Блоки регистров выполнены идентично /фиг.6/, каждый содержит десятиразрядные регистры 49 числом 10⁶ по числу разрешения матрицы и последовательно соединенные ключ 50 и распределитель 51 импульсов с выходами от первого по 10⁶. Информационными входами блока 7 регистров являются первый - десятый входы всех регистров 49, выходами являются поразрядно объединенные первый - десятый выходы всех десятиразрядных регистров 49. Первым управляющим U_от входом является первый управляющий вход ключа 50, подключенный к объединенным выходам диодов Д3 и Д4, вторым управляющим входом 50 МГц /или 1 ГГц/ является сигнальный вход ключа 50, подключенный к объединенным выходам ключей 25, 26 /фиг.1/.

При открытом ключе 50 на вход распределителя 51 импульсов поступают импульсы дискретизации частоты выдачи U_выд1 50 МГц или U_выд2 1 ГГц.

Каждый накопитель 18-23 сосредотачивает за час съемки 18000 периодов кадров. Емкость одного кадра составляет 1000×1000=1 Meгадесятиразрядных кодов. Емкость одного накопителя 18-23 цифровой видеоинформации за час составляет: 1 мегадесятиразрядных кодов ×

=180000 Мегадесятиразрядных кодов за час или 180 Гигадесятиразрядных кодов за час. В накопителях 18, 19, 20 накапливаются коды соответственно цветов В, G, R, в накопителях 21-23 коды цветов соответственно B₂, G₂, R₂.The receivers 3, 11 of the images are identical, each contains a matrix of 1000 _rows × 1000 _samples from elements 10 ⁶ . Each matrix element is represented (Fig. 3/) by a triad of three transducers "radiation brightness - code": the lower left transducer receives red R radiation, the upper transducer receives green Q radiation, the lower right one receives blue B radiation. The transmitters “radiation brightness - code" are identical (Fig. 4/), each contains an opaque case 42 of the corresponding form of insulating material, a color filter 43 of one of the primary colors R, Q, B behind the color filter in is placed in the front / entrance / end of the case an opaque baffle 44 is fixed with a micro lens 45, along the optical axis of which at an angle of 45 ° to it ten ten translucent micromirrors 46 _1-10 are arranged and rigidly fixed by the number of bits in the code. On the side of the housing, to which the translucent micromirrors 46 are rotated, there are ten corresponding photodetectors 47 _1-10 , receiving radiation reflected from the micromirrors and issuing electrical signals to the control inputs U _{from the} keys 48 _1-10 in blocks 4-6 / 12-14 / of the keys . The luminous flux after the color filter 43 enters the micro-lens 45, directing the radiation along the axis to the centers of the translucent micromirrors 46. The principle of conversion "radiation brightness - code" is that each translucent micromirror 46 located in front passes the light stream weakened by two times, which corresponds to the principle of binary code. In translucent micromirrors there are beam splitting coatings that fulfill the ratio of reflected radiation to transmitted as 1: 0.5 [2, p.223]. The technical result of the Converter "radiation brightness - code" is to obtain a code of the input radiation with the speed of light propagation. Binary codes from the converter are represented by a sequence of unit signals in the bits of the code according to the number of micromirrors 46 through which light passed, in the bits through which micromirrors the light did not pass zeros, so in code 0001111111 the radiation passed through translucent micromirrors 46 _1-7 , and through micromirrors 46 _8-10 light did not pass. The high-order bit in the code corresponds to a translucent micromirror 46 ₁₀ , the youngest - a micro-mirror 46 ₁ , the highest-order bit in the code corresponds to a photodetector 47 ₁ , and the youngest - 47 ₁₀ . To obtain clear pulses in code bits with given parameters in amplitude and duration, signals from photodetectors 47 _{1-10 are} replaced by pulses with specified parameters by using keys with the number 10 ⁷ in each key block 4-6 and 12-14, respectively, of the frame resolution and the number of bits in the code issued from the output of the shaper 36 pulses / 1 /. Each transducer "radiation brightness - code" is served by ten keys 48/4 /. The signal from the photodetector 47 opens its key 48, through which, in the open state, a frame frequency pulse with the corresponding amplitude and duration generated by the pulse shaper 36 passes from the signal input. For a frame, one pulse passes through key 48, since all codes go in parallel and synchronously, the frequency is equal to the frame rate from output 4 of the synthesizer 27 frequencies / 1/50 Hz or 1 kHz from output 2. Pulse duration at different frame frequencies there must be one that satisfies both frame rates, for example 50 μs. At the input of the pulse shaper 36, the frame frequency pulses arrive, and the frame frequency pulses with the specified amplitude and duration go from its output. The output of block 36 is connected in parallel to the combined information U _f inputs of blocks 4-6 and 12-14 keys. The frame formats in the receivers 3 and 11 of the image are the same in size, and the sizes of the matrix elements also depend on the size of the frame format. So with a format of 36 × 36 mm and with a resolution of 1000 × 1000 pixels, the dimensions of one element of the matrix / triad of converters / should be 36 × 36 μm /

/ transverse dimensions of the transducer housing should be 18 × 18 microns / 3 /. The manufacture of triads and converters of such sizes is possible with the involvement of appropriate nanotechnology. The location of the triads in the rows of the matrix in figure 5. Codes in parallel form synchronously arrive from the outputs of the keys of blocks 4-6 and 12-14 in blocks of 7-9 registers and in blocks of 15-17 registers. The blocks of the registers are identical (Fig.6/), each contains ten-digit registers 49 with the number 10 ⁶ according to the matrix resolution number and the key 50 and the pulse distributor 51 connected in series with outputs from the first to 10 ⁶ . The information inputs of block 7 of the registers are the first to tenth inputs of all registers 49, the outputs are the bit-wise combined first to tenth outputs of all ten-bit registers 49. The first control U _{from the} input is the first control input of the key 50, connected to the combined outputs of the diodes D3 and D4, the second control the input of 50 MHz / or 1 GHz / is the signal input of the key 50 connected to the combined outputs of the keys 25, 26/1 /. Key 50 opens with a leading edge of the frame rate pulse, and closes with a trailing edge of the pulse. With the key 50 open, pulses from the sampling frequency of the output frequency U _vyd1 50 MHz or U _vyd2 1 GHz are received at the input of the pulse distributor 51. The signals from the outputs of the distributor 51 pulses are signals for issuing codes sequentially from registers 49 _1-10 6/6 / to the corresponding information inputs of the first and sixth drives 18-23 digital video information / 1 /. Each 18-23 drive focuses 18,000 frame periods per hour of shooting. The capacity of one frame is 1000 × 1000 = 1 Mega-ten codes. The capacity of one drive 18-23 digital video information per hour is: 1 megadext-bit codes ×

= 180,000 Mega-ten-digit codes per hour or 180 Gigabyte-bit codes per hour. In drives 18, 19, 20, codes of colors B, G, R are accumulated, respectively, in drives 21-23, color codes of B ₂ , G ₂ , R ₂ , respectively.

The output of the second switch 63 is connected to the input of the second pulse distributor 64, the outputs of which are connected with U _vyd first to 1800 th parallel to the second inputs of the register 67. The bits Trans the first control input U _{from the} third key 65 is connected to the output of the second key 63, and the output of the third key 65 is connected to the input of the pulse distributor 66, the outputs of which are sequentially connected to the first, clock, inputs of the bits of the registers 67 _1-16 . For multiple sound reproduction from blocks of 60 registers, the output of each bit in the registers 67 is connected to return the signal to the third input of its discharge through the diode, each bit is again filled when the signal is issued, and to prevent mixing of signals from the pulse distributor 66 to the first, clock, bit inputs clock pulses arrive at the moments when the signal returns to its discharge. The outputs of 180,000 blocks of 60 registers are bitwise combined and are 1–16 outputs of the drive 31/34 / sound codes / Fig. 10/ and connected to 1-16 information inputs of the driver 32/35 / analog audio signal / Fig. 1/, each driver 32 The 35 analog audio signal includes a series-connected DAC of sound signals, a low-pass filter and a power amplifier connected to the input of the speaker Gr. The left 38 and right screens 39 are identical, each comprising respectively elements of a frame resolution of 10 ^6/1000 × 1000 / pixel. Each matrix element forms a pixel with three radiating cells emitting the primary colors R, Q, B. The general view of the matrix element and its top view inside in Fig. 13 and includes an opaque housing 68 of the corresponding shape, combining the three radiating cells 69, 70, 71. Left the lower emitting cell 69 emits a red R color, the upper 70 emits a green G, the lower right 71 emits a blue color. Each emitting cell contains / Fig. 13, 14 / in the input end of the housing a micro lens 72, which acts as a micro lens, in the output end of the housing there is a color filter 73 of one of the primary colors, between the micro lens 72 and the color filter 73 there is a diaphragm 74 having a cylindrical body 75 with ten corresponding slots according to the number of bits in the code, ten translucent and neutral microfilter filters 76 (Fig. 14, 15) are attached to their own in the slots along the optical axis of the microlens, attached to its own: micropiezoelectric element am 77 _1-10 , the first ends of which with two control inputs are rigidly fixed in the housing of the matrix element, translucent neutral microfilter filters 76 are attached to the second free ends of the micropiezoelectric elements, which, in the absence of control pulses from the blocks of 37 pulse amplifiers (Fig. 2/) completely block the radiation flux from microlenses 72. Cells work identically. The principle of their operation is that each translucent neutral microfilter in front of them passes a light stream weakened by half into the microfilter next to it, which corresponds to the principle of a binary code. The radiation from the sources of irradiation / backlight / superbright white LEDs is directed along the axis of the microlens 72 through the semitransparent neutral micro-filters 76 to the color filter 73, which gives the output radiation a corresponding color. The inputs of the micropiezoelectric elements are the control inputs of the matrix element and are connected to the corresponding outputs of the pulse amplifiers in blocks 37 _{1-6 /} Fig.2/. In the absence of control pulses / signals of code units / micropiezoelectric elements 77 (Fig. 14) are in an unstressed state, and all translucent microfilter filters 76 are located along the axis of the microlens 72, the radiation flux is blocked. With the arrival of control signals at the inputs of micropieoelectric elements 77, their free ends are bent and translucent microfilter 76 is removed from the radiation stream for a frame period of 40 ms / 1 ms /. The microfilter removed from the radiation flux corresponds to a unit in the code bit, and the microfilter removed from the flux of radiation corresponds to zero in the code digits / Fig. 15/. With the code 0001111111, the microfilters 76 _1-7 are removed from the stream, the microfilters 76 _{8-10 are} not removed from the stream. Upon receipt of the code from one unit 1111111111, all translucent microfilter filters 76 _1-10 are removed from the stream, and maximum radiation is emitted from the cell. Micro-piezoelectric elements are used tubular piezoelectric elements that work on bending, strong and reliable during prolonged operation [3, p.27]. Emitting cells are made as miniature as possible with transverse dimensions up to 1 × 1 mm. Radiation from three cells produces a color tone and pixel brightness. The microline 72 is irradiated with superbright white LEDs located in the corresponding quantity and in the corresponding order inside the screen body on its back side.

The sequence is performed by pulses from the outputs of the distributor 59 pulses, the input of which receives the pulses of the frequency of the stereo pairs. With the arrival of the leading edge of the pulse 50 Hz / 1 kHz /, the key 61 is opened (Fig. 11) and 90 kHz pulses are supplied to the input of the pulse distributor 62, from the outputs of which they are fed to the first inputs of the bits in parallel to sixteen registers 67, to the third information inputs of the bits of the registers 67 codes with ADC 30/33 / come. For the duration of the frame in block 60 receives 1800 codes of sound. During the hour of shooting, 180,000 blocks of 60 registers of sound codes are filled. The capacity of the drive 31/34 / s sound codes is: 1800 _bit × 180,000 = 324 × 10 ₆ 16-bit codes, or 628 MB. To play the sound, switch 29 ₂ in position 1 at 50 Hz or in position 2 at a frequency of 1 kHz shooting.

With the arrival of the leading edge of the second pulse of the frame, codes from registers 49 _1-10 6 of blocks 7-9 and 15-17 are sequentially issued with a sampling frequency of 50 MHz or 1 GHz to drives 18-23 of digital video information, and the registers in blocks 7-9 and 15 -17 are instantly filled with codes of the second frame. Sound codes from the ADC 30, 33 enter the drives 31, 34 sound codes. Before viewing the video information, the viewer adjusts the field of view of the glasses 41 from the viewing location. During playback, switch 29 ₁ is placed in the shooting mode, switch 29 ₂ is placed in the shooting mode position. The frame pulses are fed to the input of the camcorder's 28 pulse distributor, from the outputs of which they are fed to the third control inputs (Fig. 7/) of drives 53 frame codes and to the third control inputs of the sound code drives (Fig. 10/) and issue video and sound codes, respectively, in blocks 37 _1-6 and to blocks 32, 35.

Video information and sound codes can be played repeatedly if the power in the camcorder is not turned off. To save video information and sound, the user rewrites them on a long-term carrier. After turning off the power in the camcorder, the drives are de-energized and the information is erased.
