Abstract

SE PRESENTA UN APARATO QUE ESTA PROVISTO CON EL PRIMER Y SEGUNDO CANAL PARA TRANSMITIR UNA SEÑAL DE VIDEO DE ENTRADA. EL PRIMER CANAL TIENE UNA MEMORIA LINEAL PARA PRODUCIR UNA DEMORA DE 1H SOBRE LOS DATOS Y UNA EXTENSION DE LA CORRIENTE DE VARIACION LINEAL USA LA MEMORIA LINEAL PARA PRODUCIR UN ENSANCHAMIENTO DE LA LINEA DE BARRIDO EN BASE A LOS DATOS CON LA DEMORA 1H. LOS DATOS SUJETOS A LA EXTENSION DE LA CORRIENTE DE VARIACION LINEAL SUFREN UNA CONVERSION D/A PARA EFECTUAR UNA SALIDA DEL PRIMER CANAL. POR OTRO LADO, EL SEGUNDO CANAL NO TIENE UNA MEMORIA LINEAL PARA UN RETARDO DE 1H, Y LA SEÑAL DE VIDEO SIN EL RETARDO ESTA SUJETA A LA EXTENSION DE LA CORRIENTE DE VARIACION LINEAL Y SUFRE UNA CONVERSION D/A PARA EFECTUAR UNA SALIDA DEL SEGUNDO CANAL. EN ESTA DISPOSICION, SE PERMITE INVERTIR UNA DISPOSICION DE LAS LINEAS SOBRANTES Y NIVELAR LAS LINEAS RESPECTIVAMENTE CONTENIDAS EN DOS TOMAS CONSECUTIVAS EN CADA CANAL DE TAL FORMA QUE EN UNA CIERTA TOMA, LAS LINEAS SOBRANTES DE LA SEÑAL DEVIDEO DE ENTRADA SE TRANSMITEN A TRAVES DEL PRIMER CANAL CON LINEAS NIVELADAS A TRAVES DEL SEGUNDO CANAL Y EN LA SIGUIENTE TOMA LAS LINEAS NIVELADAS SE TRANSMITEN A TRAVES DEL PRIMER CANAL CON LAS LINEAS SOBRANTES A TRAVES DEL SEGUNDO CANAL. DE ESTA FORMA, LAS INFLUENCIAS QUE SE DEBEN A LA DIFERENCIA DE LAS CARACTERISTICAS DEL CIRCUITO SE PROMEDIAN SOBRE LA IMAGEN REPRODUCIDA, Y SE EVITA QUE LA INFLUENCIA SE PERCIBA COMO DESNIVELACIONES DE COLOR O BRILLO.
