Abstract

Un aparato de televisión comprende un exhibido r para una señal de videoque representa una imagen. La señal de video tiene un componente desincronización vertical que define campos de líneas horizontales quepueden tener un número diferente del número normal de líneas horizontalespor campo, bajo determinadas condiciones de operación. Unos contadores yenganches miden el número de líneas horizontales en campos sucesivos. Uncircuito de paneo genera una señal de restablecimiento vertical que estádesplazada en fase por un número seleccionado de líneas horizontales, conrespecto al componente de sincronización vertical de la señal de video,para paneo panear verticalmente la imagen en el exhibidor de video, unnúmero seleccionado de líneas horizontales. El número seleccionado delíneas horizontales es ajustado en respuesta a las longitudes medidas delos campos, para mantener la cantidad seleccionada de paneo verticalinclusive bajo las determinadas condiciones de operación.
