ABSTRACT:
A high accurate image of a specimen is obtained by accurately measuring a distance between the specimen and a tip of a light emitting portion that irradiates a light to the specimen. An endoscope observation device includes the light emitting portion that irradiates the light to the specimen and a light receiving portion that receives an observation light returning from the specimen so as to form an image of the observation light received by the light receiving portion. The endoscope observation device is equipped with a distance measurement unit that measures an absolute distance between the tip of the insertion portion and the specimen through an interference of the low coherence light, a correction unit that corrects the brightness information of the observation light based on the absolute distance measured by the distance measurement unit, and an image forming unit that forms the image of the specimen based on the brightness information of the observation light corrected by the correction unit.
