Abstract
In a projection apparatus, a processor performs a light-source controlling process of simultaneously driving the semiconductor light-emitting elements included in the light source unit and of generating a sync signal for use in projecting a stereoscopic image, and a gradation controlling process of 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 forms an optical image of a color complimentary to the color of the sync signal generated by the light-source controlling unit.
