Provided is an endoscope apparatus (1) including a light-guiding means (11) that guides illumination light emitted from a light source to the distal end of an inserted portion (2) a scanning means (12) that makes the light-guiding means vibrate with a predetermined period, thus two-dimensionally scanning the illumination light emitted from the inserted portion on an observation subject an image-acquisition means (25) that receives return light of the illumination light coming from the observation subject and that generates an image signal based on a position scanned by the scanning means and an intensity of the return light and a light-source control means (21) that controls the light source so as to change the intensity of the illumination light emitted from the inserted portion in accordance with an angle formed between the longitudinal direction of the inserted portion and a direction in which the illumination light is emitted toward the observation subject.
