Claim 2:
3. The inspection apparatus according to claim 2, wherein the processor is configured to execute the program instructions to:
for each of the partial areas, in the extraction of the narrow-angle partial area image, use the image of the partial area shot with the first imaging unit as a reference image, extract a plurality of feature points from the reference image, use an image shot with the second imaging unit as an original image, detect a corresponding point that corresponds to the feature point from the original image, calculate a projective transformation parameter for geometrically transforming the original image so that the corresponding point and the feature point overlap, position the original image using the calculated projective transformation parameter, and extract an area corresponding to the reference image as the narrow-angle partial area image from the original image after positioning.
