Abstract: An appearance inspection apparatus includes a lighting unit, an imaging unit, a memory, an operating unit, a detecting unit, and a determination unit. The lighting unit has a plurality of light sources emitting single-wavelength light with relative spectral distributions different from one another, and substantially simultaneously irradiates a photographic subject with illumination light. The imaging unit captures light discharged by the photographic subject. The memory stores information about sensitivity characteristics of the imaging unit for each color. The operating unit separates an image into a first, a second, and a third image, for each component of the single-wavelength light, using the information. The detecting detects information about a specific area of the photographic subject using the first and the second image. The determination unit extracts an amount of image characteristics corresponding to a characteristic part present in the specific area using the first and the third image.

Abstract: An imaging system includes an imaging apparatus that repeatedly acquires a compressed image in which information regarding light of four or more wavelength bands from a target is compressed, and a processing apparatus. The processing apparatus extracts a partial region including a region of the target from the compressed image so as to compensate for a relative motion between the target and the imaging apparatus, and generates spectral images corresponding to wavelength bands, based on data of the partial region of the compressed image.

Abstract: A collation device includes: a storage that stores a search target image showing a search target; an acquisition unit that acquires a captured image generated by an imaging device; and a controller that determines whether the search target is included in the captured image. The controller searches out a collation area in the captured image, the collation area including a subject similar to at least a part of the search target, and selects, depending on the collation area, at least one of a whole of the search target image and a part of the search target image, and collates the selected at least one with the captured image so as to determine whether the search target is included in the captured image.

Abstract: A lighting unit includes a plurality of light sources that respectively emit plural rays of illumination light. An imaging unit that simultaneously images plural rays of reflected light obtained by the plural rays of illumination light being reflected by a subject so as to obtain information about a plurality of colors, and generates a captured image including the information about the plurality of colors. A memory stores sensitivity information items that correspond to the plurality of light sources respectively. An arithmetic unit performs an arithmetic operation to generate a plurality of separated images from the captured image by using the sensitivity information items. The plurality of separated images correspond to the plurality of light sources respectively, and each of the plurality of separated images only includes information about a corresponding one of the plural rays of reflected light.
