    • An image projection system comprises an image projector, such as a film or television projector and a projection screen. The projection screen is fabricated of a substantially transparent material, such as glass or plastic. The screen of transparent material has one or more areas or portions formed therein which areas or portions may be made to be translucent upon the application of a stimulus. Once in a translucent condition, the projected image can be received and viewed on the translucent portion. A mirror can be positioned behind the projection screen so that a person can view the reflection of themselves in the mirror when the screen is transparent, and an image can be projected when the projection screen is made to be substantially translucent.
    • 图像投影系统包括诸如电影或电视投影仪和投影屏幕的图像投影仪。 投影屏幕由诸如玻璃或塑料的基本上透明的材料制成。 透明材料的屏幕具有形成在其中的一个或多个区域或部分,其中可以在施加刺激时将这些区域或部分制成为半透明的。 一旦处于半透明状态,可以在半透明部分上接收和观看投影图像。 镜子可以位于投影屏幕的后面,使得当屏幕是透明的时候,人们可以在镜子中观察自身的反射,并且当投影屏幕被制成基本半透明时,可以投影图像。
