Abstract
Recently, CFA sensors including the W channel have been developed. Since the W channel receives luminance information, the W channel has a wider spectrum band than that of the R, G, and B channels. Therefore, the W channel can get higher SNR than that of the R, G, and B channels. There are many color interpolation methods for the Bayer CFA, but less for the RGBW CFA. In this paper, we propose a new color interpolation method for white-dominant RGBW CFA. The proposed method is edge-adaptive. Its method reconstruct the W channel first which has a high sampling rate. Next, the R, G, and B channels are reconstructed by using the color difference domains with the W channel. Experimental results show that the PSNR and visual confirmation are higher than the conventional method.
