Improvement of Pixel Interpolation Accuracy Based on Edge Direction for High Resolution Imaging

In this paper, We propose a new method of pixel interpolation using edge direction to high resolution imaging. In the conventional method, the pixel is interpolated by dividing the processing of the edge and the flat portion. However, the interpolation method in the edge portion was not sufficient. Therefore, when interpolating the pixel, we changing the appropriate direction of the edge to reference the scope of the surrounding pixels. In addition, by eliminating the problems caused by changing the reference range, we will improve the accuracy. We confirm that our method’s interpolated pixels improver than conventional method’s interpolated pixels by experiment
