Abstract
Abstract To increase resolution in a television system, a plurality of television cameras are positioned to view a common scene and to furnish video information to a common display tube which has a like plurality of electron gun systems and beam deflecting means to control each electron beam individually. Brightness is increased proportionately. Beam deflection voltages (or currents) in the display tube and in the cameras are synchronized but differ in amplitude and/or phase so that scanning lines associated with different cameras are interspaced on the display tube screen.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
254 words
In a television system the improvement comprising: a plurality of camera-pickup systems, a common display tube having a screen, a plurality of electron gun systems in said common display tube for generating a plurality of electron beams, a plurality of deflection means for causing each of said electron beams to scan across all of said screen, said deflection means including a separate independently controllable field deflection means located in said display tube for each respective electron gun in said display tube and at least one independently controllable line deflection means located in said display tube, connecting means whereby the video information developed by said cameras is forwarded to said display tube and presented on said screen, each camera being connected to a respective electron-gun system, wherein said deflection means in said tube are controlled by sweep voltages to deflect each of said plurality of electron beams in such manner that each beam scans in a respectively different part of said screen at any particular instant to thereby avoid interference, wherein said plurality of deflection means comprise a plurality of field sweep generators and a singleline sweep generator, and including a plurality of slope control generator means, one of said slope control generator means being connected to a control input of a respective one of said plurality of field sweep generators to control the voltage output of said field sweep generator to thereby compensate for any nonlinearities in said system and thereby avoid distortion of video information presented on the screen of said display tube.
Claim 2
Dependent Claim
254 words
In a television system the improvement comprising: a plurality of camera-pickup systems, a common display tube having a screen, a plurality of electron gun systems in said common display tube for generating a plurality of electron beams, a plurality of deflection means for causing each of said electron beams to scan across all of said screen, said deflection means including a separate independently controllable field deflection means located in said display tube for each respective electron gun in said display tube and at least one independently controllable line deflection means located in said display tube, connecting means whereby the video information developed by said cameras is forwarded to said display tube and presented on said screen, each camera being connected to a respective electron-gun system, wherein said deflection means in said tube are controlled by sweep voltages to deflect each of said plurality of electron beams in such manner that each beam scans in a respectively different part of said screen at any particular instant to thereby avoid interference, wherein said plurality of deflection means comprise a plurality of field sweep generators and a singleline sweep generator, and including a plurality of slope control generator means, one of said slope control generator means being connected to a control input of a respective one of said plurality of field sweep generators to control the voltage output of said field sweep generator to thereby compensate for any nonlinearities in said system and thereby avoid distortion of video information presented on the screen of said display tube.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein said deflection means are arranged to deflect said electron beams across said screen in an interspaced pattern of scanning paths.
Claim 4
Dependent Claim
32 words
The apparatus of claim 1, and including a separate field sweep generator and a separate associated slope control generator for each camera and for each field deflection means in said display tube.
Claim 5
Dependent Claim
58 words
The apparatus of claim 3, and including a separate line sweep generator and a separate associated slope control generator for each camera and for each line deflection means in said display tube, and a separate field sweep generator and a separate associated slope control generator for each camera and for each field deflection circuit in said display tube.
