Abstract

A projection apparatus includes a light source unit (15) including a plurality of semiconductor light-emitting elements (18, 19), an input unit (11) for inputting a video signal, a projecting unit (12-17) for forming an optical image according to the video signal input by the input unit (11) and projecting the optical image, using light coming from the light source unit (15), and an image converting unit (12) and CPU (28) for simultaneously driving the semiconductor light-emitting elements (18, 19) included in the light source unit (15), and generating a sync signal for use in projecting a stereoscopic image, and correcting gradations ranging from zero gradation to the gradation according to the luminance level of the sync signal, to a specific gradation, when the projecting unit (12-17) forms an optical image of a color complimentary to the color of the sync signal.
