Abstract

Método para ajustar automáticamente al menos una imagen proyectada (9-9A), siendo cada imagen (9-9A) proyectada por un proyector (1-1A) que genera una serie de haces luminosos de distinto color, siendo la imagen proyectada (99A) ajustada automáticamente con respecto a la convergencia, a la geometría, a la geometría de adyacencia y/o geometría de solapamiento, al enfoque, al astigmatismo, a la modulación de contraste, a la corrección de gamma, al borde amortiguado y/o al envejecimiento del tubo de imagen, p. ej.; estando el método caracterizado por el hecho de que durante el uso normal del proyector (1-1A) y después de un período de tiempo inicial para corrección es realizado un ajuste automático por medio de modelos matemáticos que están basados en los factores influyentes que son relevantes para los ajustes particulares y varían con el tiempo de funcionamiento del proyector.
