Abstract
A white balance control system comprises a ripple detecting circuit for detecting a ripple component associated with a fluorescent lamp source or the like which is contained in light from an object being photographed. Alternatively a circuit may be provided for detecting a particular color temperature from color temperature information which is used in a white balance control. A white balance adjusting circuit responds to an output from either the ripple detecting circuit or the detecting circuits to provide a correction for any offset in the white balance control.
