PROBLEM TO BE SOLVED: To provide an endoscope apparatus by which stereo measurement may be accurately performed even for a processed image. SOLUTION: A CPU 18a comprises: an original image recording function 180 for recording a still image or a recorded image as an original image; a contrast correction function 181 for performing contrast correction on a still image or a recorded image; a coordinate calculation function 183 for calculating pixel coordinates on an original image which correspond to pixel coordinates designated on a contrast corrected image; a stereo measurement function 184 for performing stereo measurement using pixel coordinates of an original image calculated by the coordinate calculation function 183; a measurement result reflection function 185 for reflecting a measurement result of stereo measurement on a contrast corrected image; and a dynamic range expansion function 186 for enhancing brightness of an image area which is darker than a predetermined threshold.
