This endoscope light source apparatus can feed an illuminating light to an endoscope requiring a white color light as an illuminating light and to an endoscope having a field sequential type imaging apparatus and requiring as an illuminating light a field sequential light sequentially switched to lights in different wavelength ranges and comprises a light source emitting a white color light, a converting apparatus interposed in the light path of the light emitted from the light source at least at the time of outputting a field sequential light and converting the white color light emitted from the light source to a field sequential light, a selecting apparatus selecting the kind of the emitted light from among a white color light and field sequential light and a light amount controlling apparatus whereby, when a field sequential light is selected by the selecting apparatus, during the exposure period of the field sequential type imaging apparatus, the light amount of the light source can be increased to be larger than outside the exposure period. Also, the endoscope light source apparatus comprises a light source, converting apparatus, selecting apparatus and light amount controlling apparatus whereby, when a field sequential light is selected by the selecting apparatus, the light amount of the light source can be increased to be larger than at the time of outputting a white color light.
