1. An imaging apparatus having an optical zoom mechanism, comprising: an imaging section; a correcting section which corrects a viewing angle of an image captured by the imaging section in accordance with a difference between a current position and a target position of a zoom lens obtained when a zoom operation of the optical zoom mechanism is performed; a display section which displays the image corrected by the correcting section; and a backlash control section which, when stopping the zoom lens, which is being moved in a predetermined direction, at a predetermined target position, performs a backlash control operation in which the zoom lens is moved by an extra distance and then returned back to the predetermined target position, wherein the correcting section corrects the viewing angle of the image captured by the imaging section in accordance with a backlash amount that is the difference between the current position and the target position of the zoom lens when the backlash control operation is being performed.
