It is convert to document papers or books into digital image data using a camera. The image shows the inclined target and wasted background regions as the image is not obtained carefully from the front. In order to strip off discarded area and to clarify information on the target area, the projection transformation is utilized to the target segment. This method, however, presuppose that the target is on the planar surface, so when the target is on the curved surface, distorted image is generated. Therefore we propose the method to estimate the target curve surface, and to expand planar surface suitable for the projection transformation.
