Two-tube color television camera

Claim 2

In a color video camera of the type employing a single color pick-up tube, the improvement comprising optical means receiving a light image of a scene and dividing it into two vertically aligned images, optical filters included in said optical means and causing the two resultant images to contain predominantly two different component colors of the scene, scanning control means for said pick-up tube causing the images to be scanned horizontally at a standard rate and causing the scan to alternate vertically between the two images after each horizontal scan as the scanning proceeds in a vertical direction.

Claim 3

A color video camera system comprising first and second pick-up tubes; an optical system including first means for directing one image of a scene onto said first tube; second means for directing two other images of the same scene aligned one above the other onto said second tube, and optical filters associated with said second means forming the two other images as different color images; scanning drive means operative to scan said tubes in synchronism and causing line sequential horizontal scanning of said two other images to produce a chroma output signal from said second tube which contains chroma information alternately from the two other images and to produce a luminance signal from said first tube, circuit means combining said signal from said second tube with an inversion of said luminance signal and producing a color composite signal, delay means receiving said color composite signal and operating to introduce a delay equal to one horizontal scan to produce a delayed composite signal, and means combining the color composite signal with the delayed composite signal and with the luminance signal to form a complete color video signal.

Claim 4

A color video camera system comprising first and second pick-up tubes; an optical system including first means for directing one image of a scene onto said first tube; second means for directing two other images of the same scene aligned one above the other onto said second tube, and optical filters associated with said second means forming the two other images as different color images; scanning drive means operative to scan said tubes in synchronism and causing line sequential horizontal scanning of said two other images to produce a chroma output signal from said second tube which contains chroma information alternately from the two other images and to produce a luminance signal from said first tube, circuit means combining said signal from said second tube with an inversion of said luminance signal and producing a color composite signal, delay means receiving said color composite signal and operating to introduce a delay equal to one horizontal scan to produce a delayed composite signal, and means combining the color composite signal with the delayed composite signal and with the luminance signal to form a complete color video signal.

Claim 5

A color video camera comprising an optical system and vidicon tube scanning means receiving three separate images of a scene from said optical system, one of said images being an essentially unmodified representation of the scene and the other two images being of different component colors in the scene and being arranged one above the other, said scanning means being constructed and arranged to scan said one image in a succession of lines and simultaneously and synchronously to scan said other component color images alternately in succession in line sequential fashion whereby a luminance signal is obtained for the full image and component cOlor signals are obtained for each of the component color images, processing means including a delay circuit receiving said color signals and providing corresponding direct color component signals and delayed color component signals lagging the direct signals by one scan line and combining the direct and delayed color component signals to produce a composite color output signal which is precisely registered to the scan of said one image.

Claim 6

A color video camera comprising an optical system and vidicon tube scanning means receiving three separate images of a scene from said optical system, one of said images being an essentially unmodified representation of the scene and the other two images being of different component colors in the scene and being arranged one above the other, said scanning means being constructed and arranged to scan said one image in a succession of lines and simultaneously and synchronously to scan said other component color images alternately in succession in line sequential fashion whereby a luminance signal is obtained for the full image and component cOlor signals are obtained for each of the component color images, processing means including a delay circuit receiving said color signals and providing corresponding direct color component signals and delayed color component signals lagging the direct signals by one scan line and combining the direct and delayed color component signals to produce a composite color output signal which is precisely registered to the scan of said one image.

Claim 7

A color video camera comprising an optical system and two pick-up tube scanning means receiving three separate images of a scene from said optical system, one of said images being an essentially unmodified representation of the scene on one of said tubes and the other two images being of different component colors in the scene and being aligned vertically of one another on the other pick-up tube, said pick-up tubes each having horizontal and vertical deflection controls for scanning the images, horizontal scan drive means connected to drive the horizontal deflection control of each of said pick-up tubes simultaneously and in phase, vertical scan drive means connected to drive the vertical deflection control of each of said tubes simultaneously and including a superimposed deflection signal arranged to cause alternation of the scan on said other pick-up tube between the two images on a line sequential basis, scanning means being constructed and arranged to scan said one image in a succession of lines and simultaneously and synchronously to scan said other component color images alternately in succession in line sequential fashion whereby a luminance signal is obtained for the full image and component color signals are obtained for each of the component color images, processing means including a delay circuit receiving color signals from said other pick-up tube and providing corresponding direct color component signals and delayed color component signals lagging the direct signals by one scan line and combining the direct and delayed color component signals to produce a composite color output signal which is precisely registered to the scan of the one image on said one pick-up tube.

Claim 8

A color video camera comprising an optical system and two pick-up tube scanning means receiving three separate images of a scene from said optical system, one of said images being an essentially unmodified representation of the scene on one of said tubes and the other two images being of different component colors in the scene and being aligned vertically of one another on the other pick-up tube, said pick-up tubes each having horizontal and vertical deflection controls for scanning the images, horizontal scan drive means connected to drive the horizontal deflection control of each of said pick-up tubes simultaneously and in phase, vertical scan drive means connected to drive the vertical deflection control of each of said tubes simultaneously and including a superimposed deflection signal arranged to cause alternation of the scan on said other pick-up tube between the two images on a line sequential basis, scanning means being constructed and arranged to scan said one image in a succession of lines and simultaneously and synchronously to scan said other component color images alternately in succession in line sequential fashion whereby a luminance signal is obtained for the full image and component color signals are obtained for each of the component color images, processing means including a delay circuit receiving color signals from said other pick-up tube and providing corresponding direct color component signals and delayed color component signals lagging the direct signals by one scan line and combining the direct and delayed color component signals to produce a composite color output signal which is precisely registered to the scan of the one image on said one pick-up tube.
