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.

Industrial camera

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.
