to a specific amount or smaller. For example, when the illumination device emits light in a pulsed manner, the controller may control the amount of light applied to the subject by controlling at least one of the pulse width and the pulse intensity of the light. The controller may, for example, control the light emitted from the illumination device according to the distance between the illumination device and the subject.

Illumination control apparatus, method, system, and computer readable medium

An information providing device according to one aspect of the present disclosure includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: receive a face image; determine whether a person in the face image is unsuitable for iris data acquisition based on the face image; and output information based on determining that the person is unsuitable for the iris data acquisition when the person is determined to be unsuitable for the iris data acquisition.

Information providing device, information providing method, and storage medium

An information processing apparatus () includes: an extracting unit () that extracts a key point (KP) of a target object as a target key point (KP) from an input image (IMG); and a calculating unit () that calculates, as a score (SC) of the input image from which the target key point is extracted, an index value related to a reliability of the target key point based on the target key point.

Processing apparatus, information processing method and recording medium

The optical control apparatus includes a light source, a light collecting section, and an optical path control section. The light source emits light. The light collecting section collects the light emitted from the light source and illuminates the light onto an object.

Optical control apparatus and optical control method

To provide a system, a method and the like for acquiring more images or more quickly focused images. A control device acquires information regarding a situation of a range captured by an imaging device, determines a mode according to an assumed situation of the range captured by the imaging device among a plurality of focusing modes, and transmits designation information specifying the determined mode to the imaging device. The imaging device receives the designation information from the control device, and captures an image using the mode specified by the received designation information.
