Abstract
The invention relates to interpolation of an image information value for a pixel of an interline. The method comprises selecting, from a number of image directions, to each of which a direction quality value is assigned, a direction of interpolation by comparing these direction quality values. The image information value being interpolated is determined in dependence on image information values assigned to pixels lying adjacent to the pixel being interpolated in the direction of interpolation. To ascertain a direction quality value for an image direction a pixel group having at least two pixels is selected; a single direction quality value for each pixel of the pixel group is determined, the single direction quality value being dependent on image information values assigned to image regions lying adjacent to the particular pixel of the group in the image direction; and a direction quality value is created as a function of the single direction quality values of the pixel group.
