Abstract
An endoscope system includes a color image sensor, having pixels sensitive to plural colors different from one another, for imaging an object. Plural LEDs discretely generate light of colors different from one another, to apply polychromatic light constituted by spectrally combining the light of the colors to the object. A light source controller controls the plural LEDs, to correct an intensity ratio of an integrated emission intensity between the plural colors according to receiving the first polychromatic light with respectively the pixels of the plural colors, so that the intensity ratio becomes equal to a target ratio of an integrated emission intensity between the plural colors according to receiving continuous spectrum light with respectively the pixels of the plural colors, the continuous spectrum light having an at least partial wavelength range of light emitted by a white light source.
