System configurations and methods for controlling image projection apparatuses
First Claim
1. A mirror device comprising a plurality of deflectable mirrors for reflecting a light, whereinthe mirror is controllable to deflect to a first direction during an incident period with the light incident to the deflectable mirror and at an end of the incident period the mirror is controllable to deflect to a second direction opposite to the first direction during a non-incidence period when the light is not incident to the mirror.

Abstract
The mirror device comprising a plurality of deflectable mirrors for reflecting light, wherein the mirror is controllable to deflect to a first direction during an incident period with the light incident to the deflectable mirror and at an end of the incident period the mirror is controllable to deflect to a second direction opposite to the first direction during a non-incidence period in which the light is not incident to the present mirror.

3. A projection apparatus, comprising:
-
a light source for projecting a light; and a mirror device comprising a plurality of deflectable mirrors for reflecting the light projected from the light source, wherein the mirror is controllable to deflect to a first direction during a turn-on period of the light source and at an end of the incident period the mirror is controllable to deflect to a second direction opposite to the first direction during a turn-off period of the light source. - View Dependent Claims (4, 5)

6. A method for controlling a mirror device comprises a deflectable mirror for reflecting light and an electrode for deflecting the mirror, wherein:
-
connecting the electrode to a bit line and a word line by way of a capacitor and a transistor, and inverting the polarity of the bit line after an end of an incidence period when the light is incident onto the deflectable mirror. - View Dependent Claims (7, 8)

9. A projection apparatus comprising:
-
a light source for projecting a light; and a spatial light modulator for modulating the light using a first control data generated from an externally inputted image data, wherein the spatial light modulator is controlled by applying a second control data different from the first control data after an end of a control period by applying the first control data. - View Dependent Claims (10, 11, 12)

13. A method for controlling a projection apparatus comprises a mirror for modulating a light emitted from a light source by applying a first control data generated from an externally inputted image data, comprising:
-
maintaining said mirror in the first direction until a time immediately before turning off the light source after the mirror is deflected to a first direction; turning off the light source; and deflecting the mirror to a second direction opposite to the first direction. - View Dependent Claims (14, 15, 16, 17)
