摘要

介绍了基于Bayer滤波获取彩色图像的方法。根据CCD离散采样的工作特点

构建了采用Bayer滤波的彩色面阵CCD的调制传递函数(MTF)。通过数值计算和实验对基于Bayer滤波的彩色面阵CCD和单色面阵CCD的MTF值进行了对比分析。结果表明

基于Bayer滤波的彩色面阵CCD的MTF值显著低于单色面阵CCD的MTF值。当像元边长与对应中心距相等时

基于Bayer滤波的彩色面阵CCD在Nyquist频率处的MTF为0.067 6

单色面阵CCD在Nyquist频率处的MTF值为0.405 3;分辨率板成像实验表明

相同成像条件下

前者的分辨率比后者的分辨率降低约40%

基本符合MTF对比分析结论。

Abstract

A method based on Bayer filtering to obtain color images was introduced

then the Modulation Transfer Function (MTF) of a color area Charge Coupled Device (CCD) which uses the Bayer filtering to obtain color images was established based on the discrete sampling characteristic of CCD. The MTF values for the color area CCD using Bayer filtering were compared with those of a monochrome area CCD. Obtained results indicate that the MTF value for color area CCD using Bayer filtering is notably lower than that for the monochrome area CCD. When the side length of a pixel is equal to the corresponding center distance

the MTF value at Nyquist frequency is 0.067 6 for the color area CCD using Bayer filtering while that is 0.405 3 for the monochrome area CCD. Moreover

in an imaging experiment using a resolution card

the resolution of the former is lower about 40% than that of the latter in the same imaging condition. These results are coincident with comparative analysis results of MTFs in general.
