ABSTRACT:
Apparatus is disclosed for viewing a target volume by two spaced apart viewing devices which create respective two dimensional video picture frame signals. The picture frame signals are divided into discrete areas. If there is an image change in one of the discrete areas then analyzing means provides control signals which feed a reaction providing means, which in turn is then responsive to a change of an object within the volume.
