A method of and apparatus for convolution that provides both scaling and elimination of flicker when displaying computer generated or computer processed information on an interlaced, television monitor. One preferred embodiment includes a bilinear interpolation for scaling combined with a modified three line convolution for flicker reduction. In one preferred embodiment, 8 lines of a source computer image are scaled to 7 lines of a television image for display. The weighted contribution of each input line varies according to which combination of lines contribute to each output line, and the mathematically optimal weighting factors are modified for easier implementation in hardware.
