Abstract (in Japanese) (See Japanese page) 
(in English) In color imaging, single sensor system with color filter array (CFA) is popular, especially with Bayer CFA. The resolution and the sensitivity of single sensor are poor than three sensor system. Therefore, the improvement method using white component have been studied. On the other hand, the performance of de-mosaicking is improved by using correlation of color planes. However, it is mostly for Bayer CFA. We have reported the CFA that has more green pixels to improve luminance resolution with high level de-mosaicking. In this report, we still try to change both CFA and processing. This time, we do not change the array, but color of filter is changed to pastel color. About the color plane reconstruction, the method that abstract the average component of RAW image is discussed. By the experiment of non-adaptive processing, it is recognized that the PSNRs especially about average component are improved.
