Telephoto sensor trigger in a solid state motion analysis system

Claim 2

A solid state motion analysis system comprising: solid state imager means for capturing an image of a scene, and for producing an image frame signal, wherein said imager means is selectively operable at different image frame rates up to several hundred frames per second; telephoto sensor means, for passively, noninvasively sensing a change in a changeable characteristic of said scene wherein said telephoto sensor means includes a telephoto lens and a photosensor optically coupled to said telephoto lens, such that said telephoto lens produces an optical image of a scene which is focused on said photosensor; wherein said telephoto sensor means is separate from said imager means and independently locatable relative thereto at a substantial distance therefrom; means for producing a trigger signal in response to a change in scene characteristic sensed by said photosensor of said telephoto sensor means; and solid state memory means for storing a plurality of image frame signals produced by said imager means, wherein an alteration in the mode of operation of said memory means is effected in response to said trigger signal.

Claim 3

The solid state motion analysis system of claim 1 wherein said telephoto sensor means is located to sense a changeable characteristic of a different scene than is captured by said imager means.

Claim 4

The system of claim 1 wherein said memory means is operating in a circular buffer mode and wherein said trigger signal stops the storage of image frame signals in said memory means.

Claim 5

The motion analysis system of claim 1 wherein said memory means is stopped and wherein said trigger signal starts storage of image frame signals in said memory means.

Claim 6

The system of claim 1 wherein said telephoto sensor means senses a change in scene brightness.

Claim 7

A solid state motion analysis system comprising: solid state imager means having a plurality of photosites arranged in an array of rows and columns for capturing an imager of a scene, and for producing an imager frame signal by reading out blocks of parallel subsets of photosites; wherein said image frame signal includes sequential blocks of video information, wherein each block of video information includes parallel lines of video signals and wherein said imager means is selectively operable at different imager frame rates up to several hundred frames per second; telephoto sensor means for passively, noninvasively sensing a change in a changeable scene characteristic wherein said telephoto sensor means includes a telephoto lens and a photosensor optically coupled to said telephoto lens, such that said telephoto lens produces an optical image of a scene which is focused on said photosensor; wherein said telephoto sensor means is separate from said imager means and independently locatable relative thereto at a substantial distance therefrom; means for producing a trigger signal in response to a change in scene characteristic sensed by said photosensor of said telephoto sensor means; and solid state memory means for storing a plurality of image frame signals produced by said imager means, wherein an alteration in the mode of operation of said memory means is effected in response to said trigger signal.

Claim 8

A solid state motion analysis system comprising: solid state imager means having a plurality of photosites arranged in an array of rows and columns for capturing an imager of a scene, and for producing an imager frame signal by reading out blocks of parallel subsets of photosites; wherein said image frame signal includes sequential blocks of video information, wherein each block of video information includes parallel lines of video signals and wherein said imager means is selectively operable at different imager frame rates up to several hundred frames per second; telephoto sensor means for passively, noninvasively sensing a change in a changeable scene characteristic wherein said telephoto sensor means includes a telephoto lens and a photosensor optically coupled to said telephoto lens, such that said telephoto lens produces an optical image of a scene which is focused on said photosensor; wherein said telephoto sensor means is separate from said imager means and independently locatable relative thereto at a substantial distance therefrom; means for producing a trigger signal in response to a change in scene characteristic sensed by said photosensor of said telephoto sensor means; and solid state memory means for storing a plurality of image frame signals produced by said imager means, wherein an alteration in the mode of operation of said memory means is effected in response to said trigger signal.

Claim 9

The system of claim 1 wherein said solid state imager means is selectively operable at frame rates up to at least a few hundred frames per second.

Claim 10

The system of claim 1, wherein said solid state imager means is selectively operable at frame rates up to at least 1,000 frames per second.

Claim 11

The system of claim 6 wherein said solid state imager means is selectively operable at frame rates up to at least a few hundred frames per second.

Claim 12

The system of claim 6 wherein said solid state imager means is selectively operable at frame rates up to at least 1,000 frames per second.

Claim 13

The solid state motion analysis system of claim 1 wherein said telephoto sensor means senses a change in a scene different from the scene captured by said solid state imager means.

Claim 14

The solid state motion analysis system if claim 6 wherein said telephoto sensor means senses a change in a scene different from the scene captured by said solid state imager means.
