| Title: | An efficient combined demosaicing and zooming algorithm for digital camera | Authors: | Chung, KH Chan, YH Fu, CH Chan, YL |
Issue Date: | 2007 | Source: | ICIP 2007: 2007 IEEE International Conference on Image Processing : proceedings : September 16-19, 2007, San Antonio, Texas, U.S.A., p. IV197-IV200 | Abstract: | Color demosaicing and digital zooming are common processes in digital cameras and they often employ similar interpolation concepts based on the information extracted from the raw sensor data. Realizing them independently is not efficient as separate extraction processes are required. It may also cause inconsistent utilization of the raw sensor data in different stages. This paper presents a low-complexity combined algorithm which directly extracts edge information from raw sensor data and exploits it consistently and efficiently in both demosaicing and zooming. The proposed algorithm can produce zoomed full-color images and zoomed CFA images with outstanding performance as compared with conventional approaches. | Keywords: | Interpolation Color filter array Cameras |
