In the absence of control pulses / unit signals in the code / micropiezoelectric elements are in an unstressed state, all microfilter filters 65 are located along the optical axis of the microlens, the radiation flux is completely blocked. When a control pulse arrives at micropiezoelectric element 66, its free end bends and removes its neutral microfilter 65 from the radiation flux for 20 ms / 1 ms / duration of the frame period, so that it does not block the flow, which corresponds to a unit in the code discharge, the neutral microfilter is not removed from the flow corresponds to zero in the discharge. When a code arrives from 11111111 units alone, all neutral microfilter filters 65 _1-8 are removed from the stream, and the maximum radiation expires from the cell. Upon receipt of different codes from the radiation flux, they are output at 20 ms / 1 ms / neutral microfilter 65, corresponding to units in the bits of the code. As micro-piezoelectric elements 66 tubular piezoelectric elements are used, which work on bending, are strong and reliable during long-term operation [5 p.27]. Cell elements are made as miniature as possible to obtain matrix elements up to 2 × 2 mm in size. The emitting cells are manufactured separately, combined in the housing 57, and a flat panel screen is assembled from the matrix elements. Emitting cells perform the conversion “code - radiation brightness”. The radiation of three cells forms a pixel with brightness and color tone, respectively, of the three color codes R, G, B. The microlenses are irradiated with white LEDs located in the corresponding order and quantity inside the screen cases on the back side so that each LED irradiates several matrix elements to reduce power consumption screen. A frequency synthesizer 27 / Fig. 1/ generates 1 MHz pulses of sampling frequency from the first output to the input of the second key 26, which reads the video signals from the pixels of all lines in parallel in high-speed shooting mode 1000 frames per second, from the second output generates 1 kHz pulses to the control input U _from key 26 with a duration of 1 ms to open key 26 for the duration of the frame; from the third output, sampling pulses of sound codes 90 kHz; from the fourth, pulses of the frequency of stereo pairs 50 Hz, opening key 25 for a duration of 20 ms, and from the fifth output, pulses 50 kg the signal input of the key 25 operating readout video signal with pixel rows when shooting at a frequency of 50 Hz stereo.

Each block 12-17 contains the number of lines in the frame of 1000 ADCs, of which there are only 6000. Codes with ADCs are received in their drives 18-23 in parallel. The sequence of filling in the frame codes of the drives 42 frame codes (Fig. 3/) carries out pulses from the output of the distributor 41 pulses, the input of which receives pulses of 50 Hz / or 1 kHz / s of the synthesizer 27 frequencies. To play the video information, the switch 29 _{2 /} Fig. ₁ / is placed in position 1 / Fig. 1/, at which a recording with a frequency of 50 Hz is played, or in position 2, in which a recording with a frequency of stereo pairs of 1 kHz is played. During playback, codes of video signals and sound codes from drives 18-23 are output synchronously frame-by-frame to the playback device 24, where the pulses of the bits of the codes are amplified in amplitude and fed simultaneously to the control inputs of all the micro-piezoelectric elements of the emitting cells (Fig. 10/), which convert the codes to the corresponding brightness and color tone, pixels glowing on the screens. The viewer receives images from the screens through glasses of 40 separate fields of view: the right eye sees the image of the right screen, the left eye - the image of the left screen.

The operation of the drive 42 frame codes, Fig.3.

In each drive 42 frame codes / Fig. 4/ codes are received from a thousand ADCs in parallel with a thousand blocks of 43 _1-1000 registers. With the arrival of the leading edge of the frame pulse of 50 Hz / 1 kHz /, the first key 44 / Fig.5 / opens and the pulses U _{d of} sampling 50 kHz / 1 MHz / are received at the input of the pulse distributor 46, and the pulses U _{d are} sequentially output from the outputs of the pulse distributor 46 the first inputs of the bits are parallel to eight registers 47, the third information inputs of which receive codes from the corresponding ADC. Each block of 43 registers comes from a string of 1000 codes. With the end of the line, all registers 47 thousand blocks of 43 registers in the drive 42 ₁ frame codes are filled in parallel. For an hour of shooting at 50 Hz stereo pairs, all 180,000 drives of 42 frame codes / 3 / are filled. During high-speed shooting, drives 42 _1-180000 fill up 20 times faster, i.e. in just three minutes. The sequence of filling drives 42 frame codes is performed by pulses from the outputs of the distributor 41 pulses, the input of which receives pulses of stereo pairs of 50 Hz or 1 kHz. The capacity of one drive 42 frame codes is 1 MB, the capacity of the drive 18 / 19-23 / digital video information is 180,000 MB or 180 GB.

The sequence is performed by pulses from the outputs of the 48 pulse distributor, to the input of which the stereo frequency pulses arrive. With the arrival of the leading edge of the pulse 50 Hz / 1 kHz /, the first key 50 opens and pulses U _d 90 kHz are received at the input of the pulse distributor 51, from the outputs of which they are fed, starting from the first, to the first, clock, bit inputs in parallel 16 registers 56, to the third information inputs of which codes from the ADC 30/33 / are received. For the duration of the frame, block 49 receives 1800 codes. For an hour of shooting, 180,000 blocks of 49 registers of sound codes are filled, Fig.6. The capacity of the drive 31/34 / sound codes is: 1800 _bit × 180,000 = 324 × 10 ⁶ 16-bit codes or 324 × 2 × 10 ⁶ = 648 MB. When playing audio information, the switch 292 in position 1 at 50 Hz of the frequency of stereo pairs or in position 2 at a frequency of 1 kHz. When issuing codes, the key 52 is opened by the signal U _{to the} frequency of stereo pairs and passes pulses U _d to the input of the second pulse distributor 53, from the outputs of which the output signals are sequentially fed to the second inputs of the bits of the registers 56 and 1800 sequential sound codes are transmitted from them to the block 32/35 / . For multiple issuance of codes from blocks 49 registers of sound codes, the output of each bit in the registers 56 (Fig. 7/) is connected to the third input of its bit through a diode, each bit is again filled with a signal. To exclude the mixing of signals to the first inputs of the bits, clock, from the distributor of 55 pulses at the moments of the return of the signals in the third bits receive clock pulses.

The operation of the camcorder.

When shooting video information, switch 29 ₁ is set to position 1 when shooting at a frequency of 50 Hz, to position 2 / Fig. 1/ for high-speed shooting 1 kHz, switch 29 ₂ in position respectively also 1 or 2. Matrices FDI 3 and 8 form analog video signals pixels that are read horizontally from all lines in parallel and go to the outputs. 6000 ADCs simultaneously and in parallel convert video signals into 8-bit codes, which enter 18-23 digital video information storage devices. Sound codes from the ADC 30 and 33 enter the drives 31, 34 sound codes. Codes of video signals and sound are recorded frame-by-frame in drives 42 _1-180000 frame codes and in drives 31, 34 sound codes for an hour or three minutes in high-speed mode. Before viewing, the viewer adjusts the field of view of the glasses 40 on the screens 37, 38 from the viewing point: puts on glasses, moving the right screen 38 in the frame selects the distance between the screens so that each of them enters the field of view of its window. Exact adjustment of the visual fields is performed by turning the windows of the glasses and changing the lengths of their blends. During playback, the switch 29 ₁ is placed in the shooting mode, the switch 29 ₂ is placed in the position corresponding to the same mode. The pulses of the frames are fed to the input of the distributor 28 of the video camera, from the outputs of which they are fed to the third control inputs / Fig. 3/ of the drives 42 frame codes and to the third control inputs of the blocks 49 registers / Fig. 7, 8 / sound codes and sequentially issue codes from them video signals and sound to the inputs of blocks 36, 32, 35. From blocks 36, the pulses of the bits of the codes go to the control inputs of the emitting cells, on the screens 37, 38 during the frame period the right and left frames of the stereo pair are displayed, received by the right and left eyes of the viewer. Video information and sound codes can be played repeatedly with the power turned off in the camcorder, to save the video information and the sound user rewrites them on the appropriate long-term medium. After turning off the power in the camcorder, the drives are de-energized and the information is deleted, the camcorder is ready for new shootings. The camcorder implements a high-speed shooting mode, which can also be viewed at a frame rate of 50 Hz, i.e. 20 times slower, which makes it possible to see the slow development of its fast-moving event / process /, the method of two-screen playback of stereo video information is applied, and glasses of separate fields of view do not require complex technologies for their manufacture.
