Abstract
Method and apparatus for converting an input scanning sequence into an output scanning sequence, where scan values of an input scanning sequence occurring with an input scanning frequency are converted into an output scanning sequence whose scan values occur with an output scanning frequency. To process scanning sequences with alternating scanning frequencies with limited computing and storage capacities, a single one-stage digital filter is provided for processing the input scanning sequence using a limited number of filter coefficients, further filter coefficients supplied thereto by calculation from existing filter coefficients.
