Abstract: A scanning projector and a method for operating a scanning projector including a light source module including a plurality of color light sources including at least one color light source provided in a plurality, and a scanner configured to execute scanning in the horizontal direction and the vertical direction using light beams emitted from the light source module. Light beams emitted from the plurality of same color light sources are projected on different positions on a screen within one frame and, thus, more rapid and effective scanning may be executed and a high-quality image may be formed.
