Abstract: A videoconference apparatus and method coordinates a stationary view obtained with a stationary camera to an adjustable view obtained with an adjustable camera. The stationary camera can be a web camera, while the adjustable camera can be a pan-tilt-zoom camera. As the stationary camera obtains video, participants are detected and localized by establishing a static perimeter around a participant in which no motion is detected. Thereafter, if no motion is detected in the perimeter, any personage objects such as head, face, or shoulders which are detected in the region bounded by the perimeter are determined to correspond to the participant.

Abstract: A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.

Abstract: A videoconferencing system includes at least one processor and at least one camera. The endpoint can capture one or more images with the camera. The system can locate a region of interest within an image, such as the area surrounding the face of a person participating in a videoconference. If the face area or other region of interest is too dark, the system can brighten the region to make it more visible. The system can determine whether the face is too dark by comparing the captured image to previously captured images, or comparing the luma values and other data making up the face to predetermined values, or both. The system can check the modified image for over-brightening or saturation, and further adjust the image as needed. The brightening of the face area is done in such a way that the brightened region is unobtrusive to the viewer.
Abstract translation: 视频会议系统包括至少一个处理器和至少一个相机。 端点可以使用相机捕获一个或多个图像。 系统可以在图像内定位感兴趣的区域，例如参与视频会议的人的面部周围的区域。 如果脸部区域或其他感兴趣区域太暗，系统可以使该区域变亮以使其更可见。 通过将捕获的图像与先前捕获的图像进行比较，或将亮度值和构成面部的其他数据比较为预定值，或者两者，系统可以确定脸部是否太暗。 系统可以检查修改后的图像是否过亮或饱和，并根据需要进一步调整图像。 面部区域的增白以这样的方式完成，使得增亮区域对观察者不引人注意。
