PROBLEM TO BE SOLVED: To provide an endoscope system capable of obtaining an image having a high color reproducibility even if a white balance is adjusted under a condition where blockage of external light is insufficient.SOLUTION: An endoscope system includes a video processor. The video processor includes a light source controller to control emission and blockage of illumination light from a light source when external light is emitted to an object when adjusting a white balance, an intensity acquisition part to obtain intensities of image signals by a color component, an intensity calculation part to obtain a difference by the color component between the intensities obtained by the intensity acquisition part during the emission and the blockage of the illumination light, a brightness adjuster capable of adjusting brightnesses of an image based on the image signals for the emission and the blockage of the illumination light, and a controller to control the brightness adjuster and the intensity calculation part to allow for calculation of a white balance adjustment value corresponding to the image signals on the basis only of the illumination light from the light source.SELECTED DRAWING: Figure 1 |
