Abstract
A white balancing apparatus used for video camera a signal processor for outputting red, green and blue component signals in processing a video signal, an integrator for integrating the output signal of the signal processor, a gate for determining the input video signal whether it is a chromatic signal by using the output signal of the signal processor and for gating the output signal of the signal processor so as to be input to or blocked from the integrator, and a microcomputer for adjusting the gain value of the output signal of the signal processor depending on the output signal of the integrator. Therefore, the white balance performance for the chromatic color components of the photographed object itself is prevented but only the achromatic components are used in performing the white balance, thereby enabling to output cleaner colors.
