1. A method of fabricating printed material for stereoscopic viewing, the method comprising: using a computer to implement the following steps: obtaining a first image of an object for a left eye for stereoscopic viewing; obtaining a first image of the object for a right eye for stereoscopic viewing; obtaining a second image of the object for the left eye by performing a first correction processing for removing perspective of an image at a first base surface in the first image of the object for the left eye, with respect to an area of the first image of the object for the left eye corresponding to the first base surface, and also performing a second correction processing for removing perspective of an image at a second base surface in the first image of the object for the left eye, with respect to an area of the first image of the object for the left eye corresponding to the second base surface, the second base surface having a predetermined angle with respect to the first base surface; obtaining a second image of the object for the right eye by performing the first correction processing for removing perspective of an image at the first base surface in the first image of the object for the right eye, with respect to an area of the first image of the object for the right eye corresponding to the first base surface, and also performing the second correction processing for removing perspective of an image at the second base surface in the first image of the object for the right eye, with respect to an area of the first image of the object for the right eye corresponding to the second base surface; and fabricating printed material for stereoscopic viewing based on the second image of the object for the left eye and the second image of the object for the right eye.
