Abstract
PURPOSE:To contrive to keep the homogeneity of a major object by using a control means adjusting the white balance of a video signal based on a color temperature data so as to fetch an output signal of an operating means and a setting output of a single shot/consecutive shot mode setting means thereby inhibiting the revision of a color temperature data used for white balance adjustment in case of the consecutive shot mode. CONSTITUTION:A control section 16 consists of a microcomputer or the like and controls each section in response to a vertical synchronizing signal VD supplied to a control line 32 from a synchronizing generating section 30. When the vertical synchronizing signal VD is inputted, a color temperature data DT is fetched from an A/D converter 56. Then whether or not a difference DX between the color temperature data D0 and the color temperature data DT varies in the same direction as the time elapses is discriminated. Moreover, the image pickup mode is discriminated, and when the setting of the still mode is discriminated, whether or not the consecutive shot mode is discriminated. Since the correlativity of a photograph picked up consecutively is high in the consecutive shot mode the same as the movie mode, the revision of the color temperature data D0 is inhibited so as not to change the color of the major object.
