Patent ID: 11039739

Abstract:
There is provided an endoscope system capable of maintaining a constant light amount ratio for each wavelength of light emitted from an endoscope.The endoscope system has: an endoscope that has a light guide; two or more light sources that supply light to the light guide and have different main wavelengths; a light source driving unit that supplies a driving signal to each of the light sources; a light source control unit that makes the light source driving unit generate a driving signal corresponding to the light amount setting value; and a light source information storage unit that stores information of the main wavelength. The endoscope has a scope information storage unit that stores information of a scope type. The light source control unit adjusts a light amount ratio of the light source to a preset light amount ratio by acquiring the information of the main wavelength of the light source from the light source information storage unit, acquiring the information of the scope type from the scope information storage unit, setting the light amount setting value according to at least the information of the main wavelength and information of a length of the light guide obtained from the information of the scope type, and inputting the light amount setting value to the light source driving unit to control a light emission amount of the light source driven by the light source driving unit.
