載のカラービデオカメラのホワイトバランス機構
。[Scope of Claim for Utility Model Registration] [1] An automatic device configured to automatically generate a white balance adjustment signal based on the color temperature detection result of incident light from a subject by a color sensor and supply it to a video signal processing circuit. A white balance mechanism for a color video camera comprising a white balance circuit, wherein the light incident on the color sensor from a subject is weaker than the standard illuminance, and the color sensor has a dark current that A white balance mechanism for a color video camera, comprising a bias light for irradiating the color sensor with bias light having a constant illuminance capable of outputting a large current. [2] The white balance mechanism for a color video camera according to claim 1, wherein the bias light is configured to be able to adjust the illuminance of the bias light emitted thereby.
