Abstract
A format conversion is necessary if video picture sequences are to be displayed on computer screens. The conversion is carried out with the aid of a direction dependent interpolation within the moving objects. For this purpose interpolation lines which are rotated with respect to one another are projected through the pixel to be generated and their intersection with adjacently situated lines of pixels in the first pixel raster is determined. The changes in brightness value between the respective intersections of the interpolation lines with the adjacent lines, these intersections being allocated to the individual interpolation directions, are then determined. That interpolation line is selected whose change in brightness value is a minimum compared with the changes in brightness value of adjacently situated interpolation line. The brightness value of the pixel to be generated in then generated by interpolation in the direction of the interpolation line thus determined.
