    Abstract: An industrial camera includes an imaging unit generating a captured image with a number of pixels larger than a number of pixels of the inspection target image, an image generation unit downscaling a first captured image corresponding to an output region which is a region of a field of view range (FOV) of the imaging unit in whole or part at a first scaling magnification to generate an inspection target image with a first number of pixels smaller than a number of pixels of the first captured image, an interface unit receiving a first zoom instruction to change the output region to a relatively small region, and a calculation unit calculating a second scaling magnification. The image generation unit generates an inspection target image with the first number of pixels by downscaling the second captured image at the second scaling magnification.

    Abstract: An industrial camera includes an electric zoom optical system, an imaging unit generating a captured image with a number of pixels larger than a number of pixels of an inspection target image, an image generation unit executing downscaling a captured image corresponding to an output region of the imaging unit, an interface unit receiving designation of a zoom magnification, and a calculation unit calculating an optical magnification of optical zooming and a magnification of the downscaling based on the zoom magnification. When the zoom magnification is smaller than or equal to a predetermined magnification, an inspection target image is generated by downscaling a captured image at a scaling magnification calculated based on the zoom magnification. When the zoom magnification is larger than the predetermined magnification, the zoom optical system is driven at the optical magnification calculated based on the zoom magnification to generate an inspection target image.

    Abstract: There is provided an attachment for an illumination device which can change a ring-shaped illumination device to a dome-shaped illumination device. An attachment for dome illumination includes: a dome member made of a material that transmits and diffuses light emitted from a light emitting opening section of the ring-shaped illumination device inwardly; a plate member connected to the dome member, and connected to a main case so as not to form a gap when the attachment for dome illumination is fitted to the ring-shaped illumination device; and a dome cover which holds the dome member and the plate member so as to shield the space formed by the dome member, the plate member, and the light emitting opening section from light when the attachment for dome illumination is fitted to the ring-shaped illumination device.

    Abstract: An image processing device includes an imaging unit generating an inspection target image, a storage unit storing a reference image obtained by capturing an inspection object in advance, and a calculation unit specifying a positional relationship between an inspection object included in the inspection target image generated during operation and the inspection object included in the reference image, and calculates a generation condition of the inspection target image during operation such that the inspection object included in the inspection target image generated during operation and the inspection object included in the reference image are at substantially the same position. The generation condition includes positional information of an output region in which the inspection object is able to be output at substantially the same position as the reference image. The imaging unit generates an inspection target image corresponding to the output region of the positional information during operation.
