ENDOSCOPE SYSTEM

摘要

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.

1. An endoscope system comprising:
light emitting elements of a plurality of colors that generate lights of the plurality of colors to be radiated on a subject; a light-emitting-element driving section that supplies driving currents to the light emitting elements of the plurality of colors and causes the light emitting elements to emit lights; a control section that controls driving of the light-emitting-element driving section to cause the light emitting elements of the plurality of colors to emit lights in a frame-sequential manner according to an input signal; and a processor that divides a total exposure period in the 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 corresponding to ratios of light amounts which should be received in an image pickup device that generates an image pickup signal of the subject, respectively, by respective maximum light emission intensities obtained when light emission intensities of the light emitting elements of the plurality of colors are maximized and sets respective maximum light emission periods of the light emitting elements of the plurality of colors in one frame period of frame-sequential light emission.
