Abstract: An imaging lighting device of an appearance inspection device images a product T. A controller of the appearance inspection device causes an imaging control unit to obtain an image, a preprocessing unit to position the product and remove background of the product, a color space processing unit to perform color space processing for emphasizing a defect such as a flaw and a dent of the product and to create a color space processing image, and an assessment unit to make an quality assessment of the product using a learned model obtained through machine learning of quality assessment of the product using the color space processing image.

Abstract: An aim is to provide an imaging apparatus that can reduce the size without being constrained by the size of a mechanism that drives the apparatus, and can accurately move a field of view over a wide range in a narrow space. The apparatus includes an image-wise light receiving means, a spherical housing that holds therein the image-wise light receiving means, a base that supports the spherical housing and enables the spherical housing to freely move along a surface thereof, a drive wire having an end fixed to the spherical housing, and a drive section to which the other end of the drive wire is fixed to drive the free movement of the spherical housing via the drive wire.

Abstract: Disclosed is a simple lighting device for photographing, which makes it possible to take an artistic picture of a human, which is an object to be photographed, enhancing his or her facial expressions, without the need of troublesome light source adjustment. The lighting device comprises a reflecting plate (2) which has a concave shaped surface with respect to the object to be photographed and which has a transmission area (22) which permits light to pass therethrough, and a light emitter (1) which is provided on the convex surface side of the reflecting plate (2) and which emits light toward the transmission area (22). The light emitted from the light emitter (1) and transmitted through the transmission area (22) is irradiated onto the object to be photographed and is reflected by the reflecting plate (2) toward the object to be photographed.
