ABSTRACT:
The present invention provides a projection apparatus, comprising: a light source for emitting illumination light; at least one spatial light modulator with a plurality of movable mirrors corresponding to pixels to be displayed, for performing a modulation of the illumination light through operation of the movable mirrors; a light source control unit performing a modulation control of the light source; and a spatial light modulator control unit generating, from an input image signal, a control signal for driving the spatial light modulator, wherein: the light source control unit adjusts a pulse emission frequency of an emission pulse of the illumination light emitted from the light source while corresponding to an oscillation frequency of the movable mirrors.
