ANALYSIS AND OPTIMIZATION OF PIXEL USAGE OF LIGHT-F IELD CONVERSION FROM MULTI-CAMERA SETUPS TO 3 D LIGHT-FIELD DISPLAYS Péter

Light-field (LF) 3D displays require vast amount of views representing the original scene when using pure lig ht-ray interpolation to convert multi-camera content to di splayspecific LF representation. Synthetic and real mult i-camera setups are both used to feed these displays with im age-based data, however the layout, number, frustum, and reso lution of these cameras are mostly suboptimal. Storage and transmission of LF data is an issue, especially con sidering that some of the captured / rendered pixels are lef t unused while generating the final image. LF displays can h ave significantly different requirements for camera set ups due to differences in Field of View (FOV), angular resolut ion and spatial resolution. An analysis of typical camera s etups and LF display setups, and the typical patterns in pixe l usage resulting from the combination of these setups are presented. Based on this analysis, an optimization method for virtual camera setups is proposed. As virtual cameras have wid range of adjustment possibilities, highly optimized setups for specific displays can be achieved.
