1. An industrial camera that generates an inspection target image obtained by capturing an inspection object, comprising:
an imaging unit that captures the inspection object to be able to generate a captured image with a number of pixels larger than a number of pixels of the inspection target image;
an image generation unit that downscales a first captured image corresponding to an output region which is a region of a field of view range 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 that receives a first zoom instruction to change the output region to a relatively small region; and
a calculation unit that calculates a second scaling magnification necessary for setting a second captured image corresponding to an output region after the change in the field of view range of the imaging unit to the first number of pixels,
wherein 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 calculated by the calculation unit.
