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.
