First Claim
1. Apparatus for viewing a target volume and for providing a reaction consequent on a changing image therein comprising,(a) two means for viewing the target volume at spaced apart locations and for creating respective two dimensional video picture frame signals of the target volume which collectively define said target volume,(b) analyzing means for analyzing the signals relating to at least one discrete area within each respective picture frame, said analyzing means having feeding means for feeding control signals generated therein to a reaction providing means, said control signals being generated during a respective single frame of each respective picture frame, to provide said reaction consequent on there being an image change in the at least one discrete area from an earlier frame.

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.

5. A method for providing a reaction based on a changing image in a target volume under view, said method comprising:
-
(a) viewing said target volume at two spaced apart locations and creating respective two dimensional video picture frame signals the target volume; (b) analyzing the signals relating to at least one discrete area within each picture frame; (c) feeding control signals to a reaction providing means to provide a reaction in said reaction providing means consequent on there being an image change analyzed in step (b). - View Dependent Claims (6, 7, 8, 9)
