Claim 11:
12. The image processing method according to claim 10, further comprising:
setting a region as the background region when the difference of each pixel of the second invisible light image is less than a first threshold (where the first threshold is less than the predetermined threshold);
setting a pixel as a boundary pixel when the difference is at least the first threshold and not more than a second threshold (where the first threshold is less than the predetermined threshold, which is less than the second threshold);
setting a region as the subject region when the difference is greater than the second threshold;
reclassifying only the boundary pixel to the subject region or the background region using the second visible light image; and
correcting a contour of the subject region.
