Claim 9:
10. The image processing system as claimed in claim 1, wherein the processor selects a thickest blood vessel image in the blood vessel segmentation image to determine a long axis of the optic disc image, selects the next thickest blood vessel image perpendicular to the long axis to determine a short axis of the optic disc image, the long axis of an optic cup image is parallel to the long axis of the optic disc image, a short axis of an optic cup image is parallel to the short axis of the optic disc image, the processor uses an ellipse fitting algorithm to crop the optic disc image according to the long axis of the optic disc image and the short axis of the optic disc image, and the processor uses the ellipse fitting algorithm to crop the optic cup image according to the long axis of the optic cup image and the short axis of the optic cup image.
