Abstract:
A video conferencing apparatus comprising:an image analysis circuit to analyze a subset of pixels included within a video conferencing image to detect an object displayed within the image, wherein the image analysis circuit analyzes the subset of pixels to determine a level of disparity between the pixels within the subset and to determine whether the level of disparity between the pixels within the subset exceeds a threshold value, and wherein if the level of pixel disparity within the subset of pixels does not exceed a threshold value, the image analysis circuit enlarges the subset of pixels and analyzes the enlarged subset of pixels to determine if a level of pixel disparity within the enlarged subset exceeds a threshold value; and a control circuit, coupled to the image analysis circuit, to control a remote video camera of a remote conferencing apparatus communicatively coupled to the video conferencing apparatus to conduct the video conference, responsive to the results of said analysis.
