摘要: A specimen measuring device includes: a light source device that irradiates a specimen surface of a specimen with illumination light from multiple illumination units at a plurality of illumination angles; a spectral camera device that is arranged above the specimen surface, spectrally separates reflected light from the specimen surface, and acquires 2D spectral information through a single image capturing operation; and a calculating unit that calculates deflection angle spectral information of the specimen surface used to measure a measurement value of a certain evaluation item of the specimen using a change in an optical geometrical condition of an illumination direction and an image capturing direction between pixels in an X axis direction and a Y axis direction of the spectral information.

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.
