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. We have proposed new imaging system with pastel color CFA and the color plane reconstruction method which abstracts the white like component from RAW images. Also, color plane reconstruction method using the color difference and the method inter correlation between white like component and pastel colors were discussed for pastel color CFA. In this report, we discuss color plane reconstruction method adding the high component of white like component to all pastel colors. We evaluate the reconstruction performance of RGB images and the overall performance include video coding. As results of experiments, it is recognized that the PSNR of luminance / chrominance signal is improved by new method. |
