Abstract
This paper is about new method of image resolution enhancement that is a new method of Super-resolution. Super-Resolution is the word given to the techniques that generate high resolution image from a set of low resolution images. The paper describes about a new Super-resolution technique based on random motion of image sensor. However the term Super-resolution is usually used to describe methods that differ on mathematical aspects and do not involve any hardware change. But this time the change in hardware is simple and does not involve much complexity. So it will serve as an inexpensive technique to acquire high resolution images. The required low resolution images that contains sub-pixel information for the generation of high resolution image is acquired by the image sensor which is free to move on its horizontal and vertical axes but only in sub-pixel range. This motion of the image sensor is the result of vibration of piezoelectric material on the edges of the image sensor. The generation of high resolution image from the acquired set of low resolution images is based on Maximum-a-posteriori method of Super-resolution.
