A plurality of original images of a subject viewed from different viewpoints are acquired. The first data circuit board has a portion of a plurality of conductors that are coupled to the display panel. The partitioning is performed in a series of stages by identifying one true cluster at each stage, and removing the nodes belonging to each identified true cluster from further consideration so that the remaining, unclustered nodes may then be grouped. The object lens focuses the real image onto a collinear holographic storage medium and thus produces a diffraction signal. The two larger ring arcs are used to form the retainer and guide ring. By using a normal dispersion HNLF in place of a zero dispersion HNLF, which configures the conventional CPF, it becomes able to overcome the above mentioned subjects.
