Abstract:
1. A projector apparatus comprising: a light source means for outputting a white light; a color wheel means for receiving the white light from said light source means to output a plurality of primary-color lights; a digital micromirror device means for receiving the primary-color lights and for reflecting lights for constituting a picture; a projection optics means for passing the light from said digital micromirror device means to obtain a picture enlarged to a desired size; a shutter disposed downstream of said projection optics means for blocking the light for projection passed through said projection optics means; a sensor means, attached to that surface of said shutter which blocks the light for projection, for detecting a color temperature of the light for projection; and a control means for controlling said color wheel means and said digital micromirror device means such that the light from said digital micromirror device means constitutes a predetermined picture in accordance with data for the picture and for performing, based on detection result from said sensor means, such a control that the color temperature of the light for projection is adjusted to a desired value.
