IMAGE DISPLAY APPARATUS, VOLTAGE CONTROL METHOD AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technique for reducing power consumption in an image display apparatus for forming an image on a projection surface by scanning an output beam emitted from a light source. SOLUTION: The image display apparatus includes the light source and a scanner for scanning an output beam emitted from the light source to form an image on the projection surface by scanning the output beam by the scanner. The image display apparatus includes also: a light source driver that controls light quantity of the output beam emitted from the light source by controlling a drive current of the light source on the basis of input image data; a light source driving power supply that supplies power to the light source driver; and a voltage controller that controls an output voltage from the light source driving power supply on the basis of the input image data.
