Abstract

A wide-angle endoscope lens is configured to capture a large viewing angle area of a non-planar object to generate an image, wherein the wide-angle endoscope lens has a center region and a corner region. The center region has a corresponding central object distance range. The corner region surrounds and adjoins the center region, and has a corresponding corner object distance range, wherein the central object distance range is different from the corner object distance range, a first resolution of the image of the non-planar object captured at a central shortest object distance in the central object distance range and a second resolution of the image of the non-planar object captured at a central farthest object distance in the central object distance range are substantially the same, and a third resolution of the image of the non-planar object captured at a corner shortest object distance in the corner object distance range and a fourth resolution of the image of the non-planar object captured at a corner farthest object distance in the corner object distance range are substantially the same.
