Abstract: | The methods for obtaining a controlled magnification of three-dimensional (3-D) integral images are usually based on the increase of the spatial ray-sampling rate of elemental image arrays. This is usually done by use of the moving array-lenslet technique. The major drawback of this technique is the alignment complexity due to the small lenslet movement. In this paper, we are proposing a digital magnification method that uses interpolation principles to increase the spatial ray sampling rate of elemental image arrays without lenslet movement in the pickup procedure. We compare the reconstructed 3-D integral images obtained when using the optical or the digital magnification methods, and show that the quality of both reconstructed 3-D integral images is the same. |
