Abstract

The invention relates to television. The purpose of the invention is to increase the information content of the video signal by introducing the signal of isophoto serial numbers. The device contains a clip 1 of the input video signal, a comparators block 2, a selector 3 horizontal sync pulses, a delay block 4, a shaper 5 write pulses, character generator 6, a selector 7 of the first pulse of a pulse sequence, a switch 8 with an output terminal 10 and a converter 9 duration - the number of pulses. The device generates a video signal containing a horizontal sync pulse, a code signal of sequence number first in the direction of the line formed isophotes and multi-colored isophotes lines with a constant offset providing a gray background on the photographic carrier. Since the color of the isophotes is determined by the direction of intersection of the reference levels, the magnitudes of the signals of the formation of all subsequent isophotes in the row can be determined from the magnitude of the signal for forming the first isophote. 3 il.

The invention relates to television, namely, devices for processing video signals of an image and then displaying it on a recording medium (e.g., photographic).

The purpose of the invention is to increase the informativity of a video signal by introducing a signal of isophot serial numbers.

FIG. 1 shows a structural, electrical circuit of the proposed device; in fig. 2 - timing diagrams for the operation of the device; FIG. 3 shows an example of a blank recording medium with an image.

The device contains a clip 1 of the input video signal, a block of 2 comparators, a selector 3 horizontal sync pulses, a block 4 delays, a driver 20 5 write pulses, a character generator 6, a selector 7 of the first pulse of a pulse sequence, a switch 8, a converter 9 duration - the number of pulses and the output terminal 10 of the switch .

Form 11 of the recording medium contains a field of 12 dp of displaying line pulses, a field of 13 dp of displaying the serial numbers of isophotes, and a field of 14 dp of displaying an image.

The device works as follows.

negative impulses and converts into a form suitable for registration on a photographic medium. The output pulses of the imaging unit 5 also arrive at the selector 7 of the first pulse of the pulse train, which outputs to its output during the presence of the resolving potential from the output of the delay unit 4, the first generated pulse of the intersection of the reference level from the outputs of the comparator block 2 in the information part of the data line (Fig. 2 ). Using this pulse, the state of the generator 6 records the state of the outputs of the block 2 of the comparators, i.e. the number of the isophotes first formed on this line is determined. This code is stored in the character generator 6 and with the help of a control signal from the output of block 4 of delays (Fig. 2b) and pulses from the output of converter 9, the duration - the number of pulses through the second information input of switch 8 is output to the output terminal 10 of the device (fig. 2 d) at the beginning of the next line, after which the isophote number code of the described line for the next line is determined and stored by the character generator 6.

Thus, the device generates a video signal containing a snoot-input video signal (Fig. 2a) for 35 Q sync pulse, the signal of the code pore clamp 1 comes to the comparators unit 2 and the selector 3 horizontal sync pulses, which, after the termination of the horizontal synchronizing signal, gives a short pulse to the unit 440

The first one in the direction of the line formed isophotes and the multi-colored isophots lines with a constant offset, providing a gray background on the photographic carrier. Therefore, the carrier blank 11, when displaying the generated video signal, contains a field of 12 line pulses, a field 13 of the sequence number of the first generated telemetry information (Fig. 26) j isophotes in a row, and a field 14 of the informant and inverted signal in the rest of the image in the form of time difference for registration information part of the line. Unit 2 contains a set of parallel-running comparators, the reference levels of which are executed correspond to the isophote formation scale. Output parallel pulse sequences of block 2, the polarity of which is determined by the direction of intersection of the reference levels,

colored isophotes. Since the color of the isophotes is determined by the direction of intersection of the reference levels, it is not difficult to determine the formation values of all subsequent isophotes in the row of the first isophore forming value.
