Abstract
The present invention relates to interpolating a pixel in an image that includes a number of pixels arrayed in matrix-like fashion, to each of which a video information value is assigned, in which method a gradient for the video information value is determined at, at least, a first and a second pixel adjacent to the pixel to be interpolated and, in the formation of the interpolated video information value, a greater weight is accorded to the video information value of the adjacent pixels whose associated gradient is smaller.
