(54)ENDOSCOPE APPARATUS, CALIBRATION DEVICE, AND CALIBRATION METHOD


(57) There are provided an endoscope apparatus (10) that can display a measurement marker used to measure the size of a subject in consideration of the influence of a distortion and the like caused by an image pickup optical system (29b), a calibration device (200), and a calibration method.
An image acquisition unit (38) acquires a picked-up image obtained from image pickup of a subject illuminated with illumination light and auxiliary measurement light. A display control unit (40) causes an observation display unit (18) to display a specific image where a first measurement marker used to measure the size of the subject is superimposed on the picked-up image. The display control unit performs control where the display aspect of the measurement marker varies according to the irradiation position of auxiliary measurement light and a marker display position on the picked-up image.
