This paper proposes a novel content-aware method for automatic focusing of the
scene on a 3D display. The method addresses a common problem that visualized
content is often out of focus, which adversely affects perceived 3D content. The
method outperforms existing focusing method, having the error lower by almost
30\%. The existing and novel focusing is extended with depth-of-field enhancement
of the scene to mitigate out-of-focus artifacts. The relation between the total
depth range of the scene and the visual quality of the result is discussed and
evaluated according to human perception experiments. A space warping method for
synthetic scenes is proposed to reduce out-of-focus artifacts while maintaining
the scene appearance. An user study was conducted to evaluate the proposed
methods and identify the crucial parameters in the scene-focusing process on the
3D stereoscopic display by Looking Glass Factory. The study confirmed the
efficiency of the proposals and discovered that the depth-of-field artifact
mitigation might not be suitable for all scenes despite theoretical hypotheses.
The overall proposal of this paper is a set of methods that can be used to
produce the best user experience with arbitrary scene displayed on a 3D display.
