This invention relates to a white light and narrow-band dual-mode capsule endoscope high quality image sensing color filter array, it is an image sensing mechanism consists of a plurality of color array of filter units, and each color array of filter unit includes a red pixel filter, a green pixel filter equipped on one side of the red pixel filter, a blue pixel filter equipped below the green pixel filter, and a transparent pixel filter equipped beside the blue pixel filter and below the red pixel filter as such, each of the filter can be arrange in an optimal manner moreover, narrow-band auxiliary information is added when decoding mosaic so as to enhance the maximum signal to noise ratio, color difference and structural similarity of the image for achieving the efficacy of enhancing the white light and narrow-band image quality.一種白光及窄波段雙模式膠囊內視鏡高品質影像感測彩色濾波陣列,其係由多數彩色陣列濾波單元所構成之影像感測機構,而各彩色陣列濾波單元係包括有一紅光像素濾波器、一設於紅光像素濾波器一側之綠光像素濾波器、一設於綠光像素濾波器下方之藍光像素濾波器、及一設於藍光像素濾波器一側且位於紅光像素濾波器下方之透明像素濾波器。藉此,可使各濾波器為最佳化方式進行排列,並於解碼賽克時加入窄波段輔助資訊,進而提昇影像之最大訊號雜訊比、色差及結構相似度,而達到同時提高白光與窄波段影像品質之功效。1...影像感測機構11...彩色陣列濾波單元111...紅光像素濾波器112...綠光像素濾波器113...藍光像素濾波器114...透明像素濾波器
