	Design of video auto focusing based on image processing (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China Meng B.; Zhu M.; Cai C.-J. 收藏 \| 浏览/下载：19/0 \| 提交时间：2013/03/25 In order to realize the auto focusing technique based on digital image processing a video image processing system is designed by using high-performance digital signal processor TMS320VC5509 as the core field programmable gate array FPGA for preprocessing of image. At the same time it is proposed to use vector norm sum of image gray gradient as evaluation functions of digital image. It has the characteristics of good unbiasedness powerful unimodality etc. and can be applied to evaluation of defocusing. The hardware composition of the theory behind the auto focusing system and the application of the evaluation function are discussed in details.
