The line 2 shaper clocks the reading of information from the memory cells of the main memory unit 1 and the output of the information from the generator 3 output.

The first counter of 7 points is disconnected from the counter of 6 lines by the presence of a setup input on which it is possible to set an arbitrary initial state at its output, and the input gating the entry of information on the installation input, as well as the absence of an input from it. produces a primary line scan. The sum of the counting input of the counter 1 1 receives pulses of the image sampling rate horizontally. Typically, this frequency is equal to the maximum, what else can a video amplifier TV receiver miss. For example, for standard TV receivers used as indicators, this frequency is 10 MHz.

During the DGS interval, the control input 20 of the device (at the same time 15 frequencies each. The counter of the computer control bus is outputted and a pulse is sent to the input of counter 7, allowing for this time the entry of information on the setup input) to the output of counter 7 is set to the initial state, which is equal to the value of what time it is set at its second entrance. The setup code of the initial state of the counter 11 is outputted at the input 18 (data darkness from the computer). GIS, get to the second input element

c (vertical straight lines, for example, turn into broken lines).

In order to increase the accuracy of reproduction of the image when it is tilted by arbitrary angles in the horizontal line, it is necessary to shift the horizontal scanning samples to distances smaller than the interval between two adjacent horizontal scanning samples.

The summing input of the clock counter 9 is supplied to the frequency from the output of the generator 8, the value of which is significantly greater than the value of the horizontal scanning frequency, which is formed after dividing the frequency of the generator 8 by the counter 9, the clock is no different from

counter 7, only the lower clock bits of the computer data are connected to the installation input of the first counter of the 9 clock frequency, and the high bits of the 20 uiHHbi computer data are connected to the setup input of the first counter 7. With a monotonous change during each subsequent SGS of the setup code at the output of the EVM data bus, the image will tilt at any angles to the X axis, depending on Hjara

OR 13, sets register 14 to a single monotonic change in setpoint, since there is no state. Register 14, horizontally connected image shift now

with the control input of the switch 15,

the switch causes the connection of the output of the counter 7 to the input of the former 2 line scan. If a constant code is sent to the installation input of counter 7 on input 18 (data bus EV) during the OGS interval (a pulse of recording resolution of this code is simultaneously issued to the strobing input), then a statistical display will appear on the TV indicator screen image 30

may be less than the minimum line spacing of the image on the TV screen. The boundary line of the tilted image remains straight. (In all - K (JM case at a sufficiently high generator generation frequency 8 its kinks remain imperceptible to human vision). At arbitrary changes in the settings made during SGI, the image can be curved according to this law.

horizontal speed The speed of movement and changes in the configuration will depend on the size of the radio set of the image depends on the rate of change of the settings.

of this code, if this setup code changes, for example, monotonously, with a period that is larger than the period of the OIG, and measured by the same algorithm as the 9-clock counter and the 7-point counter, its function will start during KGI, 40 negate, respectively, the 10-hour counters, then the image on the TV screen will move and 1 1 points, horizontally in the direction, depending on whether the TV image is growing or diminishing. send the switch 15 to the driver 2 input WAITS of counters 7 and 11 that have different and varying setpoints alternately (while one of the point counters is connected to the driver 2, the setpoint can be changed at another point counter), on the TV indicator screen 50 various dynamic changes (see fig. 2). The NOT element 12 eliminates the possibility of entering the setpoint in the 9-clock counters and 7 points, if the setpoint is entered in the 10-clock and 11 points counters; and vice versa, if the setpoint is entered to 9 counters of a clock frequency of 7 points, then if there is a setting at the inputs of the input of the last level meters} I, the difference of the setup code.

If, for definiteness, the value of the installation code is monotonously changed by one unit with each successive SGI, the image on the TV screen will tilt 45 ° with respect to the X axis in the direction depending on whether the binary value of the installation code increases or decreases.

The accuracy of the reproducible image on the screen of a television indicator is determined by the size of the frequency grid of horizontal scanning samples, the minimum discretion of which is always limited by the bandwidth of the video amplifiers of TV indicators. Therefore, the image when tilted at arbitrary angles to the horizontal axis (except for the angle of 45 °) significantly distorts

5 frequencies. Counter

c (vertical straight lines, for example, turn into broken lines).

In order to increase the accuracy of reproduction of the image when it is tilted by arbitrary angles in the horizontal line, it is necessary to shift the horizontal scanning samples to distances smaller than the interval between two adjacent horizontal scanning samples.

The summing input of the clock counter 9 is supplied to the frequency from the output of the generator 8, the value of which is significantly greater than the value of the horizontal scanning frequency, which is formed after dividing the frequency of the generator 8 by the counter 9, the clock is no different from

counter 7, only the lower clock bits of the computer data are connected to the installation input of the first counter of the 9 clock frequency, and the upper bits 0 uiHHbi of the computer data are connected to the setup input of the first counter 7. With a monotonous change during each subsequent SGS of the setup code at the output of the EVM data bus, the image will tilt at any angles to the X axis, depending on Hjara

monotonous change of the setting, since the image shift horizontally is now

may be less than the minimum line spacing of the image on the TV screen. The boundary line of the tilted image remains straight. (In all - K (JM case at a sufficiently high generator generation frequency 8 its kinks remain imperceptible to human vision). At arbitrary changes in the settings made during SGI, the image can be curved according to this law.

According to the same algorithm as the 9-clock counter and the 7-point counter, 0 clocks and 1 1-dots, respectively, function, respectively

If during each scan line of the television image, when switching to switch 15, the INPUTS of the counters 7 and 11 alternately connect to the INPUTS of the counters 7 and 11 that have different and differently variable settings (while one of the counters of the points in the former 2 is connected the setpoint can be changed); on the TV screen, the image will make a variety of dynamic changes (see Fig. 2). The NOT element 12 eliminates the possibility of entering the setpoint in the 9-clock counters and 7 points, if the setpoint is entered in the 10-clock and 11 points counters; and vice versa, if the setpoint is entered to the counters of 9 clock frequency of 7 points, then if there is a input at the inputs of the input of the setpoint of the last level meters} 1Я, times5

the decision maker setting,) 1a the corresponding inputs of the 10 clock frequency counters and 11 points will be the level that fixes the setting.

Switchboard 15 is controlled by the input to which the output of register 14 is connected, node. the night of its input to the output of the element L lii To the beginning of each possible move the bars are sent to the frontier unit, and 1i; (11 to the second input of the element OR 13 lieiHCTj) 4 connects to the input formira-1e; 1 2 line sweep B1, 14 () d of the counter 7.

The switch 15 operates as follows.

When a unit arises at the input of an element of the IL 21 at the output of its “O, setting the n outputs of the 2I-IL elements of the grun 22 to logical” 1, thereby allowing the passage of the code installed on the nerve inputs of the elements. Copies of 2 I-IE groups 23 out of n elements 2I-NR., on the inputs of elements 2 I-НN, ground 24 of n e. items 2 I-NR.

And vice versa, when a local "O at the input of the element HE 21 at the outputs of elements 2 AND-NOT of group 24 is detected, the state of the BTCjpbix of the inputs of the elements 2 and N-НР of group 22 should be indicated.

The invention allows an org to be able to simultaneously locate in the field of the screen several horizontally any fragment of images in the form of codes recorded in the memory of the regeneration of a television frame and which in the normal reading mode would be displayed on the screen only once. Moreover, each individual image can be divided along the A axis to the required number of sockets and each of them or all together can be tilted with curvature of them forming or without curvature, and also shifted to an arbitrary distance from the vertical edge of the screen of the television indicator. All program modes are computer controlled.
