摘要

彩色滤波阵列(CFA)用于CCD和cmos传感器获取彩色图像,决定了图像的最终质量。本文讨论了对CFA同时提供高灵敏度和高分辨率的要求问题。通过对CFA关键参数的优化,得到了新的滤波器。计算机仿真结果表明,该算法在客观图像质量和主观图像质量两方面都优于已知算法。

A new color filter array with high light sensitivity and high resolution properties
Color filter array (CFA) used in CCD and CMOS-sensor to acquire color images determinate the end quality of the image. In this paper the question of the requirements for the CFA to provide both high sensitivity and resolution is discussed. By optimizing the key parameters of the CFA new filters are obtained. The computer simulation proved that proposed CFA outperform known CFA by meanings of objective and subjective image quality.
