The right movable screen 36 and the left stationary screen 37 each contain matrix elements according to the frame resolution of 1920000 pixels / 1600 × 1200 /. Each matrix element forms its pixel with three radiating cells emitting the basic colors R, G, B. The general view of the matrix element in Fig. 11 and includes an opaque body 56 of the corresponding shape, combining the three radiating cells 57, 58, 59. The lower left cell 57 emits red R color, top 58 emits green G color, bottom right 59 emits blue B color. Each emitting cell contains / Fig. 11/ in the front end of the housing 56 a micro lens 60, which acts as a micro lens, in the output end of the housing 56 there is a color filter 61 of one of the colors R, G, B, between the micro lens 60 and the color filter 61 there is a diaphragm 62, having a cylindrical body 63 with eight corresponding slots, in which are located neutral microfilter 64 _1-8 , respectively attached to their micropiezoelectric elements 65 _1-8 . The first ends of the micropiezoelectric elements 65 with two control inputs are rigidly fixed in the housing of the diaphragm 63, to the second free ends of the micropiezoelectric elements 65 are attached neutral microfilter 64, which in the absence of control pulses from the blocks 35/3 / pulse amplifiers completely block the radiation flux from the microlens 60 / fig .12, 13 /.

The radiation from the sources of irradiation / backlight / superbright white LEDs with the microlens 60 is directed through neutral microsilter filters 64 _1-8 to the color filter 61 (Fig. 12, 13), which imparts a color to the radiation. The inputs of the micropiezoelectric elements 65 _1-8 are the control inputs of the matrix element and are connected to the outputs of the corresponding pulse amplifiers in blocks 35/3 /. In the absence of control pulses / signals of code units / micropiezoelectric elements are in an unstressed state, all microfilter filters 64 are located along the optical axis of the microlens and one after another, the radiation flux is completely blocked. Upon receipt of a control pulse from a pulse amplifier to a micropiezoelectric element 65, its free end bends and removes its neutral microfilter 64 from the radiation flux for 40 ms / duration of the frame period / so that it does not overlap the flow, which corresponds to a unit in the code discharge, a neutral microfilter not extracted from the flow corresponds to zero in the discharge. When the code 11111111 arrives from the stream, all neutral microfilter 64 _1-8 are removed from the stream, and the maximum radiation comes from the cell. Upon receipt of different codes from the stream, neutral micro-filters 64, corresponding to units in the bits of the code, are output for 40 ms. As micropiezoelectric elements 65, tubular piezoelectric elements working in bending are used, which are strong and reliable during long-term operation [5, p. 27]. Cell elements are made as miniature as possible to obtain matrices up to 1 × 1 mm in size. The radiating cells are manufactured separately, combined into a housing 56 / Fig. 11/, and flat panel screens 36, 37 are drawn from the matrix elements. The radiating cells perform a code-to-radiation-radiation conversion. The radiation of three cells forms a pixel with brightness and color tone, respectively, of the three codes R, G, B. Due to the small size of the cells, each cell is not equipped with its own LED. Microlenses are irradiated with white LEDs located in an appropriate amount and in order on the back of the screen housings 36, 37 so that each LED irradiates several matrix elements, which will reduce the energy consumption of the screens. A frequency synthesizer 18 generates / Fig. 1/ from the first output pulses of 48 MHz sampling of video signals to the signal input of the key 19, to the second control input of the drive 24 of digital information and to the control inputs of the ADC 12-17, from the second output - pulses of 25 Hz of the stereo pair frequency control inputs of the keys 19, 20, to the first control input of the video detector 21 and to the input of the SA switch, from the third output, sampling pulses of 60 kHz of audio signals to the control inputs of the ADC 22, 23, from the fourth output, pulse frequency of 30 kHz lines to the signal input of the key 20 and on t swarm input of the video detector 21. FEP 1 with FZI 3 and 8 matrices generates analog video signals of the right and left frames, which the ADCs 12-17 convert to 8-bit codes that are received in parallel to the inputs of channels 27-32 of the recording of frame codes in the digital information storage device 24 / figure 2 /. Channels 27-32 work identically. When shooting and recording, the SA switch is set to position 1 / Fig. 1/, and 25 Hz pulses are fed to the first control input of the digital information storage device 24, from which they are fed in parallel to the first control inputs of six channels 27-32 of recording frame codes, and them to the information input of the distributor of 40 pulses / 4 /. The second control inputs of channels 27-32 receive 48 MHz sampling pulses, from which they are fed to the second control inputs of all drives 41 frame codes (Fig. 4/). Codes of video signals from the ADC 12-17 in parallel are fed to the information inputs of channels 27-32, and in them to the first to eighth information inputs of drives 41 _1-90000 frame codes.

Operation of drives 41 frame codes / Fig. 4/

The accumulation of frame codes is performed sequentially by drives 41 frame codes from the first to the 90,000th. Drive 41 _{1 is} filled first with codes of the first frame: the first pulse of 25 Hz arrives at the first control input U _{from /} Fig. 5/ and opens the first key 43 in block 42 _{1 of the} registers / Fig. 6/, the process of filling the first line of registers 46 into codes follows blocks 42 _1-1200 registers. After filling in the registers 46 in all blocks of 42 registers, the codes of the second line of registers 46 _1-8 should be filled in in block 42 ₂ , etc. to fill codes 1200-th row 42 last block ₁₂₀₀ registers. Upon filling in the codes of the drive 41 ₁ frame codes from the second output of the pulse distributor 40, a second pulse of 25 Hz follows, opening the key 43 / Fig.6/ in the second drive 41 ₂ of the frame codes, filling in the codes of the second frame period of blocks 42 _1-1200 in the registers. In the same order are filled with the codes of the following frame periods all of the following drives 41 _3-90000 frame codes. During the hour of shooting, 90,000 drives of 41 frame codes are filled. The capacity of one drive 41 frame codes is 1.92 MB. The capacity of the channel is 27 / 28-32 / frame code recording - 172.8 GB.

The filling of the registers 46 _{1-8 with} codes of the first line begins with the opening of the 25 Hz signal from block 40, the output 1 of the first key 43 in the first block 42 ₁ registers. The public key 43 passes 48 MHz pulses to the input of the pulse distributor 45, the clock pulses from which are supplied sequentially to the first / clock / bit inputs of the bits parallel to eight registers 46. The signals of the code bits from the corresponding ADC 12-17 are received to the third inputs of the bits of the registers 46 _1-8 . Upon filling 1600 bits of the registers from the last 1600th output of the pulse distributor 45, the signal U ₃ covers the key 43 and, as the control output signal, opens the key 43 in the next block _{2 of 2} registers, the registers of which are filled with the codes of the second line. For a period of 40 ms stereo pairs, registers 46 _{1-8 of} all blocks 42 _1-1200 are sequentially filled with row codes. On the last block 42 ₁₂₀₀ /fig.7/ control output applied in parallel to the fourth control inputs of all the blocks of registers 42 and converts them into the second switch 44 in an open state for passing a signal U _vyd codes from registers 46 _1-8 playback issuance. The capacity of one block of 42 registers is 1.6 KB.

Camcorder operation

For shooting and recording video information and sound, the SA switch is placed in position 1, the FDI matrices 3 and 8 will form the stereo pair analog video signals, the ADCs 12-17 will convert the analog video signals into 8-bit color codes R, G, B right and R ₂ , G ₂ , B ₂ left frames, which are received in parallel to the informational first-eighth inputs of channels 27-32 of recording frame codes. Sound codes from the ADC 22, 23 in parallel form are supplied to the first to sixteenth inputs of channels 33, 34 of recording sound codes. Codes of color signals and codes of two sound signals are recorded frame by frame in their drives 41 _1-90000 , 48 _1-90000 for an hour. When filling the last storage frame 41 ₉₀₀₀₀ codes output from block 42 /fig.7/ registers ₁₂₀₀ is supplied to the electromagnet on and off switch SA SA selector in neutral position. Before playing the video information, the viewer from the viewing point adjusts the field of view of the glasses 39 on the screens 36, 37. He puts on glasses, moving the right screen 36 in the frame 38, selects the distance between them so that each screen enters the field of view of his point. Fine adjustment of the visual fields is carried out by turning the glasses relative to each other and changing the length of their blends. For playback switch SA is put in position 2, 25 Hz pulses fed to the distributor 25 pulses cameras, from the outputs of which are fed in parallel to the third control inputs of the 3 U _vyd channels 27-32 and sequentially outputs of the drives 41 and _1-90000 frame sync codes from drives 48 _1-90000 sound codes frame codes and sound codes to the inputs of the block 36 _{1-6 /} 3 / pulse impulse amplifiers and the inputs of blocks 66 _{1-2 the} formation of analog sound signals. From blocks 35 _{1-6, the} amplified pulses of the codes are supplied to the control inputs of the emitting cells, forming on the screens 36, 37 the right and left frames of the stereo pair for a frame of 40 ms. The viewer sees the frames separately: with the right eye the right frame, with the left eye the left frame. At the end of playback, the output signal from the block 42 ₁₂₀₀ registers of the last drive 41 ₉₀₀₀₀ frame codes is fed to the electromagnet of the switch SA and turns it off to the neutral position: the playback of the recording ends, this is the end of the recording. Video information from channels 27-32 and sound from channels 33, 34 can be played repeatedly when the supply voltage in the camcorder is not turned off. When the power is turned off in the camcorder, the circuits of channels 27-32 and sound channels 33, 34 are de-energized and the information is eliminated. To save information, the user must rewrite it to the appropriate long-term medium before turning off the power of the camcorder. The inventive camcorder implements a method of two-screen playback of stereo video information, perceived by the viewer through the glasses of separate fields of view, which do not require complex manufacturing techniques and costs, doubled the resolution of the frames against the prototype and the number of LEDs involved in irradiation is reduced. Recording and playback is performed within an hour, increasing the duration of shooting and playing it can be doubled or more by increasing the drives 41 frame codes in channels 27-32 and the number of drives 48 code codes in the channels 33, 34.
