右图是尼康公司官方提供的D800和D800E低通滤镜(低通滤波器)工作原理图,上为D800,下为D800E。D800的低通滤镜工作原理如其他普通的数码相机一样:光线穿过第一片低通滤镜后一分为二,然后穿过红外滤镜;当穿过第二片低通滤镜时再被一分为二,从而变成四个分量到达影像传感器上。光线最终一分为四的间隔比影像传感器的像素间隔小很多,避免了“撞网”现象,从而可以减少摩尔纹和伪色出现,但是这种方案存在降低分辨率的可能。D800E的低通滤镜工作原理则是一种崭新的方案:光线穿过第一片低通滤镜
The right is the Nikon official D800 and D800E low-pass filter (low-pass filter) working principle diagram, on the D800, under the D800E. D800 low-pass filter works like other ordinary digital cameras: the light through the first piece of low-pass filter is divided into two, and then through the infrared filter; when passing through the second piece of low-pass filter And then split into two, which becomes four components reach the image sensor. The light is finally divided into four intervals that are much smaller than the pixel spacing of the image sensor, avoiding “bumping into the net” and thus reducing the appearance of moiré and false colors, but this solution has the potential of lowering the resolution. D800E low-pass filter works is a new program: light through the first low-pass filter
