Abstract: This invention discloses a projector system includes a memory, a projecting unit, an image reading unit and an image analysis unit. The memory stores LUTs corresponding to different background planes respectively. Each LUT is related to an HSI value, Hue, Saturation and Intensity, of a corresponding background plane. The projecting unit projects an image on a background plane. The image reading unit gathers a data of the background plane. The image analysis unit analyzes the data to find out an HSI value of the background plane. The image analysis unit searches the memory to find a corresponding LUT according to the HSI value of the background plane and amend the image projected on the background plane according to the corresponding LUT.
