ABSTRACT:
The camera function of a video conferencing system is enhanced such that it will operate in an automatic adjustment mode for brightness and color for only a predetermined period of time, and only at power up and reset. Once the predetermined period of time has elapsed, the camera function "locks down" the operating parameters for brightness and color, and switches to a manual adjustment mode. As a result, video image substantially close to the "ideal image" in brightness and color can be acquired, and yet valuable processor cycles are not wasted in compensating for temporal foreground changes, but instead made available to sustain better frame rates.
