ABSTRACT:
A projection apparatus includes a light source for emitting a light including at least two different wavelengths; a light source control circuit for controlling a light source to emit the light as pulse emissions with a pulse modulation control; at least two spatial light modulators each comprises plurality of pixel elements are arranged in an array; a spatial light modulator control circuit for selectively controlling a modulation state of the respective pixel elements in each of the spatial light modulators in accordance with image data corresponding to the respective pixel elements; and the light source control circuit controls the light source so that a starting time of a pulse emission period of the pulse emissions of at least one of the wavelengths emitted from the light source is different from a modulation control timing of the pixel element of the spatial light modulator.
