An apparatus simultaneously flicker filters and vertically contracts a plurality of original lines to form compensated lines. The device uses a coefficient calculator and a line processor, both controlled by a controller. The coefficient calculator provides compensation coefficients to the line processor. The line processor forms weighted sums of the original lines, with the weightings determined by the compensation coefficients. The compensation coefficients are chosen to simultaneously implement flicker filtering and vertical contraction. Thus, the weighted sums are the compensated lines. |
