Abstract

Un tubo de imágenes a color mejorado incluye una máscara de sombras y una pantalla de puntos, en donde la máscara es rectangular y tiene dos lados horizontales y dos lados cortos verticales. Los lados largos están en paralelo con un eje mayor central de la máscara y los lados cortos están en paralelo con un eje menor central de la máscara. La máscara incluye una matriz de aberturas dispuestas en columnas verticales y filas horizontales. Las aberturas en una fila están en columnas diferentes que las de las aberturas en filas adyacentes. La separacion vertical entre las aberturas en la misma columna es el paso vertical de las aberturas y la separacion horizontal entre aberturas en la misma fila es el paso horizontal de las aberturas. La mejora comprende el paso horizontal de las aberturas incrementándose desde el eje menor a los lados cortos de la máscara y disminuyendo del eje mayor a los lados largos de la máscara. También, a lo largo del eje mayor, el paso vertical de la máscara disminuye desde el centro a los lados cortos de la máscara y, adyacente a los lados largos de la máscara, se incrementa desde el eje menor a las esquinas de la máscara.
