    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.

    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 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.
