ABSTRACT:
An image pickup device capable of white balance control, independent from the color of light source or from the change in color temperature, without the influence of the object of high saturation and with adaptation to the change in color of the light source, and also capable of avoiding unpleasant color shift not matching the direction of color temperature change, is provided by detecting the luminance of external light and the presence of flicker by the microprocessing unit from the output of a photometry sensor, then accordingly varying the clipping range of a clipping circuit, also switching the method of calculating the white balance control values R.sub.CD, B.sub.CD and varying the range of color correcting direction by the amplifiers.
