In recent years, due to higher resolution display, high definition image research has been actively carried out, the method using fractal technique has been studied in particular. In the super-resolution processing fractal as an existing technology, a method to shorten the time by using initial image enlarged by interpolation was proposed. A method to increase the number of domain blocks by using rotating image was also proposed. Further, a method to improve the processing speed by finding domain blocks from the position around the range block was proposed. These methods can keep the continuity of edges, but may not be able to reproduce the gradation with a graduated change. In this paper, we propose a method dividing the image into subregion slightly larger than the domain block, and executing different enlargement process to different area. In the edge region, fractal brightness variance is used, and in the gradation region the interpolation formula is used. It was confirmed that the proposal method has the advantages of the method using fractal and the advantages of the method using interpolation. |
