STABILIZED PICO-PROJECTOR DEVICE AND RELATED IMAGE STABILIZATION METHOD
First Claim
1. A pico-projector device, comprising:
- a light source operable to generate a light beam as a function of an image to be generated;
a mirror mechanism operable to direct the light beam towards a displaying surface; and
a driving circuit configured to supply driving signals for movement of said mirror mechanism, said driving circuit further comprising a compensation stage configured to receive angular velocity signals from a gyroscopic sensor coupled to said pico-projector device, and to generate said driving signals as a function of said angular velocity signals, thereby stabilizing the image projected on said displaying surface with respect to undesired movements of said pico-projector device.

Abstract
A pico-projector device includes a light source operable to generate a light beam as a function of an image to be generated, a mirror mechanism operable to direct the light beam towards a displaying surface, and a driving circuit that supplies driving signals for controlling movement of the mirror mechanism. The driving circuit includes a compensation stage that receives angular velocity signals from a gyroscopic sensor coupled to the pico-projector device and generates the driving signals as a function of the angular velocity signals, thereby stabilizing the image projected on the displaying surface with respect to undesired movements of the pico-projector device.
