    Makoto Okui
    Science and Technical Research Laboratories, NHK Japan Broadcasting Corporation, Tokyo
    Appl Opt 44:4475-83. 2005
    ..We describe a way to design these filters with moire's residual energy and video signal energy as indices and demonstrate the validity of the model, which combines two filters to reduce moire fringes...
  2. ncbi request reprint Optical screen for direct projection of integral imaging
    Makoto Okui
    Science and Technical Research Laboratories, NHK Japan Broadcasting Corporation, Tokyo, Japan
    Appl Opt 45:9132-9. 2006
    ..The projector itself does not need an additional optical system. We report on the results of an experiment carried out to confirm the validity of the proposed method...

    J Opt Soc Am A Opt Image Sci Vis 21:951-8. 2004
    ..As a result, it is shown that a 3-D image is separated by local positional errors and blurred by global positional errors. In both local and global positional errors, 3-D images reconstructed far from the lens array are greatly affected...

    Jun Arai
    Science and Technology Research Laboratories, NHK Japan Broadcasting Corporation, 1 10 11 Kinuta, Setagaya, Tokyo 1578510, Japan
    Opt Express 21:3474-85. 2013
    ..We confirmed that the application of the pixel-offset method to integral 3D television is effective in increasing the resolution of reconstructed images...
