In color imaging, single sensor system with color filter array (CFA) is popular, especially with Bayer CFA. The improvement methods using white component have been studied. On the other hand, the performance of de-mosaicking is improved for Bayer CFA. We have studied the change of CFA color and the processing of the color plane reconstruction. In this report, we discussed LPF to abstract the average component. We choose 82% as the optimal cut-off frequency. The color differences are given by subtraction between each color and average component. As results of experiments, overall PSNR is improved, and, especially PSNR of luminance component are farther better than Bayer with conventional processing. |
