1. A method for manipulating a laser projection device, comprising:
providing a laser projection device comprising a laser source, a driving module and a scanning mirror module, wherein the scanning mirror module is disposed at one side of the laser source, and the laser source provides a laser beam; swaying the scanning mirror module to reflect the laser beam, so that the laser beam performs a scanning motion to form a projection track on a projection region; using the driving module, according to a projection distance, to provide a first drive signal to modulate the number of scanning times of the scanning mirror module and provide 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, wherein the projection distance is a distance between the laser source and the projection region, and the corresponding image resolution is lower than the initial image resolution. |
