An apparatus simultaneously flicker filters and vertically contracts a plurality of original lines to form compensated lines. The device uses a coefficient calculator (704) and a line processor (700), both controlled by a controller (706). The coefficient calculator provides compensation coefficients to the line processor. The line processor (700) forms weighted sums of the original lines, with the weightings determined by compensation coefficients. The compensation coefficients are chosen to sumultaneously implement flicker filtering and vertical contraction. Thus, the weighted sums are the compensated lines.
Selon cette invention, un appareil filtre le papillotement et, simultanément, contracte verticalement plusieurs lignes originales pour former des lignes compensées. Le dispositif utilise un calculateur de coefficient (704) et un processeur de lignes (700), les deux étant commandés par un contrôleur. Le calculateur de coefficients fournit au processeur de lignes des coefficients de compensation. Le processeur de lignes (700) produit des sommes pondérées des lignes originales, les pondérations étant déterminées par les coefficients de compensation. Les coefficients de compensation sont choisis pour effectuer simultanément le filtrage du papillotement et la contraction verticale. Les sommes pondérées constituent les lignes compensées.
