Projector and method of controlling the same
摘要:
A projector includes: a drive motor adapted to drive a lens unit; a control section adapted to control the drive motor; a storage section adapted to store a target position of the lens unit; and a position detector adapted to detect a present position of the lens unit, wherein 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, the control section performs drive of the drive motor with feedforward control until the present position and the target position are coincident with each other, and performs drive control of the drive motor with a predetermined unit based on a deviation between a stop position by the feedforward control and the target position.
