Abstract
The present invention provides a micro projector device including a MEMS mirror, a laser source module, a detection module, and a control unit. The MEMS mirror has a first portion and a second portion, the first portion pivots to the second portion, and the first portion oscillates in relation to the second portion. The laser source module generates a laser light to a reflection plane of the first portion of the MEMS mirror. The detection module detects a capacitance value between the first portion and the second portion. The control unit determines the relative position between the first portion and the second portion according to the capacitance value, and provides image data to the laser source module according to the relative position. The reflection plane of the first portion is configured to reflect the laser light from the laser source module to a projection plane.
