ABSTRACT:
An improved image scaling filter for a video display where a coefficient value for the closest input lines to a given output line that are less than two line lengths from the given output line are determined by cubic interpolation using the line distances. The input lines are multiplied by the coefficient for that line and the multiplied closest input line values are summed to determine the output line value.
