Abstract
Dispositivo, en particular adaptador VGA (18; 118), para el control simultáneo de varios dispositivos de representación (18; 18), donde el dispositivo convierte los datos de la imagen en señales de representación (AS1, AS2; AS10, AS20) y las transmite al dispositivo de representación (20, 22; 120, 122) con el fin de generar una imagen completa o una ventana (W1, W2) a partir de la imagen completa o también a partir de una parte de una superficie de imagen virtual a representar completa sobre los dispositivos de representación (20, 22; 120, 122), y donde el dispositivo comprende: - una memoria de vídeo (38; 138), que memoriza datos de imagen de una imagen completa, - un circuito de conversión (24; 124), que está conectado con la memoria de vídeo (38; 138) y a partir de los datos de imagen leídos desde la memoria de vídeo (38; 138) de una manera secuencial o también de una manera opcional genera señales de representación (AS1, AS2; AS10, AS20)que activan los dispositivos de representación (20, 22; 120, 122) y que tienen un valor cromático o un valor estándar, - un dispositivo de registro (32; 132), que está conectado con el circuito de conversión (24; 124) y que memoriza datos de la ventana, que identifican cada ventana de la imagen completa que debe ser representada sobre uno de los dispositivos de representación (20, 22; 120, 122), - el dispositivo de registro (32; 132) tiene un registro (33; 133, 133¿, 133¿) con varias áreas de registro, que están asociadas en cada caso a uno de los n dispositivos de representación (20, 22; 120, 122), - el dispositivo de registro (132) contiene un tercer registro (133¿) para cada dispositivo de representación (120, 122) a activar para la memorización de un factor de ampliación (SF), que es una medida para la magnitud con la que una ventana (W1, W2) debe ser representada sobre el dispositivo de representación (122), donde el dispositivo de conversión (24; 124) genera señales de representación (AS1, AS2; AS10, AS20) con valor cromático en función de los datos de la ventana del dispositivo de registro (32; 132) para aquellos datos de la imagen que están asociados a la ventana (W1, W2) de la imagen completa que debe representarse en cada caso, y donde el circuito de conversión (24; 124) genera señales de representación (AS1, AS2; AS10, AS20) con valor estándar para todos los otros datos de la imagen, que no están asociados a la ventana (W1, W2) de la imagen completa que debe representarse en cada caso.
