Abstract
Abstract A television camera is used to scan a visual presentation of optically perceivable data in the form of lines of light under the control of a digital computer. A converter, responsive to the camera output, integrates the output signal over any selected television scan line, and generates a digital output representative of the scanned data. This data is then processed by the digital computer which also controls the camera scan.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
190 words
An automatic data acquisition system comprising: electro-optical means for scanning optically perceivable data and providing therefrom an electrical signal; conversion means responsive to said electro-optical means that generates as an output signal the integral of said electrooptical signal; programmed computing means for receiving the output of said conversion means and processing said output in a predetermined manner, said computing means generating an output signal that varies as said perceivable data varies; means responsive to said computing means for controlling the scanning by said electro-optical means; said electro-optical means comprising an electronic camera tube having an electron beam therein; means for deflecting said electron beam along a first axis; blanking pulse means responsive to said first axis deflection means for producing an output signal between selected degrees of deflection of said electron beam; said conversion means including control means responsive to said blanking pulse means, a first switching means responsive to said control means and interposed between said electronic integration means and the input to said conversion means from said electro-optical means, said control means opening said first switch means for the duration of said output from said blanking pulse means.
Claim 2
Dependent Claim
190 words
An automatic data acquisition system comprising: electro-optical means for scanning optically perceivable data and providing therefrom an electrical signal; conversion means responsive to said electro-optical means that generates as an output signal the integral of said electrooptical signal; programmed computing means for receiving the output of said conversion means and processing said output in a predetermined manner, said computing means generating an output signal that varies as said perceivable data varies; means responsive to said computing means for controlling the scanning by said electro-optical means; said electro-optical means comprising an electronic camera tube having an electron beam therein; means for deflecting said electron beam along a first axis; blanking pulse means responsive to said first axis deflection means for producing an output signal between selected degrees of deflection of said electron beam; said conversion means including control means responsive to said blanking pulse means, a first switching means responsive to said control means and interposed between said electronic integration means and the input to said conversion means from said electro-optical means, said control means opening said first switch means for the duration of said output from said blanking pulse means.
Claim 3
Dependent Claim
47 words
The system of claim 1 including a second switching means responsive to said control means interposed between said electronic integration means and a sampling and storing means, said control means closing said second switching means during a firs portion of said output of said blanking pulse means.
Claim 4
Dependent Claim
35 words
The system of claim 2 including resetting means responsive to said control means for resetting said electronic integration means to an initial condition during the remaining portion of said output of said blanking pulse means.
