The input of the block 5 prohibition elements is associated with the output of the block 6 of the overlapping of geometric elements

image, one of the inputs of which is connected to the information input 4 of the device, and the others to the first outputs of the formers 7-10 geometric elements of the image, the first inputs of which are connected to the information input 4 of the device, and the second inputs to the second output of the synchronizer 1. The second the outputs of the formers 7-10 of geometric elements of the image, the number of which can be arbitrary and determined by the required performance of the device, are connected to the corresponding third groups of inputs of the same formers 7-10.

5Each of the latter (Fig. 2) contains

The first and second blocks AND and 12 coordinate transformations, the outputs of which are connected respectively to one of the inputs of the first 13 ,; second 14, third 15 and four,. This 16 comparison circuits and to the address inputs of the fixed memory blocks 17, the sampling and reading resolution inputs of which are connected respectively to the forward and inverse outputs of the NAND element 18. Other inputs of the coordinate conversion circuits 11 and 12 are the first input of the imaging unit 7 ( 8-10), while others are its second input, the outputs of comparison circuits 13-16 are connected to the inputs of the NAND element 18. The inputs of the second multiplexer 19 are connected to the corresponding outputs of the fixed memory unit 20, and its other outputs to the first input shaper 7 (8-10) which is and The information input 4 of the device, the first and second outputs of the second multiplexer 19 are the corresponding outputs of the former 7 (8-10), the third group of inputs of which are the inputs of the first multiplexer 21, the output of which is connected to the inputs of the inverter 22 and element 23, the second whose input and one of the inputs of the first multiplexer 21 are connected to the first input of the imaging unit 7 (8-10).

The device works as follows.

The geometrical elements formed by the individual shaper can independently move and rotate on the television raster, fully or partially combine with each other and change their shape. Moreover, the shape change occurs in the process of mutual work of the formers 7-10 of geometric elements of the image, and so on, which are controlled by the signals on the information input 4 of the device from the digital computer.

When combining individual geometric elements of the image, it is necessary to eliminate their invisible parts on the screen of the television indicator. This operation is carried out using the block 6 overlaying geometric elements of the image. Regardless of the order in which the signals of the geometric elements of the image arrive at its outputs, they are positioned so that the signal of the image element lying higher than the others (closer to the observer along the line of sight) appears on its first output, the next one on the second and so on The etr is carried out as follows. All signals of the geometric elements of the image are fed to the information inputs of the descramblers included in block 6 of the overlay of the geometric elements of the image. The number of E. de-digifiers corresponds to the number of formers 7-IO of the geometric elements of the invention. The codes of the position numbers of the image elements are supplied to their address inputs. The outputs of the descramblers are connected to the group of elements I. Thanks to such a device, it is possible to arrange the input signals of the block 6 overlaying geometric elements of the image on its outputs in the order of visibility

 on the screen. Signals of geometric elements of the image, redistributed in this way, are fed to the inputs of block 5 of the prohibition elements, designed so that the signal coming to any input prevents the passage of signals coming to the inputs whose numbers are larger than its number and does not affect the passage of signals from entrance with smaller numbers. This eliminates the possibility of the simultaneous appearance of several signals at its output and,

0 therefore, the apparent position of several geometric elements of the image. The signals are then fed to the input of the color-coding block 3, which contains a converter of the position code to a binary code, a block of color memory and digital-to-analog converters.

The converter of the positional code into the binary code assigns to the output number of the block 5 prohibition elements its binary description, which is the address

0 of the color memory block and selects the cell of the memory block into which the luminance codes of the color components of the corresponding geometric element of the image are stored before the device is prepared for operation. These codes are from the output of the block.

5 memories are fed to the inputs of three digital-to-analog converters, where they are converted into analog signals controlling the color of a portion of the screen of a color television indicator corresponding to a geometric image element located at this location.

Thus, in a general view, dynamic, color, half-tone images are formed on the screen of a color television indicator using the proposed device.
