摘    要:本文从摄影艺术的角度,提出一种对焦区域选择策略.经实验证明,这种区域选择策略可以提高多景深场景的自动对焦的有效性,并可作为一种自动对焦模式预置于数字成象系统中,从而把传统摄影技术中的各种经验知识结合到对焦区域设计的策略中,使以对焦为关键技术的数字相机、数字摄象机从原理上被人们所接受.

关 键 词:自动对焦  数字成象系统  对焦区域设计

Abstract: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.
Keywords:Autofocus  Digital imaging system  Focus area design
