項１記載の内視鏡用カラーテレビジヨン装置。[Claims for Utility Model Registration] 1. An endoscope including a light source device for an endoscope, a light guide that guides illumination light from the light source device to a subject, and converting an optical image of the endoscope into an electrical signal. In a color television device for an endoscope combined with a color television camera, a color temperature detection unit for the light source device and the color temperature detection unit detect illumination light of the light source device from the tip of the endoscope. An illumination light reception detection means for detecting the reception of light is provided, and the output signal of the illumination light reception detection means detects the image of the corresponding color channel of the color television camera according to the output signal of the color temperature detection unit. A color television device for an endoscope, characterized in that the white balance adjustment circuit means for automatically adjusting the gain of an amplifier is activated. 2. The illumination light reception detection means includes a level detection means for detecting and outputting that the output signal level of the color temperature detection unit is equal to or higher than a predetermined level, and a timer for detecting and outputting that the detected output level continues for a predetermined time or more. 2. A color television device for an endoscope according to claim 1, characterized in that it comprises means.
