Abstract: An image acquisition system according to the present invention includes: a display device including a display surface on which a subject can be mounted; and the image acquisition device that is disposed face-down at a position above the display device in a manner spaced apart from the display surface, the display device being disposed with the display surface face-up, and that acquires images of the display surface and the subject placed on the display surface, wherein the image acquisition device includes a transmission unit that transmits the acquired images, and the display device includes: a reception unit that receives the transmitted images; a relative-position calculation unit that calculates the relative position between the display device and the image acquisition device on the basis of the received image; and a display control unit that controls content displayed on the display surface on the basis of the calculated relative position.

Abstract: Provided is an image acquisition system according to the present invention includes: a display device that has a display surface on which an image is displayed; a dome-shaped reflective member that is disposed so as to cover at least a part of the display surface of the display device, that includes a reflective surface reflecting light from the display surface, on an inner surface thereof, and has a through-hole that passes between an interior and an exterior; and a photographing device that photographs light radiated from the display surface via the through-hole, while a subject is disposed at a position between the reflective member and the display surface.

Abstract: An image capturing device includes: an illuminator configured to generate illumination light having wavelength bands and an illumination characteristic; an imager configured to generate an image signal by capturing light from a subject; and a processor configured to: control the illumination characteristic; set a piece of statistical data used for estimating a spectral characteristic of the subject included in the image signal; estimate the spectral characteristic of the subject included in the image signal based on the set piece of statistical data; define an illumination characteristic of illumination light in accordance with the estimated spectral characteristic of the subject; and determine whether or not the set piece of statistical data is an adequate piece of statistical data based on whether or not an image signal generated by the imager under the illumination light having the defined illumination characteristic satisfies a criterion for achromatic color.

Abstract: A subject identification device includes: an illuminator configured to generate illumination light including components at a plurality of wavelength bands, each of the components having a characteristic in accordance with a respective one of settings; an imager configured to generate an image signal by capturing light from a subject under the illumination light having the illumination characteristic; and a processor including hardware. The processor is configured to: define an illumination characteristic of the illumination light; analyze the image signal to acquire spectral information of the subject; and cross check the spectral information of the subject with subject identification information in order to identify the subject. When the subject is not identified, the processor is configured to define another illumination characteristic that causes spectral information of potentials for the subject to be identified, and subsequently each of the imager and the processor performs a process.

Abstract: An image capturing device includes: an illuminator configured to generate illumination light composed of components at a plurality of wavelength bands, each of the components having a characteristic in accordance with a corresponding one of settings; an imager configured to generate an image signal by capturing light from a subject; and a processor. The processor is configured to: set an acquisition condition for acquiring spectral information of the subject, the acquisition condition including a condition related to an operation of each of the illuminator and the imager; analyze the image signal generated by the imager based on the acquisition condition in order to acquire the spectral information of the subject; determine whether or not the acquired spectral information satisfies an end condition for ending acquisition of the spectral information; and change the acquisition condition when the processor determines that the end condition is not satisfied.
