<P>PROBLEM TO BE SOLVED: To provide an endoscope apparatus in which a user does not need to adjust irradiation light quantity intentionally, and a captured image which is bright and has stable tint can always be obtained without being limited by an imaging distance with respect to the observation of the structure or components of living bodies, such as a surface layer fine blood vessel. <P>SOLUTION: The endoscope apparatus includes: a first light source section 32 that irradiates first narrowband light; a second light source section 34 that irradiates second narrowband light or broadband light; a light source control unit 48 which controls the irradiation and irradiation light quantity, respectively; an imaging unit 26 which obtains a captured image, using return light from an object, to output captured image information; a luminance value calculating unit 50 which calculates the luminance value of the captured image; a light source light quantity changing unit 55 which changes the irradiation light quantity according to the luminance value; a white balance adjustment value calculating unit 57 which calculates a white balance adjustment value for taking the white balance of the captured image from the changed irradiation light quantities; and a gain adjusting unit 59 which adjusts the gain so that the white balance of the captured image becomes a basis white balance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
