Abstract: A multi-optic vision device includes a dark-vision lighting apparatus illuminating a defect on a subject and leaving regions that surround the defect dark. A bright-vision lighting apparatus illuminates the subject and the regions that surround the defect and leaving the defect dark. A differential-vision lighting apparatus illuminates the subject so as to stereoscopically show the defect on the subject. An area scan camera continuously imaging the subject as the dark-vision lighting apparatus, the bright-vision lighting apparatus, and the differential-vision lighting apparatus simultaneously and respectively provide light. A controller processes the image to respectively obtain a dark-vision image, a bright-vision image, and a differential-vision image of the subject.
