Abstract

A method for manipulating a laser projection device is provided. A laser projection device comprising a laser source, a driving module and a scanning mirror module is provided. The laser source provides a laser beam. The scanning mirror module disposed at one side of the laser source reflects the laser beam, so that the laser beam performs a scanning motion to form a projection track on a projection region. According to a projection distance, the driving module provides a first drive signal to modulate the number of scanning times of the scanning mirror module and provides a second drive signal to control the on/off time of the laser source to adjust an initial image resolution to a corresponding image resolution lower than the initial image resolution to maintain the frame quality of laser projection. The projection distance is a distance between the laser source and the projection region.
