Description
Summary:Image presentation using a projector requires a white screen. As the presentation with a projector becomes popular, image projection on any surface has been desired increasingly. To project images on any surface without giving viewers annoyance, the radiometric compensation is needed. This study focuses on the transfer function of the projector and on the distribution map of color on the projected surface. By using only raw digital images, we easily obtain those function and map. The radiometric compensation based on those function and map is applied to the input images. Results of the compensation are examined on a real indoor wall with patterns.
