In this paper, three patterns of R, two Gs, and B are presented and analyzed. The conventional Bayer CFA pattern has two Gs in diagonal location, and an R and a B are located in the rest part of CFA pair. In other words, red, green, and blue pixels are located as RGBG in clockwise. There are two alternatives of RGBG, which are RBGG and RGGB in clockwise. Four performance metrics (MSE, PSNR, S-CIELAB, and FSIM) are used to assess the superiority of three patterns. The experimental results show that RGBG in clockwise gives the best objective performance and reconstruct images were visually satisfied.
