is separated into visible and infrared components and directed to
the corresponding visible light camera and the infrared light
camera units (specification, paragraph bridging pages 2-3). The
adjustment of focusing of the infrared light image is achieved by
axially moving the infrared light camera so as to adjust its
focusing (specification, page 3). An understanding of the
invention can be derived from a reading of exemplary independent
claim 1, which is reproduced bellow:
1. A visible/infrared virtual studio imaging camera
comprising a zoom lens system; lightwave separating means for
separating light transmitted through said zoom lens system into
visible and infrared light components and emitting thus separated
light components; a visible light camera unit, disposed
downstream of said lightwave separating means for emitting said
visible light component, for capturing a visible light image
formed by said visible light component emitted from said
lightwave separating means; and an infrared light camera unit,
disposed downstream of said lightwave separating means for
emitting said infrared light component, for capturing an infrared
light image formed by said infrared light component emitted from
said lightwave separating means;
said visible/infrared imaging camera further comprising
moving/supporting means for supporting said infrared light camera
unit such that said infrared light camera unit is movable axially
of said infrared light component emitted from said lightwave
separating means, said moving/supporting means moving said
infrared light camera unit so as to adjust focusing of said
infrared light image; and
wherein information about distance from the virtual studio
camera to an object is obtained from the captured infrared light
image.
