Patent ID: 8773011

Claim:
An endoscopic apparatus for observing an observation object containing hemoglobin, the endoscopic apparatus comprising: a light source device for illuminating the observation object, the light source device comprising: a first light source for emitting a first light having a first wavelength; a second light source for emitting a second light having a second wavelength different from the first wavelength; and a wavelength converter configured to: wavelength-convert the first light to a third light having a third wavelength by absorbing at least a part of the first light and emitting the third light, wherein at least a portion of the wavelength range of the third light is different from the wavelength range of the first light and the wavelength range of the second light, and transmit at least a part of the second light; wherein the first light source and the second light source are configured such that an absorbance by the hemoglobin of the second light at a wavelength corresponding to a peak intensity of the second light is greater than an absorbance by the hemoglobin of the first light at a wavelength corresponding to a peak intensity of the first light.
