摘要
基于衍射成像机理分析了景深的成因及其调控原理,针对数码成像中感光芯片的结构及其工作原理,提出了数码成像中景深调控的设想和方法,模拟实验表明这种方法是可行的,有助于改善数码成像的景深,还有利于改进快门、光圈以及感光度与白平衡等关键技术。
Based on diffraction imaging mechanism the causes and the principle of depth of field regulation is analyzed,aimed at structure and working principle of photosensitive chip of digital imaging,the idea and method of depth of field regulation for digital imaging is proposed,the simulations shows that this method is feasible and helpful to improve depth of field for digital imaging,and conducive to improve the key technology such as shutter,aperture and ISO and white balance.
