The drawing shows a structural electrical circuit of the proposed device.

A device for forming a color-music image signal contains a series-connected sound reproducing device 1 and a compressor 2, the output of which is connected to the input of the electrical sound analysis unit 3 and to the input of the analyzer 4 pauses, a program switch 5, n inputs of which

A feature of the unit 3 for analyzing the parameters of an electrical sound signal is that this block contains analyzers of electrical sound signal parameters combined on inputs. The total number of analyzers is equal to the number of analyzed parameters. Parameters analyzers are digital measuring instruments, the outputs of which are the outputs of the electric sound signal parameters analysis unit 3.

The device for forming the color-image music signal of the image operates as follows.

An electrical sound signal from the output of the audio reproducing device 1, which can be used as a tape recorder, player, low-frequency path of a radio receiver or a TV, etc., is fed to the input of compressor 2, which has a logarithmic characteristic and serves to compress the dynamic range of the original sound waves with the aim simulation of the law of Weber-Fechner. From the output of compressor 2, an electrical sound signal compressed over the dynamic range is fed to the input of the electric sound parameters analysis unit 3 and the 4 pause analyzer input; the latter records the appearance of pauses in the electrical sound signal and if there is a pause for a certain length; It generates the control signal in analog form, which is fed to the (n-fl) -ft input of the program switch 5 and to (w-1-1) -th input of the control block b. The block-3 analysis of the parameters of the electrical sound signal analyzes the electrical sound signal input to the input according to n parameters (as analyzed

parameters of the sound signal can be selected loud dynamics, tempo of music, rhythm, timbre development of sound, tonal development, movement on registers

etc.) and generates, in accordance with their size, n signals in digital form, which are supplied to n switched inputs of the program switch 5, which, in accordance with the current program, switches

 w of p (type) inputs with m outputs. The total number of programs N can be determined by the formula. A program change occurs at the moments of the presence of pauses of a certain size according to the signal of the analyzer 4 pauses, which is fed to the (n + 1) -th input of the switch of 5 programs.

Switch 5 of the programs can be executed according to a two-step scheme, in which first the "number of the signal arriving at the (n-f 1) -th i.khod, and

0 then the appropriate connections are made on the basis of the algorithm laid down in the design.

From the outputs of the switch of the 5 programs, the signal is digitally fed to the corresponding inputs of the control unit 6, to the input of which a signal is given about the presence of a pause from the output of the analyzer 4 pauses.

Sync generator 7 generates linear spacing increasing bit functions of horizontal and vertical sampling -

0 digital sweep functions (CRF), which are used in the sync generator circuit to generate synchronization and blanking signals and simultaneously in the shaper 8 static signals, the shaper of dynamic images and the shaper of 13 figures displacements of the frame as the primary (reference) signals for the formation of .

The generator of the 8 signal of statistical images using digital synchronizing functions of the synchro-generator generates a nomenclature of still images. Such signals may be point or multi-point fields, color bars, color mosaics, circles, circles, and complex images.

The images synthesized by the imaging unit 8 are constructed from a set of simpler images, which are vertical and horizontal lines of various widths, as well as rectangles and

0 squares formed by the intersection of these lines, including elements of a point field and rectangular areas. The width of the lines and the sizes of the rectangles are determined by the periodicity of the low-order discretization functions that form them, and the number

them on the raster are the periodicity of the high-order discretization function. This allows using the control unit 6, which generates control signals proportional to the change in the analyzed parameters of the audio signal, to change not only the structure of still images, but also the dimension of the components (elements).

The shaper 8 of the signal of static images is expediently performed according to a two-step scheme in which the main images are first formed, and then the synthesis of the combined images is performed on their basis.

To obtain at the same time a simple and easily controlled circuit structure of the driver 8, the most expedient base for the execution of the first steps of this block are permanent storage devices (ROM) in the form of large integrated circuits. The second stage of the formoron; 1th, 1-8 it is advisable to perform with the use of; iiii; iiincM of the digital signal switches II cmM of logical addition.

: P () The impeller 12 of the dynamic Kiix image generates images that can move on the raster in directions and at speeds depending on the analyzed parameters of the audio signal. These images may, depending on the current program, have a special shape or repeat images of the imaging unit 8.

Dynamic image generator 12 is also designed as generator 8, but unlike the latter, the digital sweep functions of its own frequency divider are used as primary signals in the formation circuits, the construction of which, the number of bits and the clock frequency at the input are similar to the clock frequency divider. The binary bits of the controlled splitter 11, the frequencies that form the digital bit functions of the horizontal and vertical sampling, are set to a certain initial position, respectively, in the inverse and horizontal intervals and the vertical scanning intervals. At the same time, digital spreading functions and the signals forming on their basis are rigidly connected in phase with the synchronization signals. To move the image on the raster, it is necessary to change the setting code of the bits of the controlled frequency divider 11 with a certain clock frequency. Changing with the help of control signals of the control unit 6, proportional to the change of the sound signal parameters selected by switch 5, the setup codes and clock frequencies can be obtained by shifting the image in the directions and speeds that are determined by the change of the selected sound signal parameters. Controlled reversible counters MAY be used to change the setup codes, and controlled frequency distribution 11 frequencies to change the clock frequency and, accordingly, the speed of movement of images.

So the shaper. The 12 dynamic image signals are performed according to a three-stage scheme in which digital bit functions of horizontal and vertical sampling are first formed, moving relative to the synchronization signals, then test images are formed based on them, and finally, the combined images are synthesized and the image is selected.

The most appropriate elemental base for constructing a controlled frequency divider 11, as well as reversible counters included in the driver circuit 12, are recalculated schemes of medium and large degree of integration. The remaining blocks of the dynamic image signal generator 12 are executed similarly to the block of the signal generator 8 of the static image signal.

The shaper of the 13 frame displacement figures in the pause of the audio signal forms resizable geometric shapes on the raster. In addition, it forms separate moving lines separating the raster - straight lines, parabolas, sinusoids, etc. These figures are used in gap illumination for mixing images by slowly displacing one image by another under the action of control signals generated by control block b. In principle, all figures can be generated by digital methods. In this case, the imaging unit 13 is constructed similarly to the imaging unit 12. However, some figures, for the synthesis of which by digital methods, need ultrahigh-speed ROMs and a greater degree of integration that have not yet been mastered by industry, it is advisable to form analog and digital-analog methods.

The logic unit 9, depending on the current program, generated by the program switch 5, in accordance with the commands from the control unit 6, using as the primary signals of the formers 8,12 and 13, synthesizes signals based on them that represent a variety of logical expressions - simple and complex. It can separately pass one or another signal (for example, in the pause of the audio signal, logic block 9 only passes signals generated by the shaper 13 of the frame displacement figures), as well as synthesize disjunctive and conjunctive logical expressions or their combinations.

The combinations of formers 8 and 12, which change in accordance with the change of the analyzed parameters, the sound signal, create colorful, color organ compositions. The operation of this device is controlled by the control unit 6, which can operate both in stand-alone " manual mode and " in automatic color organ mode. In the "manual mode", the control unit 6 generates the control signals depending on the work program defined by the respective switchings of the external control knobs. In this mode, the proposed device, like the prototype, can be used to generate static and dynamic test images. In the automatic color and music accompaniment mode, the control unit 6, depending on the current program selected by the program switch 5, generates control signals that change in accordance with the change of the selected sound signal parameters, and in the absence of a sound signal, at the command of the 4 pause analyzer generates control signals on the control inputs of the imager, 13 displacement figures of the frame and the logic block, providing the moment of creativity imitation and in the light of the pauses. In the absence of the output of the control unit 6, the control signals, changing in accordance with the law of change of the analyzed parameters of the audio signal, are supplied to the corresponding control inputs of the imagers 8 and 12 of the image signals, the controlled frequency divider 11 and the logic block 9. The control signals, in accordance with the change of the analyzed parameters of the audio signal, determine the choice of images formed by the static images generator, as well as their number, scale, color and color saturation The control signals to the control inputs of the dynamic image generator 12 and the controlled frequency divider 11 determine the choice of images, their color gamut and color saturation, as well as the speed and direction of motion of the synthesized images in accordance with changes in the analyzed parameters of the audio signal. The control signals of block 6, arriving at the control input of logic block 9, determine the choice of the type of combinational logic functions formed by the driver 12, i.e., ultimately. these signals determine the type of image generated by the device. Shaper 8,12 and 13 synthesize the signals of the primary colors (R, G, B) in the form of multi-digit code combinations. The conversion of these combinations into an analog signal of a calibrated level is performed by a digital-to-analog converter 10, which, in order to avoid overloading the elements of the transmission path, performs level-coding of the signals depending on their chromaticity. The digital converter can be made in the form of ROM. The proposed device, in contrast to the known one, allows one to obtain a color-music effect and, in comparison with known color-music devices, has the largest number of analyzed sound signal parameters. The use of digital methods of analyzing musical influence parameters and synthesizing a color organ image on this basis in a device allows achieving a high artistic result. In this case, it is possible to achieve the most complete correspondence between the control unit and the output optical device, since according to the well-known formula I ,,,. where the hi-monotonous function, which changes with according to the creative plan, it is possible to carry out the most preferable conjugation of the parameters of the acoustic Φ j (t) and visual - FJ (t) effects. The use of a color television receiver as an output optical device allows, firstly, using the most preferable loudness range (40 - 70 cd / m) and, secondly, receiving colorful color organ compositions of almost any complexity both in image structure and by the nature of the movement, which can not provide any other automatic light organ devices. Direct accompaniment. The proposed device can be used both as color organes for widespread consumption (accessories for color television receivers), and for creating color organes that can be used in television broadcasting to create color organ screensavers and color organ background images.
