An image projecting device includes a synchronizing signal generating unit for generating first and second synchronizing control signals. A light source unit is operable so as to generate a plurality of light beams, each having a specific wavelength, and includes a plurality of light emitting diodes that are adapted to be controlled by multiple input signals so as to enable the light beams to have a respective intensity corresponding to a current projected one of multiple pixels of an image frame associated with the input signals. A reflecting unit is controlled by the first and second synchronizing control signals to reflect the light beams from the light source unit onto a corresponding coordinate on a screen for showing the current projected one of the pixels thereon.
