摘要： A video communication system may include a computer program that implements a feedback control process for automatically controlling a light. The feedback control process may include receiving an image from a video camera and determining an initial difference between the received image and a stored image. For example, the feedback control process may determine, on a pixel-by-pixel basis, whether the color and intensity of a facial region in the captured image is sufficiently close to the color and intensity of a facial region in the stored image. If the difference between the captured image and the stored image exceeds a threshold, the feedback control process includes transmitting an optimization instruction to the light. This optimization instruction, when performed by the light, decreases the difference between the received image and the stored image.
