Abstract
Abstract Apparatus for viewing a target area and for providing a reaction consequent on a changing image in the target area (1), said apparatus having video cameras (3) for viewing the target area (1) and for creating video picture frame signal of the target area, analog to digital converters (7, 9, 11, 13, 14, 15, 17, 21, 31) for analyzing the signals relating to one or more discrete areas within each picture frame, the converters feeding control signals to a synthesizer to provide a change in the reaction consequent on there being an image change in the one or more discrete areas from an earlier frame.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
Apparatus for viewing a target area and for providing a reaction consequent on a changing image in the target area, said apparatus comprising (a) means for viewing the target area and for creating video picture frame signals of the target area; and (b) analyzing means for analyzing the signals relating to more than one discrete area within each picture frame, said analyzing means having feeding means for feeding control signals to a reaction providing means responsive to collective control signals generated during a single frame, to provide a change in said reaction consequent on there being an image change in the one or more discrete areas from an earlier frame, said analyzing means being dynamically alterable so that said discrete areas can be changed automatically to a succession of changing patterns over a plurality of successive picture frames consequent on there being a change occurring in the target area during a picture frame.
Claim 2
Dependent Claim
153 words
Apparatus for viewing a target area and for providing a reaction consequent on a changing image in the target area, said apparatus comprising (a) means for viewing the target area and for creating video picture frame signals of the target area; and (b) analyzing means for analyzing the signals relating to more than one discrete area within each picture frame, said analyzing means having feeding means for feeding control signals to a reaction providing means responsive to collective control signals generated during a single frame, to provide a change in said reaction consequent on there being an image change in the one or more discrete areas from an earlier frame, said analyzing means being dynamically alterable so that said discrete areas can be changed automatically to a succession of changing patterns over a plurality of successive picture frames consequent on there being a change occurring in the target area during a picture frame.
Claim 3
Dependent Claim
65 words
Apparatus as claimed in claim 1, wherein said analyzing means is constructed so that it can be programmed to cause said discrete areas to concentrate on an area in each picture frame where there is a change occurring from previous picture frames, whereby to provide said reaction based on a more detailed examination of the area where an image is changing in subsequent picture frames.
Claim 4
Dependent Claim
45 words
Apparatus as claimed in claim 2, wherein the analyzing means is programmable so that the number of discrete areas changes, consequent on there being a change in any one of the discrete areas in a picture frame, said change being in accordance with program instructions.
Claim 5
Dependent Claim
36 words
Apparatus as claimed in any one of claims 1 to 3, wherein the reaction providing means is a synthesizer and the apparatus is configured for playing music consequent on a changing image in the target area.
Claim 6
Independent Claim
129 words
A method for providing a reaction based on a changing image in a target area under view, said method comprising the steps of (a) viewing said target area n creating video picture frame signals of said target area; (b) analyzing the signals relating to one or more discrete areas 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); (d) causing said control signals to be generated in response to collective individual control signals generated for said one or more discrete areas; and (e) dynamically altering the discrete areas automatically if there is a change in the target area during one or more successive picture frames.
Claim 7
Independent Claim
129 words
A method for providing a reaction based on a changing image in a target area under view, said method comprising the steps of (a) viewing said target area n creating video picture frame signals of said target area; (b) analyzing the signals relating to one or more discrete areas 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); (d) causing said control signals to be generated in response to collective individual control signals generated for said one or more discrete areas; and (e) dynamically altering the discrete areas automatically if there is a change in the target area during one or more successive picture frames.
Claim 8
Dependent Claim
47 words
A method as claimed in claim 5, further comprising causing said discrete areas to concentrate on an area in each picture frame where there is a change occurring from previous picture frames, whereby to provide a more detailed examination of the area where an image change occurs.
Claim 9
Dependent Claim
35 words
A method as claimed in claim 6, further comprising causing the number of the discrete areas to change consequent on there being a change in any one of the discrete areas in a picture frame.
Claim 10
Independent Claim
21 words
A method as claimed in any one of claims 5 to 7, further comprising feeding said control signals to a synthesizer.
