Abstract:
Video frames are captured at one or more cameras during a video conference session, where each video frame includes a digital image with a plurality of pixels. Depth values associated with each pixel are determined in at least one video frame, where each depth value represents a distance of a portion of the digital image represented by at least one corresponding pixel from the one or more cameras that capture the at least one video frame. Luminance values of pixels are adjusted within captured video frames based upon the depth values determined for the pixels so as to achieve relighting of the video frames as the video frames are displayed during the video conference session.
