Motion Parallax Holograms Generated from an Existing Hologram

Generating new motion parallax holograms is required for holographic head-mounted displays when the head moves. Additionally, it hologram generation from light field data that consist of a number images. However, re-rendering three-dimensional (3D) scenes and re-calculating are computationally complex. Therefore, we propose strategy with different an existing without 3D holograms. The proposed method employs Fourier band-pass filtering simple relation trigonometric functions, which makes capable skipping complex processes.
