ABSTRACT:
A color printer is equipped with a digital micromirror device having at least one micromirror array constituted of a number of micromirrors. Each micromirror changes its tilt angle in accordance with a value of mirror drive data of one bit. As the mirror drive data takes a value "1", the micromirror reflects spot light toward color paper, whereas as the mirror drive data takes a value "0", it reflects spot light toward a light absorption plate. During red exposure, red light from a red LED unit is incident upon the digital micromirror device which is then driven by red mirror drive data to expose a red image on the color paper. Next, during radiation of a green LED unit, the digital micromirror device is driven by green mirror drive data to expose a green image on the color paper. Lastly, a blue image is exposed on the color paper by using a blue LED unit. A full-color image is therefore printed on the color paper through three-color line- or frame-sequential exposure.
