Abstract

In video systems, the introduction of 3D video might be the next revolution after the introduction of color. Nowadays multiview autostereoscopic displays are in development. Such displays offer various views at the same time and the image content observed by the viewer depends upon his position with respect to the screen. His left eye receives a signal that is different from what his right eye gets; this gives, provided the signals have been properly processed, the impression of depth. The various views produced on the display differ with respect to their associated camera positions. A possible video format that is suited for rendering from different camera positions is the usual 2D format enriched with a depth related channel, e.g. for each pixel in the video not only its color is given, but also e.g. its distance to a camera. In this paper we provide a theoretical framework for the parallactic transformations which relates captured and observed depths to screen and image disparities. Moreover we present an efficient real time rendering algorithm that uses forward mapping to reduce aliasing artefacts and that deals properly with occlusions. For improved perceived resolution, we take the relative position of the color subpixels and the optics of the lenticular screen into account. Sophisticated filtering techniques results in high quality images.
