Abstract
Fast processing of information represented in digital holograms is provided to facilitate converting a complex Fresnel hologram into a phase-only hologram, which can be a localized error diffusion and redistribution (LERDR) hologram, for displaying 3-D holographic images representative of a 3-D object scene. For a complex Fresnel hologram representing a 3-D object scene, a holographic generator component (HGC) can directly apply an LERDR process to the complex hologram to facilitate converting the complex hologram into an LERDR hologram. As part of the LERDR process, the HGC can partition the complex hologram into segments, convert the complex values of the pixels in each segment to phase-only values, and apply error diffusion to each segment to facilitate generating the phase-only hologram. The HGC can apply error redistribution to the last pixel of each segment to produce the resulting LERDR hologram, which can be displayed on a phase-only display device.
