Abstract
The conical holographic stereogram is considered an interesting example for holographic display. To form a conical holographic stereogram, the 2D images are recorded on a series of slit holograms following a circle pattern. This procedure however, introduces some problems. It causes the reconstructed image be composed of an assembly of different image portions reconstructed from the slit holograms, and since the slit holograms are arranged in a conical structure, the reconstructed image is seen widened at the top and narrowed at the bottom. To cancel the distortion and correct the perspective view, an image processing is performed on the original set of images. By picking up pixel data of successive frames of the original set, a new set of 2D images is formed.
