Abstract
The position of an image is varied to thereby make it possible to achieve an increase in resolution, and at the same time, easily readjust the variation. The projector includes a vibratory device functioning as an image displacement section adapted to vary the position of the image displayed by the display section, and a control section adapted to control the vibratory device. The control section is provided with a plurality of variable resistors each adapted to adjust amplitude of a drive signal adapted to control a shift amount as the variation of the position of the image due to the vibratory device.
