Abstract

This research proposes a new method of optical system optimization for both optics and image processing, as a route to achieving best performance. Traditionally, optics is optimized independently without taking account of image processing. In this research, optimization work will be further studied with the concept of digital image processing (DIP), point spread function (PSF) and modulation transfer function (MTF), in order to reduce the size of miniature zoom lenses without sacrificing image quality. Experimental results show that optimization taking account of image processing yields much better performance than optimization which ignores it. From another point of view, it is concluded that equivalent performance may be achieved in the following two cases: one is having a poor lens with optimization work combined with image processing; the other is good optics without optimization work combined with image processing.
