A display system includes a spatial light modulator for displaying a image by the modulation state of a plurality of micromirrors, and a control device for controlling the spatial light modulator. The control device includes a data conversion device for converting the digital image data into non-binary data, and a modulation-control device for generating a modulation control signal for micromirrors depending on the non-binary data, and controlling the spatial light modulator. The modulation state of the micromirrors by the modulation control signal includes modulation by oscillation of the micromirrors. The modulation control signal controls amplitude of the oscillation to be smaller than the maximum amplitude of the micromirrors in the modulation by the oscillation of the micromirrors. The oscillation having smaller amplitude than the maximum amplitude of the micromirrors is repeated by the modulation control signal in an optional time duration or frequency.
