ABSTRACT:
The present invention provides a projection apparatus, comprising: a light source; at least one spatial light modulator for modulating illumination light from the light source by a plurality of pixel elements by using different modulation states; 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 has a function of receiving data corresponding to the control signal generated by the spatial light modulator control unit, controlling a parameter of an emission pulse of the illumination light emitted from the light source, and thereby adjusting an emission intensity of the illumination light.
