Patent ID: 8878478

Claim:
A projector, comprising: a drive motor adapted to drive a lens unit; a storage section adapted to store a target position of the lens unit; a position detector adapted to detect a present position of the lens unit; and a control section adapted to control the drive motor, determine if a deviation between the target position stored in the storage section and the present position detected by the position detector is equal to or larger than a predetermined value, and if the deviation between the target position and the present position is determined to be equal to or larger than the predetermined value, perform drive of the drive motor with feedforward control until the present position and the target position are coincident with each other and perform drive control of the drive motor with a predetermined unit of movement of the drive motor based on a deviation between a stop position by the feedforward control and the target position, wherein the control section performs the drive control with the predetermined unit of movement of the drive motor by the drive motor by the number of times of movement with the predetermined unit of movement of the drive motor obtained based on the following formula: N =INT( X/W+ 0.5) (where N denotes the number of times of movement by the predetermined unit of movement of the drive motor, X denotes the deviation between the stop position by the feedforward control and the target position, and W denotes the predetermined unit of movement of the drive motor).
