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.
