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.
This research proposes a newly developed method to high zoom lens for mobile phone use, which the
overall length is restricted in mobile phone size acceptable. Generally speaking, the optical design with liquid
lens might be more complicated in optimization than traditional optics; not only because aspherical coefficient
in liquid lens element is difficult to be defined and measured, but also because efficient optics layout needs
more efforts to study in the near future. The paper mainly utilizes liquid lens in order to short total length; two
liquid lens elements must be included. Besides consider total length, Lateral aberration also is very important.
Lateral aberration will play a significant role in the Modulation Transfer function (MTF), so, the optical design
will be able to arise very big, and that the many kinds of chromatics aberration with two groups of liquid lens. Using
Digital Signal Processing technology principal factor why this also is.
