ABSTRACT:
An automatic white balance adjusting device in which white balance adjustment is performed by feedback controlling gains for color signals obtained from an image pickup element, comprising a first computing circuit for computing the color signals, a circuit for producing control signals for controlling the gains of the color signals on the basis of a signal output from the first computing circuit, a second computing circuit for computing the color signals in a different operation from that of the first computing circuit, and a circuit for correcting the control signals on the basis of a signal output from the second computing circuit.
