Abstract

The invention relates to a method and a device to increase the resolution of an image by interpolating along edges of the image. Edges are detected and their direction is calculated ( 10 ). The interpolation ( 12 ) of new pixels is carried out along the direction of the edges. According to the invention, a pre-filter ( 8 ) is used with a high-pass filtering in the direction in which new pixels are interpolated, and a low-pass filtering in another direction.
