摘要 |
A display position control device for projection image which controls a display position of a projection image displayed on a projection surface includes: a display position adjustment control unit which divides display position shift amount from a display target position of the projection image on the projection surface into a value an integer number times larger than a pixel pitch of the projection image and a value smaller than the pixel pitch; a display position control processing unit which performs display position control through image processing based on the value the integer number times larger than the pixel pitch; and a display position control mechanism which performs optical display position control based on the value smaller than the pixel pitch. |
