<p>An endoscope observing device (1) measures the accurate absolute distance to the subject from the end of an illuminating section for illuminating the subject with light and acquires an image of the quantitative subject irrespective of the distance to the subject. The endoscope observing device (1) comprises the illuminating section (12) at the end of an insertion body (6) inserted into a body cavity for illuminating the subject facing to the end of the insertion body with light, a light receiving section (12) for receiving an observation light reflected from the subject, an ultrasonic sensor (13) for measuring the absolute length between the insertion body (6) and the subject by generating an ultrasonic wave, a correcting section (32) for correcting luminance information on the observation light according to the absolute distance acquired by the ultrasonic sensor (13), and an image producing section (32) for producing an image of the subject according to the illumination information on the observation light corrected by the correcting section (32).</p> |
