More Information
Summary:An endoscope apparatus includes a CCD disposed at a distal end portion of an endoscope insertion section, a first LED and a second LED functioning as illumination-light emitting unit, a region setting section that sets a first region where illumination by the first LED is predominant on an endoscopic image and a second region where illumination by the second LED is predominant on the endoscopic image, and a white balance circuit that respectively calculates color balance values corresponding to the first and second regions and applies correction processing to a color balance value of a video signal of the entire endoscopic image on the basis of results of the respective calculations.
