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.
