ABSTRACT:
In an automatic white balance control circuit for adjusting gain levels of a plurality of color signals included in a video signal composed of successive fields and received from a video camera while a light source provides illumination for the scene in the field of view of the camera; first, second and third integrators generate integration signals for each of the received color signals in each of first, second and third fields, respectively, a control signal for each of the fields is generated on the basis of the respective integration signals, and gain levels of at least two of the color signals are adjusted in response to the control signal so as to perform white balancing for preventing variation in video signal brightness or flicker, such as is caused by a difference between the video camera exposure frequency and the light source power supply frequency.
