OPERATION DEVICE, OPTICAL DEVICE AND IMAGING DEVICE

To provide an operation device advantageous in operation property of an operation member.SOLUTION: An operation device (10) for controlling a movable optical element to vary optical characteristics of an optical device has: an operation member (101); a detection unit (102) that detects an operation amount of the operation member; and a control unit (103) that generates a command value for the control based on the operation amount. The control unit controls a display unit to display a first region corresponding to the range of the command value or of a possible value of a control amount in the control, a first index that shows the command value or the control value in association with the first region, a second region corresponding to the range of a possible value of the operation amount, and a second index that shows the operation amount in association with the second region.SELECTED DRAWING: Figure 1 【課題】 操作部材の操作性の点で有利な操作装置を提供すること。【解決手段】 光学装置の光学特性を変更するために可動の光学素子を制御するための操作装置（１０）は、操作部材（１０１）と、操作部材の操作量を検出する検出部（１０２）と、操作量に基づいて、上記制御のための指令値を生成する制御部（１０３）と、を有する。制御部は、指令値または制御における制御量がとりうる値の範囲に対応する第１領域と、指令値または制御量を第１領域に関連づけて示す第１指標と、操作量がとりうる値の範囲に対応する第２領域と、操作量を第２領域に関連づけて示す第２指標とを表示部に表示させる。【選択図】 図１
