In this paper, we propose a method of pixel interpolation using adaptive processing window for edge features. To date, we consider that a method of pixel interpolation to divide the processing of the edges and flat regions. However, type of processing window that is provided is not sufficient. Thereby the combination of the processing window and the edge limit. Therefore, our method select to apply a processing window based on the direction and intensity of the various edge. We confirm that our method’s interpolated pixels improver than conventional method’s interpolated pixels by experiment.
