Abstract

Un controlador de proyector incluye un detector de objetos y electrónica de control, y se configura para proteger a los miembros de audiencia de luz intensa que impone una zona de exclusión en frente de un proyector. El detector de objetos se configura para detectar ópticamente una presencia de un objeto en una región de detección debajo de la zona de exclusión y por encima de los miembros de audiencia. La electrónica de control se configura para controlar el proyector cuando el detector de objetos indica la presencia del objeto en la región de detección. Un método para proteger a los miembros de audiencia de luz intensa que impone una zona de exclusión en frente de una salida de un proyector incluye: (i) detectar ópticamente una presencia de un objeto en una región de detección entre la zona de exclusión y los miembros de audiencia, y (ii) controlar el proyector cuando se detecta la presencia del objeto en la región de detección.
