Abstract: The apparatus calculates the intensity P of picture points (pels) in a transformed image (filtered, enlarged, reduced) from the equation … … where Ii are the intensities of each of m surrounding pels (reference window) in the original image and alpha i the associated weight factors.To allow flexible changes of the conversion, a loadable table (3) is provided which contains, for selected pels in the transformed image (e.g. along a scanning line), the associated weight factors of the pels in the reference window as well as the displacement by which the reference window has to be shifted to calculate the next transformed image pel.
