A method and hardware implementation of auto-focusing system for the camera

CHENG Yong Qiang,HUANG Ying Nan,XIE Ke Ming (College of Information Engineering, Taiyuan University of Technology, Taiyuan 030024 ,China)  
This paper introduces a method and hardware implementation of auto -focusing system based on digital image processing. Using a improved gray scale differential algorithm as evaluation function of focusing, different image quality on different lens positions are compared. According to the result of comparison the lens is drove to the position by single chip.
