Abstract
A new light balancing system using an electrically-controllable liquid crystal has been developed for video image pickup. The fabricated system can automatically and rapidly compensate the color balance of pickup image by sensing color temperature of environmental illumination and driving the active filter. It is useful for video locations where camera is moved under different illumination sources like solar light and indoor incandescent lamps.
