Definitions

  • VHG VIDEO HOLOGRAPHIC GENERATION
  • ANGLED SQUARE LENS REFRACTION
  • This invention lies in the field of television signal generation and processing. More particularly, it concerns a system for generating and processing television signals from a visual scene, in which a threedimensional effect can be observed in the displayed television signals, by properly orienting the optical axes of three camera tubes and by alternately muting the signals from a first and third tube which are adapted to pass the first and third primary colors.
  • the present invention relates to apparatus and process for generating television signals for viewing .and reproduction of three-dimensidonal holografic visual scenes without the use of special coded glasses, and is accomplished within the framework of the NAB and European and National television broadcast standards, without changing the basic principals and structure of the conventional TV receiver, comprises one or more conventional TV cameras, including one or more separate video camera tubes, (nominally three), each camera tube adapted to receive light of one of the three primary colors.
  • the camera tubes and lenses are aligned with one or more optical axes which are normally parallel and are spaced apart at a selected distance in a horizontal plane. At least one plane may be rotated so that it can be turned through a small angle in such a direction as to intersect the other axes at a selected distance in front of the camera.
  • Synchronizing beams are provided for two subrasters in scanning of the camera tubes.
  • injected control frequencies above and below horizontal line speed selectively mute or switch primary color signals generating a vertical (above line speed switching) and horizontal (below line speed switching) light sensitive color bar grid, which when counter spun against, by spinning parallel RGB (BGR) bars, generate holografic muting patterns.
  • BGR parallel RGB
  • a special square lens adapter redesigned in this embodiment intensifies the dimensional holografic effect.
  • a special laser lighting system reflected through the square lens and synchronized with the vertical and horizontal video camera sync scanning system will further process and intensify the three dimensional holografic visual scene, which is further processed for reproduction from tape to tape transfer, tape to film transfer, or transmitted in a normal fashion to conventional video carrier systems such as cable or satallite transmission.
  • the proces sed video signals are received and displayed on a conventional receiver the visual scene will be seen in three dimensional and holografic transmission.
  • the processed video signals are received and displayed on a conventional receiver the visual scene will be seen in three-dimensional and holografic viewing.
  • a means to dedicate during the selected delay period a language translation circuit color generated computer means which permits the viewer to select a language track of his choice, and an actual or simulated audio stereo tract. (FIGURE 50).
  • FIG. 49 Also shown and described in this disclosure is a laser flat screen projector (Fig. 49), which will more accurateldy display the holhyroid picture, and a holografic film camera. (FIGURE 48).
  • the human eyes perceives depth of field and stereografic information to the brain by the use of horizontal scanning of the optic nerves connected to the rods and cones of each eye through individual nerve bundles. That is the brain by use of it's optic nerve endings to the rods and cones of each eye scans one eye in a clockwise horizontal fashion while simultaneously scanning the opposite eye in a counter-clockwise horizontal fashion from the other side of the brain via way of it's respective nerve bundles. Thih phenomena can be observed by alternately holding a red filter in front of one eye and then the opposite eye, while viewing TV tuned to display noise or 'snow' displayed on the TV screen.
  • the video signals of a TV camera must be converted to allow R, G, B, color rotation, or phasing, of injected control frequencies that scan clockwise for a time frame, and counterclockwise during the second time frame or scan, thereby matching the physiological make-up of the brain's scanning as it horizontally scans the rods and cones of the human eye, in a clockwise fashion for one eye and counter-clockwise for the opposite eye.
  • the ability to polarize the first eye to one scan or time frame (sub-raster) of a TV display and simultaneously polarize the opposite or second eye to the second scan (sub-raster) or time frame of a TV display is accomplished in the following way. (1) By injecting control frequencies above line speed at approximately one Mgz.; vertically aligned color zones are encoded to a TV receiver which simulaltes the brain's ability to horizontally scan rods and cones of the human eye.
  • RGB color rotation By phasing the RGB color rotation during switching of injected control frequencies; vertically aligned color zones are RGB rotated or polarized during the first scan to correspond to the clockwise scanning of the first eye from red to blue, during the time frame or scan of the second sub-raster and the control frequencies are B rotated, or phased, in a counterclockwise direction from blue to red, which corresponds to the brain's ability to simultaneously distinguish primary colors while scanning the optic nerves of each eye horizontally in opposite directions.
  • the conventional television camera there are three video camera tubes, each one adapted to pass and process one of the three primary colors, such as, for example, red, green and blue.
  • the first camera tube C1 , number 42A processes the red light
  • camera tube C2 processes the green light
  • the third camera tube C3, 42C processes the blue light.
  • the lines 18A, 18B and 18C represent the three optical .axes. They are nominally parallel, and spaced apart a selected distance. When precisely parallel to each other, they will not transmit a three-dimensional signal.
  • FIGURE 1 two camera lenses are shown L1, numeral 20A and L3, numeral 20C, respectively, in the optical axes A1 and A3.
  • the dash lines 22 and 24 represent control means, which tie together the two lenses L1 and L3, so that as one is rotated the other one will be rotated and the focus of each of them will tracktogether and the zoom effect will also track.
  • the precise directions of the three axes are important only in the region of the lenses L1 and L3. After that the optical axis moves into the camera but the precise position of the video camera tubes can be altered by the use of mirrors, etc.

  • lens L1 passes red light to the first camera tube 42A, and part of the green light to the third video tubes C3 and some additional green light to the second videocamera tube 42B.
  • a camera control (58) is provided as is customary in the video camera, and no detail of this control is required since the conventional control can be used.
  • This camera control 58 provides a synchronizing buss 48 which provides signals to the video amplifiers and to the camera tubes to control the synchronization of the raster sweeps in all of the camera tubes and amplifier.
  • the camera control means 58 will provide two subscans interlaced, as in the conventional TV system.

  • the analog switch When there is positive signal on lead 52A, the analog switch will pass signals on the 46A through 56A to the camera control 58 in exactly the same way that the signal goes from video amplifier V2 through lead 46B to the camera control.
  • the switch 54A when there is no signal on lead 52A, the switch 54A will blink the transmission of signal from 46A to the camera control.
  • the flip-flop and the analog switches act as a synchronized switch, and other kinds of switches could be used, so that on the first raster the red signal and green signal are passed but no blue signal and on the second raster the green signal and blue signal are passed but no red signal.
  • the three video signals on leads 56A, 46B and 56C are then processed in the camera control to provide the transmitted signal 60 to the transmitter, and eventually to a television receiver.
  • the picture on the television receiver will look like any conventional picture in three colors and will be twodimensional.
  • a pair of eye glasses 97 are provided, in which one lens 98A is red-passing glass, and the lens 98C in the other part of the eye glass 97 is bluepassing glass, then the right and left eye will ultimately see the blue picture and the red picture which are not precisely aimed at the same scene and, therefore, will show a three-dimensional optical effect.

  • FIGURE (10) is a dual pulse phaser circuit which is phase pre-settable and capable of pulsing the quadrature 90 degree phased waveform of FIGURE (8) forward or backward for a selected time period which is also presettable both for the forward and reverse wave form rotation.
  • This circuit will be utilized in subsequent diagrams or figures of various embodiments of the invention herein described.
  • This switching circuit is synchroniz-ed to the TV camera from the camera sync generator outputs, horizontal sync (1), the 3.58 MHZ (2), and vertical drive (3).
  • the outputs of this module or circuit board P1(31) and P2 (32) will drive the transmission gates of the muting circuits of the camera circuits to be explained in later embodiments.
  • the 3.58 MHZ sync (2) from the camera control unit CCU comes to the module in the form of a sine wave (5).
  • This sine wave is converted to a positive pulse (11) by a dual 741 half wave re-ctifier circuit (8) which makes the signal capable or acceptable for the CMOS digital circuitry.
  • These clockpulses enter the clock input of a presettable up-down 0-16 counter (16).
  • This counter (16) is presettable by four binary on and off switches (13) which put a positive Vss voltage to the JAM inputs of the counter (16). This determines where the counter (16) will start counting, thereby determining the begining phase of the dual pulse generator.
  • the negative horizontal sync pulse (1) coming from the camera control unit to be described later is inverted by 741 inverter(7) to positive reset pulses (11) which enter the updown counter (16) via line (14) to the preset enable input of the countaer (16). This starts the counter at the predetermined number set by BCD JAM input switches (13).
  • flip-flop (18) controls or determines whether counter (16) counts up or down. If is a positive “one” then counter(16) will count up or forward. If of flip-flop (18) is negative ground potential is “zero” then counter (16) will count down or in reverse order from its presettable position (13), or phase over and over again until reversed by flip-flop (18). Conversely, counter (16) will count up or forward from its preset enable JAM input (13) BDC count. The counter (16) will continue to count 0-16, over and over again, until it is reversed. The output of this, counter is fed via ABCD bus lines(17) to the ABCD (binary numbers) input of the BDC (4) line to (16) line decoder (20).
  • This decoder converts the digital BDC binary count to a decimal 1 to 16 output where the counts of 0,4,8, and 12 are connected via lines (21), (22) to “or” gate (25) and lines (23) and (24) to “or” gate (26). At this point (on lines (27), and (28)) a quadrature count is generated.
  • flip-flops (29) and (30) are needed to produce the square wave ninety degree quadrature phased output of P1(31) and P2, (32), which serve as control pulses for the analog switcher or transmission gates of the primary color pulsed outputs of the subsequent camera embodiments.
  • Counter (38), daeccder (39), presettable switching matrix (47) and "or" gate (45) as preset in FIGURE 10 will cause the updown counter (6) to forward count two sub-rasters and reverse count three sub-rasters, long enough for a complete 1/60th of a second scan on the TV tube. This will enable the camera to do a 2, 3, sweep sub-raster sequence necessary for an unscrambled three-dimensional holografic NTSC tape to film transfer.
  • FIGURE 11 TRI-PULSE PHASER
  • the tri-pulse phaser circuit is described. It is similar to the dual pulse phaser of FIGURE 10, with the additional capacity of pulsing all three of the primary color video signals. However, in the described embodiments it may be used to pulse only the first and second primary color signals by not connecting P3 (37) and may be interchanged with the dual pulse phaser in FIGURE 10.
  • This tri-pulse phaser of FIGURE 11 also has the additional advantage of its own variable plus or minus one MHZ on board clock (5) which is synchronized by reset line (14A) to insure straight vertical lines of the resultant color sensitive zones described in FIGURE 8 and FIGURE 9.
  • THE TRI-pulse phaser also has a simplified film camera sync system comprising, of 0-4 counter (37), "or” gate (40), and flip-flop (45).
  • Switch (38) as shown connected to counter (37) routes vertical drive pulse (12) to the 0-4 counter (37) where the BDC outputs A(one) 41 and C(four)43 are connected to "or" gate (40) to generate an output pulse on the counts of 1,3 and 4, for a unified sync transfer which will work on both PAL and NTSC systems for dimensional holografic film transfer systems. It accomplishes this by sending a change of 1 to 0 pulse to up-down counter (16) in a 2, 2, 1 sequence.
  • FIGURE 9 What has been described is a tri-pulse module designed to produce the pulse train required to generate the waveform outputs and color phasing of electronic video signals as shown in FIGURE 9 which is essential to the process and method of three-dimensional holografy reproduction of a visual scene for viewing on television.

  • Fig. 44A2 is shown an improved version of the slightly varying dual syntheziser of Fig. 44A1. It was discovered during prototyping that the positive and negative culmultive effect of duty times fought each other when modulated together; actually components to short out. So a variable floating power supply network as shown in Fig. 51 was sesigned to make the left 19A , and right 19B portion of the dual syntheziser float reactively with respect to each other. So the 19A section is powered by the power supply #1 (9A of Fig. 51); the 19B sectionor right syntheziser is powered by power supply #2 (9B of Fig. 51). These power supply are adjusted so that the ouptputs 17A and 17B of dual synthesysers are equally centered at balance outputs summing to zero voltages by a DC meter reading.

  • wave shapper 1B is clocked at input 1, by the rightoutput (17B of Fig. 44A2) of said dual syntheziser of Fig. 44A2.
  • This will cause the horizontal rainbow encoded bar generati onoutput of the said square grid to vary in thickness toelle a slightly varying squeege effect of the thickness of said horizontal rainbow encoded light sensitive bar zones.
  • thephase of the square grid generated by the circuit of Fig. 44B4 is locked to the phase of the spinning bars created by the right side of the ouput of said dual syntheziser (17B of Fig. 44A2) is locked to the said horizontal rainbow encoded bars of the saidsquare grid.
  • Timing chart 16 also shows the relationship of the 0o, 120o, and 240° phased control of Red, Green and Blue switching.
  • Outputs of the 4018 Cmos chip 4 which on a 1 to 6 count generati onwired to exit a new pulse every 2 counts phased 120 apart and lasting for approximately 3 counts to give a continuously over-lapping rainbow encoded color encoded generated light sensitive barzone pattern.
  • the 3rd power supply output (9C of Fig. 51) powers the components of Fig. 44B4; thus the circuitry of 44B4 and the left and rightsides (19A and 19B of Fig. 44A2). are symetrically suspended or floated reactively to each other.
  • Fig. 50 is shown a final improved embodiment of the combination of circuitry of Figures 44A2 and 44B2 with symetrical suspended reactively floated tri-power supply of Fig. 51.
  • This embodiment as shown in Figure 50 shows the above- and below- variable slightly fluctuating subcarrier speed phased outputs so the said dual synthesizer 2 (17A and 17B of Figure 44A2) via lines 14 and 15 are routed through transmission gates 11 and 12 via lines 16 and 17 to magnetic induction coils 4 and 47 pf capacitors 6 to output a composite video signal with dual spinning bar encoding, via lines 9 and 8 clocking the square grid rainbow color-encoded circuitry of 44B4, phased fluctuating spinning of the square grid is attained.
  • the resulting modulated encoded composite video envelope contains the rainbow encoded dual spinning bars and fluctuating spinning square grid to produce the video muting holographic generation of video images.
  • Outputs 11, 12 and 13 are optional discrete switching in and out connections for the muting of the RGB of a camera or television switcher board, video games, or any discrete RGB video display monitor.
  • FIG 51 is shown a variable multiple floating power supply which is powered by a +12 volt d.c. power rail and a -12 volt d.c. power rail, 2.
  • three separate floating continuously adjustable power supplies, 9A, 9B and 9C, are shown (as many as required may by cascaded).
  • Each power supply may be adjusted from 0% to 100% of the plus rail to minus rail voltages (in this case, a 24 volt swing from -12 volts to +12 volts), or a total of 24 volts rail-to-rail swing without accidently reversing polarity.
  • the positive output of power supply #1 (9A) may be independently adjusted from 0 to 12 volts by 5k potentiometer 3, but the positive output 3B can never be adjusted to less then half of the rail-to-rail plus and minus voltage swings, thus eliminating any danger of accidently reversing the polarity of the power supply output 9A, because of the voltage dividing effect of inline 5K resistor 3A which prevents the adjustment of 5k pot 3 from adjusting the below ground potential of the plus and minus power rails 1 and 2.
  • the voltage range adjustment of pot 3 for the plus leg of 3B power supply #1 (9A) is limited to a 0 to +12 volt range only.
  • the negative swing or adjustment of the negative output 4B of power supply #1 (A) may be adjusted by 5k pot 4A from 0 volts or ground potential of the plus and minus 12 volt supply rails 1 and 2, downwards to a 12 volt maximum, but cannot be adjusted above 0 volts or beyond ground potential of the plus and minus 12 volt power supply rails 1 and 2, because of the in-line 5k resistor 4 which divides the plus and minus 24 volt swing of the said power rails 1 and 2 in half. Therefore, the negative output of power supply # 1 (9A) may be adjusted to any voltage between 0 or ground potential downward to a minus 12 volts.
  • adjustable power supplies 9B and 9C are shown. The selection of 5k, 1/2 watt pots and resistors are in keeping with amperage requirements of a few chips. If more amperage is required, then lower ohm value and higher watt rated resistors should be selected (i.e., 2000 ohm, 1 watt resistors and pots).
  • power supply #1 (9A) and #2 (9B) may be used to adjust the depth of modulation into each of the two synthesizers of the dual slightly varying synthesizers of Figure 44A2 (i.e., for a 50% depth modulation, synthesizer 19A of Figure 44A2 can be powered by power supply #1 (9A) of Figure 51 at +4 volts on the positive output 3B as adjusted by pot 3; and at -2 volts by the negative output 4B as adjusted by pot 4A.
  • Synthesizer 19B of Figure 44A2 can b,e powered by power supply #2 (9B of Figure 51) at +2 volts on the positive 5B as adjusted by pot 5; and a -2 volts by the negative output 6B as adjusted by pot 6A.
  • VHG circuitry that is nominally shown to generate video holography (dimensional visual scenes) can also be used to present dimensional audio scenes. Both monaural and stereophonic sound reproduction is affected. In both cases (one speaker as in monaural sound reproduction, and two separated speakers (2) as in stereophonic audio reproduction) the sounds heard having been processed with AHG are perceived by the human hearing process spatially rearward and forward as well as left and right, and upward and downward sound placement reflecting acoustics of the original sound stage. Thus, the audio portion of the video envelope is simultaneously treated with the VHG circuit. Dynamic frequency range and signal-to-noise ratio are improved.

Abstract

Dans un procédé et appareil de génération holographique vidéo, des signaux vidéo d'une scène visuelle sont générés pour visionnement tridimensionnel et reproduction holographique à l'aide d'une ou plusieurs caméras conventionnelles (14). Des faisceaux de synchronisation sont prévus pour des sous-trames lors du balayage des tubes analyseurs. Pendant le balayage alterné des sous-trames, des fréquences injéctées de commande au-dessus de la vitesse des lignes horizontales bloquent ou commutent sélectivement des signaux de couleurs primaires qui génèrent des zones de couleur verticales sensibles à la lumière (filets). Le circuit peut être utilisé dans des caméras de génération vidéo ou dans des applications de réception de télévision de moniteurs vidéo. Dans un mode de réalisation, des zones de barres de forme d'onde (verticales) pivotent les unes par rapport aux autres dans le sens inverse du sens des aiguilles d'une montre pendant des cadrages temporels déphasés spécifiques, en générant ainsi une ou plusieurs images vidéo dimensionnelles. L'invention comprend également un système d'éclairage synchronisé à laser extérieur (15, 16 de la Fig. 44D) et un système de projection de télévision à laser. On montre une caméra holographique à pellicule mobile, et finalement l'amplificateur de signaux vidéo entièrement numérique.
