Preprocessor for Full Parallax Light Field Compression
First Claim
1. A preprocessor for a light field display system that provides full parallax, compressed, three dimensional processing of light field input data, the preprocessor comprising:
- a data receiver that receives light field input data in a data space;
a display configuration receiver that receives configuration information for the light field display system; and
a display space converter that converts the data space of the light field input data responsive to the configuration information for the light field display system.

Abstract
Preprocessing of the light field input data for full parallax compressed light field 3D display systems is described. The described light field input data preprocessing can be utilized to format or extract information from input data, which can then be used by the light field compression system to further enhance the compression performance, reduce processing requirements, achieve real-time performance and reduce power consumption. This light field input data preprocessing performs a high-level 3D scene analysis and extracts data properties to be used by the light field compression system at different stages. As a result, rendering of redundant data is avoided while at the same rendering quality is improved.
