Abstract:
1. A projector controllable by remote operation using a remote controller, comprising: a lens position control unit which controls a projection position of an image by shifting a projection lens; a signal receiving unit which receives a position control start signal for allowing the lens position control unit to start position control and a lens shift signal for specifying a shift direction and shifting the projection lens in the specified shift direction based on input from the remote controller, the shift direction being perpendicular to an axis of the projection lens; a direction conversion memory unit which stores direction conversion information corresponding to the lens shift signal received by the signal receiving unit as information for performing a predetermined conversion of the shift direction of the projection lens, the direction conversion information being based on user input of a normal position or a suspended position of the projector; a shift direction converting unit which converts the shift direction of the projection lens based on the direction conversion information stored in the direction conversion memory unit; a menu display unit which displays a direction conversion menu screen through which the direction conversion information is inputted; and a control unit which allows the menu display unit to display the direction conversion menu screen when a predetermined condition is satisfied at the time of reception of the position control start signal by the signal receiving unit.
