This endoscope device can simplify the determination of the moving direction of a focusing lens, and can improve the accuracy of auto focusing. The endoscope has the following elements: an optical system (14) having a focusing lens (14a) a lens moving unit (15) which moves the focusing lens along an optical axis thereof an image capturing unit (17) which obtains an optical image of an object from the optical system as a plurality of images each of which has a different focal position from each other a moving direction determining section (31) which determines whether to change the observation depth on the basis of the plurality of images, and determines a moving direction toward which the focusing lens is to be moved on the bases of the images and a drive control unit (27) which controls the lens moving unit to move the focusing lens toward a determined moving direction.
