ABSTRACT:
The disclosed image sensing device includes a sensing arrangement for converting an optical image into an electrical signal; an iris for adjusting the quantity of light supplied to the image sensing arrangement; gain control circuits for adjusting amplification gains of monochrome or color difference signals obtained from the image sensing arrangement; a peak detecting arrangement for detecting the peak values of the monochrome or color difference signals; a balance control for controlling the gain control circuits for white balance adjustment according to the signals obtained from the peak detecting arrangement; and an iris control for controlling the iris such that the output of the image sensing arrangement becomes lower when the gain control circuits are under the control of the balance control than when they are under a normal photographic condition.
