We propose a system for visually-impaired people to see a common document without disturbing others when they see a piece of paper together. The system captures the image of a document by a camera and finds the document region in the image. Next, it determines transformation matrix between the object and camera coordinate systems based on the assumption of a rectangular document. Finally the system presents a rectified document image on the display of a portable computer. The result of subjective evaluation by human is that for more than 80% of the samples, the rectified images are easier to see than the input image.
