Integral Imaging is a method of recording full parallax 3D images which may offer an alternative to stereoscopic techniques, such as multi-view systems, for domestic 3D-TV. Previous understanding of integral images indicates that the required recording and display resolution is in excess of that available in current electronic imaging systems. This, in conjunction with the difficulty of manufacturing high quality micro-optical arrays has precluded wide spread research into integral imaging. An advanced form of Integral Image generation which has been previously described is re-examined with respect to new experimental evidence, which suggests that resolution requirements are far less stringent than currently believed. An outline of a possible integral-3DTV system is given. The novel application of existing compression schemes is described, which shows that the bandwidth requirements for Integral 3DTV are the same as for HDTV.
