Abstract

Desde que se diseñó para proporcionar con circuitos de conversión A/D 30r, 30g y 30b convirtiendo para señales analógicas de salida R, G y B a señales digitales, un circuito de generación de señal Y 36 genera señales Y a partir de estas señales digitales R, G y B, un circuito de extracción de contorno extrae los componentes del contorno de la señal Y generada, y sumadores de contorno 34r, 34g y 34b a las señales de salida (R+Yer), (G+Yeg) y (B+Yeb) con contorno enfatizado agregando este componente de contorno a la salida de las señales R, G y B de los circuitos de conversión A/D 30r, 30g y 30b, y pueden sacarse agregando los componentes del contorno después de convertir las señales analógicas R, G y B a señales digitales por medio de los circuitos de conversión A/D 30r, 30g y 30b, ningún componente de énfasis de contorno está encima del margen dinámico del circuito de conversión A/D, como un ejemplo anterior después de añadir componentes del contorno a las señales analógicas R, G y B. Por esta razón, en caso de que las señales analógicas R, G y B entren en el circuito de énfasis de contorno de la presente invención, e incluso en el caso de que la cantidad de énfasis de contorno sea "grande", no se produce ni la aglomeración de blanco ni la aglomeración de negro cuando se visualiza un vídeo por medio de la salida de una señal del circuito de énfasis de contorno de la presente invención al dispositivo de visualización controlado por una señal de vídeo digital.
