Abstract

SE PRESENTAN UN METODO Y UN APARATO DE PROCESAMIENTO DE IMAGENES A COLOR CON LOS QUE ES POSIBLE LLEVAR A CABO UN PROCESAMIENTO POR CODIFICACION DE ALTA VELOCIDAD DE LOS DATOS DE IMAGEN QUE CONTIENEN DATOS INDICATIVOS DE LOS ESPACIOS EN BLANCO. CUANDO SE EJECUTA EL PROCESAMIENTO POR CODIFICACION, UNA CPU POSICIONA LOS DATOS, QUE SE AÑADEN A MODO DE ESPACIO EN BLANCO O MARGEN, EN UNA MEMORIA DE POSICIONAMIENTO DE VALORES EN BLANCO Y UN DSP DE PROCESAMIENTO POR CODIFICACION COLOCA EN MEMORIA EL VALOR DE POSICIONAMIENTO ANTES DE COMIENCE EL PROCESAMIENTO POR CODIFICACION, LLEVA A CABO UNA TRASFORMACION A UN ESPACIO A COLOR PARA PROCESARLO POR CODIFICACION Y ALMACENA LOS DATOS RESULTANTES EN SU PROPIA MEMORIA INTERNA DE MODO QUE LOS DATOS ALMACENADOS EN LA MEMORIA INTERNA SE PUEDAN UTILIZAR PARA CODIFICAR LAS AREAS EN BLANCO Y SE PUEDA LLEVAR A CABO UN PROCESAMIENTO POR CODIFICACION DE ALTA VELOCIDAD.
