AUTOFOCUS AREA DESIGN OF DIGITAL IMAGING SYSTEM

Li Qi,Xu Zhihai,Feng Huajun,Dai Shunlin,Bian Meijuan State Key Laboratory of Modern Optical Instrumentation,Zhejiang University,Hangzhou 310027  
With digital imaging technology developing to automation and intelligentization,autofocus became basic function of imaging system.The focus area design has important effect on focus success.This paper puts forward a focus area design method based on photography.Experimental results show that this method can improve autofocus capability of scence included multitude of depth of field.We can associate autofocus area design with experimence of traditional photography and make it an autofocus pattern configured in digital imaging system.
