Abstract
A scanning projection system includes a scanning mirror module, a controlling circuit, and a laser module. A swinging motion of the scanning mirror module is controlled according to a driving signal, and a combined laser beam reflected by the scanning mirror module is swept across a projection surface to produce plural projection points on a projection surface. The controlling circuit includes a weight mapping unit for converting an image signal into a compensated image signal according to a position-and-weight mapping relationship. The laser module generates the combined laser beam according to the compensated image signal. After plural weights of the corresponding projection points are acquired according to positions of the corresponding projection points and the position-and-weight mapping relationship, the weight mapping unit multiplies the image signal by the corresponding weights according to the positions of the projection points. Consequently, the compensated image signal is generated.
