Visual artifacts, normally characteristic of interpolated images, are minimized by a method of adaptive interpolation in which pixel values of a current line to be interpolated are determined from respective values of vertically adjacent pixels of adjacent lines in a current field. The values are adaplively weighted according to one or more gradients of respectively located pixel values of one or more temporally adjacent fields thereby providing an interpolated image having improved sharpness, no temporal lag, and no switching artifacts.
