The three CCD imaging method provides high quality pictures because of sufficient color sampling points. However, it requires a color separation prism. On the other hand, single chip CCD imaging has an advantage to reduce camera size but insufficient color sampling points. With the aim of realizing a small size and high quality camera, we have been studying imaging method for NTSC using single chip HDTV CCD. The arrangement of a color filter array is a key issue to improve color image quality. In this paper, we propose a new color filter array, and we examine driving CCD with this filter array and color separation method for both HDTV and NTSC. The proposed filter array has quincunx sampling structure for difference color signal, resulting in improved color resolution.
