    Abstract: An imaging system (10) includes: iris imaging means (1) for photographing an iris of a subject; first irradiation means (2a) for applying light to the subject; and second irradiation means (2b) 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 (2b) and an optical axis of the iris imaging means (1) is larger than an angle between an optical axis of the light emitted from the first irradiation means (2a) and the optical axis of the iris imaging means (1).

    Abstract: The image acquiring device 10 includes the voltage control unit 30 which generates first voltage information that can identify voltage applied to the first variable-focus lens 20A included in the first imaging unit 20 installed in a position where a subject can be photographed and whose focal length changes in accordance with an applied voltage, and generates second voltage information that can identify voltage applied to the second variable-focus lens 21A included in the second imaging unit 21 installed in the position where the subject can be photographed and whose focal length changes in accordance with an applied voltage, and the image judgment unit 40 which inputs images from the first imaging unit 20 and the second imaging unit 21, and selects one image taken at an in-focus position among input images, wherein the voltage control unit 30 generates information, as the first voltage information, that can identify each voltage in a time series of voltages whose values change with time, and generates information, as the second voltage information, that can identify that each of the voltages identified by the first voltage information is applied to the second variable-focus lens 21A after a predetermined period of delay.

    Abstract: 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.
