Visual perceptual-based film-type patterned retarder three-dimensional image representation

Film-type patterned retarder (FPR) three-dimensional (3D) displays differ from two-dimensional (2D) displays with respect to two distinct features: (1) vertical subsampling caused by a film circularly polarized on a display and (2) luminance loss caused by 3D glasses. To reveal the negative effects of these differences, we analyze the spectrum of an image on an FPR 3D display and investigate the contrast sensitivity of human vision for that image. Based on the analysis results, a preprocessing method is proposed for the aliasing problem caused by the vertical subsampling. In addition, because contrast sensitivity decreases with decreasing luminance, we propose sharpness compensation based on Barten’s contrast sensitivity function model. The proposed method performs more effectively than other methods in terms of 3D image representation.
