System configurations and methods for controlling image projection apparatuses |
摘要 |
A projection apparatus comprising a light source for emitting incident light and a mirror device that includes a plurality of mirror elements each guiding the incident light to the ON position towards a projection light path under pulse width modulation (PWM) control corresponding to one frame or sub-frame or to the OFF state so as not to guide the incident light to a projection path. The light source is turned off outside the period in which the mirror element with the maximum brightness is in the ON state.
