ABSTRACT:
In a white balance adjusting system for plural color television cameras, the output of a video switching unit which selectively switches video signals from television color cameras is applied to a single white balance adjustment circuit, the white balance condition of the selected video signal is detected by the white balance adjustment circuit using a reference value common to the cameras and the output of the white balance adjustment circuit is supplied to the camera selected by the video switching unit. Thus, the white balance of the respective cameras is adjusted.
