Abstract
In this paper, we develop an auto-focus algorithm using a new sharpness function. Different from other sharpness functions used for auto-focusing in the past, the new defined sharpness function is more robust to noise, jitter of the camera. In order to test the algorithm, a modified hill climbing algorithm is used in the experiments to find the focused lens position and the experimental results show that the new auto-focus algorithm based on the new sharpness function has better performance.
