Abstract

EN UN APARATO DE REPRESENTACION, EN COLOR, DE PLANOS SECUENCIALES, UN DETECTOR DE VALORES MINIMOS (5) DETECTA UN VALOR MINIMO ENTRE LAS SEÑALES DIGITALES R, G, B (SEÑALES DE LOS TRES COLORES PRIMARIOS) PARA CADA PIXEL Y EL VALOR MINIMO ES SUMINISTRADO COMO UNA SEÑAL DE VHT (SEÑAL ACROMATICA) A UN PROCESADOR DE SEÑAL DE VELOCIDAD CUADRUPLE (9). LAS SEÑALES R'', G'', B'' (SEÑALES CORREGIDAS DE LOS TRES COLORES PRIMARIOS) SON GENERADAS SUBSTRAYENDO (6, 7, 8) LA SEÑAL DE WHT DE LAS SEÑALES R, G, B, RESPECTIVAMENTE, Y SON SUMINISTRADAS AL PROCESADOR DE SEÑALES DE VELOCIDAD CUADRUPLE (9). EL PROCESADOR DE SEÑALES DE VELOCIDAD CUADRUPLE (9) MULTIPLEXA POR DIVISION DE TIEMPO LAS SEÑALES CORREGIDAS DE LOS TRES COLORES PRIMARIOS Y LA SEÑAL DE WHT PARA GENERAR UNA SEÑAL DE VELOCIDAD CUADRUPLE. PONIENDO {PI} CELDAS (16, 18) EN ON (GIRO DE 0 (GRADOS) ) O EN OFF (GIRO DE 90 (GRADOS) ) EN BASE A LA SEÑAL MULTIPLEXADA POR DIVISION DE TIEMPO, SE OBTIENE UNA IMAGEN EN COLOR QUE UTILIZA CUATRO CAMPOS COMPRIMIDOSEN TIEMPO POR CADA CAMPO ORDINARIO.
