It is widely known among photographers that the size of a room is exaggerated in an image taken using a wide-angle lens; such pictures are commonly found in hotel-reservation web sites. The present paper points out that the size exaggeration is a kind of optical illusion caused by an inappropriate viewpoint from which the image is seen, and develops a method for removing the illusion and thus recovering the true appearance of the room. This method requires only a single imae together with the lens center at which the image is taken. From those data, we can generate images that would be obtained if we stand at the same point as the camera and see around the original scene, changing the view direction. The validity of the method is shown by examples. Possible applications to size-exaggerated images posted in web sites are also discussed. |
