Auto-Focusing System Based on DSP

CAI Chang-jin~ 1,2 ,ZHU Ming~1 1.Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China; 2.Graduate School of the Chinese Academy of Sciences, Beijing 100039,China  
Due to the development of digital image process theory, auto-focusing system is changed from optic to digital image process now. An auto-focusing system including the functions of image sampling, preprocessing and real-time control is introduced. This system bases on the core digital signal processor chipset TMS320C6416. The hardware, principles and algorithms of this real-time digital image processing system are presented. The result indicates that the system has good properties of real time, stability and auto-focusing fast and exactly.
