ABSTRACT:
A method and apparatus are provided for unobtrusively estimating the characteristics of a projection surface, in order to correct the distortion of images resulting from the characteristics of the projection surface in the case of a projector. The method includes projecting at least one reference pixel and at least one counterbalance pixel corresponding to the reference pixel onto consecutive image frames, and correcting an image frame to be projected using correction information determined based on photographic information of the reference pixel.
