Abstract
An endoscope system including a control section that controls an LED driving section to supply driving currents to LEDs of a plurality of colors to cause the LEDs to emit lights in a frame-sequential manner and a processor that divides a total exposure period in one frame period of the frame-sequential light emission into ratios of light emission periods for each of the respective colors obtained by dividing light amount ratios of the lights of the plurality of colors, which should be received in a CCD, respectively by respective maximum light emission intensities of the LEDs of the plurality of colors and sets respective maximum light emission periods of the LEDs of the plurality of colors.
