The control unit 20 instructs the OSD processing unit 32 to project and display the lens adjustment status of the adjustment mechanism superimposed on the input image based on the adjustment operation (step S102). Further, the control unit 20 instructs the display control unit 27 to display the lens adjustment status of the adjustment mechanism based on the adjustment operation on the display unit 28 (step S103).

Here, the lens adjustment screen of the display unit 28 will be described.

An adjustment operation is performed (step S104). Next, the control unit 20 determines whether or not an adjustment operation end operation has been performed (step S105). If the end operation of the adjustment operation has not been performed (step S105: NO), the process proceeds to step S101 to perform display and lens adjustment operation based on the adjustment operation.

  If the adjustment operation end operation has been performed (step S105: YES), the control unit 20 instructs the OSD processing unit 32 to end the lens adjustment display by the OSD (step S106). Then, the control unit 20 instructs the display control unit 27 to end the lens adjustment display on the display unit 28 and return to the display state before the lens adjustment processing (step S107).
