Method and apparatus for interline interpolation

A method for interpolation of a video information value for a pixel (15) is a two-row (y), comprising the steps of: - selecting an interpolation (dx0) from a number of image devices (dx), which in each case a directional quality value (qd) is assigned, based on a comparison of the direction of quality values, - determining the to be interpolated image information value (S (x, y)) in accordance with image information values, the pixels are assigned, which are in the interpolation direction (dx) adjacent to the to be interpolated pixel (x, y), and having the following method steps for determining a direction quality value (qd) for an image direction: - selecting a pixel group consisting of at least two image points, - determining in each case a single-direction quality value (q) for each pixel of the pixel group, wherein the single-direction quality value (q) is dependent on image information values ​​that are associated with image regions that lie in the image direction (dx) adjacent to the respective pixel of the group, - generating the direction quality value as a function of the single direction quality values ​​(q) of the pixel group.
