摘要： A telestrator system is disclosed that allows a broadcaster to annotate video during or after an event. For example, while televising a sporting event, an announcer (or other user) can use the present invention to draw over the video of the event to highlight one or more actions, features, etc. In one embodiment, when the announcer draws over the video, it appears that the announcer is drawing on the field or location of the event. Such an appearance can be performed by mapping the pixels location from the user's drawing to three dimensional locations at the event. Other embodiments include drawing on the video without obscuring persons and/or other specified objects, and/or smoothing the drawings in real time.

摘要： Pan, tilt and zoom sensors are coupled to a broadcast camera in order to determine the field of view of the broadcast camera and to make a rough estimate of a target's location in the broadcast camera's field of view. Pattern recognition techniques can be used to determine the exact location of the target in the broadcast camera's field of view. If a preselected target is at least partially within the field of view of the broadcast camera, all or part of the target's image is enhanced. The enhancements include replacing the target image with a second image, overlaying the target image or highlighting the target image. Examples of a target include a billboard, a portion of a playing field or another location at a live event. The enhancements made to the target's image can be seen by the television viewer but are not visible to persons at the live event.

摘要翻译： 平移，倾斜和变焦传感器耦合到广播摄像机，以便确定广播摄像机的视野并且在广播摄像机的视场中粗略地估计目标的位置。 可以使用模式识别技术来确定目标在广播摄像机的视场中的确切位置。 如果预选目标至少部分地在广播摄像机的视野范围内，则全部或部分目标的图像被增强。 增强功能包括用第二个图像替换目标图像，覆盖目标图像或突出显示目标图像。 目标的示例包括广告牌，游戏场的一部分或实况事件中的另一位置。 对目标图像的增强可以由电视观看者看到，但对于现场直播活动的人来说是不可见的。
