    摘要: An imaging device includes a filter unit including filter areas having different wavelength selectivities; a light receiving element array configured to receive light transmitted through the filter unit; a storage unit configured to store, for each filter area, positional information indicating a position at which light transmitted is received on the light receiving element array; an area detector configured to detect, based on the positional information, an image area corresponding to the light transmitted from an image output by the light receiving element array when light from an object enters the filter unit; and a color detector configured to detect a color of the object based on an output value of the image area. The positional information indicates a position on the light receiving element array identified by using a spectral-response-coincidence-degree indicating a degree of coincidence between a spectral responsivity of each pixel and a desired wavelength selectivity.

    摘要: An imaging device includes a filter, an imaging element, a lens, a spectral image generator, and an exposure adjuster. The filter includes a plurality of filter areas having different spectral transmission characteristics. The imaging element receives light transmitted through the filter and outputs image information. The lens array includes a plurality of lenses arranged approximately parallel to a light receiving surface of the imaging element and is arranged between the filter and the imaging element. The spectral image generator generates a plurality of spectral images respectively corresponding to the plurality of filter areas on the basis of the image information output by the imaging element. The exposure adjuster adjusts an exposure time of the imaging element on the basis of luminance values of the spectral images.
