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.

A lighting unit has a plurality of light sources that emits excitation light having relative spectral distributions different from each other. An imaging unit simultaneously captures an image of fluorescent light emitted from the subject by the excitation light and an image of reflected light obtained by reflecting the excitation light by the subject, to generate a captured image. The arithmetic unit calculates a relative spectral distribution of the fluorescent light emitted from the subject by using the information about the relative spectral distribution of the reflected light for each of the plurality of light sources stored in the memory and the captured image for each of the plurality of light sources generated by the imaging unit.

Imaging device and image processing method

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.

Imaging apparatus and image processing method

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.
