摘要： A video signal is generated representative of a background scene, such as a weather map, which provides an outline of all the detail in the map. This outline detail is made visible to a foreground subject (2) by projecting it onto a white screen (1) behind the subject in a selected color such as green. The projector (3) is selectively inhibited so as to prevent the background detail from projecting onto the foreground subject. The white screen and the green detail lines are removed and replaced by the background scene by an image compositing process. Prompts are visible to the foreground subject, but not visible to a home viewing audience.
摘要翻译：生成表示背景场景的视频信号，例如天气图，其提供了地图中所有细节的轮廓。这种轮廓细节通过将其投射到被选择的对象后面的白色屏幕（1）上，以选定的颜色（例如绿色）使得对于前景物体（2）可见。选择性地抑制投影仪（3），以防止背景细节投射到前景物体上。白色屏幕和绿色细节线被图像合成过程移除并由背景场景替换。提示对于前景主题是可见的，但对于家庭观众来说不可见。

摘要： A video projector (6) shows the desired scene on a projection screen (3). An infrared source (7) close to the video projector uniformly floods the projection screen with non- visible infrared radiation. An infrared sensitive camera (5) observes the projection screen and sees only the uniform illumination of the screen. Upon entry of a subject (4) into the projected video image, the infraged reflected from the subject will not match that of the projection screen and thus the subject area is identified. All pixels of the projected scene, in the area occupied by the subject, are inhibited before reaching the video projector. The subject may then look directly at an audience without being blinded by the projector.
摘要翻译：视频投影仪（6）在投影屏幕（3）上显示所需的场景。靠近视频投影仪的红外线源（7）使投影屏幕以不可见的红外辐射均匀地泛光。红外敏感摄像机（5）观察投影屏幕，只能看到屏幕的均匀照明。当被摄体（4）进入投影视频图像时，从被摄体反射的投影不符合投影屏幕的投影，因此识别主体区域。在到达影像投影机之前，被拍摄对象所占据的区域中的投影场景的所有像素被禁止。然后，该主题可以直接观看观众而不被投影仪蒙蔽。
