The imaging device is an imaging optical system that forms an optical image of a subject on an imaging surface, and is a part of the imaging optical system, and is provided so as to be movable in the optical axis direction of the imaging optical system. A zoom lens for enlarging or reducing the optical image formed on the imaging surface, a position detector for detecting the position of the zoom lens in the optical axis direction, and a position corresponding to the position of the zoom lens in the optical axis direction A storage unit that stores output characteristic information related to the output characteristic of the detection unit； and a drive control unit that performs control to move the zoom lens based on the output characteristic information. 撮像装置は、被写体の光学像を撮像面上に結像する撮像光学系と、撮像光学系の一部であって、撮像光学系の光軸方向に移動可能に設けられ、その移動に伴って撮像面上に結像される光学像を拡大又は縮小する変倍レンズと、変倍レンズの光軸方向における位置を検出する位置検出部と、変倍レンズの光軸方向における位置に応じた位置検出部の出力の特性に関する出力特性情報を記憶する記憶部と、出力特性情報に基づいて変倍レンズを移動させる制御を行う駆動制御部とを含む。
