Title
(EN) PICTURE SIGNAL PROCESSOR
(FR) PROCESSEUR DE SIGNAUX D'IMAGE
Abstract
(EN)
Interlace scan PALplus signals are fed to a 133-line delay (32) which is a delay element of 133 lines. The output of the delay element is fed to field memories (23 and 25). The memory (23) is a first memory for one-field delay and the output of the memory (23) is fed to a field memory (24) which is provided as a second memory. The memory (24) performs shuffling on a field A and, at the same time, data in the memory (24) is read at a double speed so that the same field A may appear continuously four times. The field memory (25) which is provided as a third memory is controlled so that readout from the memory (25) may be started prescribed time after write and performs shuffling on a field B. At the same time, readout from the memory (25) is performed at a double speed so that the same field B may appear continuously four times. The picture signals read out from the memories (24 and 25) are fed to a vertical filter/median processing section (26) which is provided as a scanning line interpolating means.

Des signaux PALplus à balayage entrelacé sont injectés dans une unité à retard (32) à 133 lignes, qui constitue un élément à retard de 133 lignes. Le produit de l'élément de retard est appliqué à des mémoire de champ (23 et 25). La mémoire 23 est une première mémoire pour retard d'un champ et le produit de la mémoire (23) est appliqué à une mémoire de champ (24) qui constitue une deuxième mémoire. La mémoire (24) accomplit un brassage sur un champ A et, simultanément, les données dans la mémoire (24) sont lues à une vitessse double, de sorte que le même champ A puisse apparaître de manière continue quatre fois. La mémoire de champ (25) qui est prévue comme troisième mémoire est commandée de telle sorte que l'affichage en sortie de cette mémoire (25) puisse commencer au moment prescrit après l'écriture et effectue un brassage sur un champ B. Simultanément l'affichage en sortie de la mémoire (25) s'effectue à une vitesse double, de sorte que le même champ B puisse apparaître de manière continue quatre fois. Les signaux d'image lus à partir des mémoires (24 et 25) sont communiqués à une unité de traitement (26) médian à filtre vertical, qui sert de dispositif d'interpolation de ligne de balayage.
