The image registration cycle on the target medium occurs as follows. The control flare control device input receives a pulse. The trigger is set to the zero state of the counter 8 and 10 and rewired by the synchronizer 6 to the recording mode. The first counter performs the counting clock frequency pulses on the FK module N. The number of fields in the image decomposition (for example, Mp 2) The output pulses with a frequency F-K / Nn arrive at the counting R-AP of the second counter 10 and the second control input of the synchronizer P. The second counter 10 performs the counting of the KK / N frequency pulses. modulo ni. equal to the number of display elements in the image line on the trap line, and generates a code for the column number of the record Generator 11 in each horizontal scanning period generates a sequence of clock pulses at the output whose number is equal to Nr elements from the reflection in the image line. the first element, the display in the image line, np - I, decide that the chopper 13 is set to the nil ° hp state of the lowercase clock pulses and performs a count of clock pulses ovRu “doirokro” Code of the number of a clockwise imp-gP; n i i ode counter TZ comes to the input of the comparator 14. The second input of the comparator 14 receives the parallel code of the column number of the record from the output of the counter 10. When the exit codes are equal

the comparator 14 appears pulse, which is fed to the driver 1b write pulses. From the first output of the writing pulse imager 15, a pulse of duration ti T / C / NM (where Tc is the horizontal scanning period) is fed to the control input of sample and storage unit 1b, which memorizes the instantaneous values of the information signals of the primary colors inputted 17 devices. From the output of block 16, the sample and storage of a sample of signals are fed to the information input 2 of the recording units. From the second output of the imaging pulse generator 15, a pulse delayed relative to the beginning of the pulse of the first output at the time of switching of the sampling and storage unit 16 is fed to the second control input of the recording unit. Thus, during T "on

5, the information input 2 of the registration unit 1 receives samples of the signals of the main colors of the display elements corresponding to the vertical column of the image having the number coinciding with

0 by the frame number at the output of the counter 10. The period of the following signal samples is equal to the horizontal scanning period. In an odd field, odd fields are formed; in an even field, even elements of a vertical column are formed. For

5 progressive image recordings should be installed. The synchronizer 6 generates control signals for the step drive of the photosensitive carrier 23. Start of carrier movement

0 corresponds to the Start signal input to the device 7. The carrier is stopped by the output pulse of the counter 10 after the last column of the image has been recorded. Signal from the output of the first

5 of the counter 8, arriving at the second input of the synchronizer serves to synchronize the stepper drive 24. Moving the end carrier to the step occurs after recording all the elements of the vertical column

0 from odd and even image fields. In block 1, the registration of a sample of signals of primary colors via information input 2 enters the switch 20 (for example, three-channel), controlled via

5, the second signal input 5 from the second output of the driver 15 pulses. The outputs of the switch 20 are connected to a modulator 19 (for example, a three-channel). Scanner 22 is synchronized by frame sync pulses arriving through

the third control input 4 and sweeps the rays in a direction perpendicular to the direction of movement of the target carrier. Thus, the scanner performs a frame scan with a period T, and the carrier drive performs a line scan with a period between the steps of moving Tk iNn. The scanner 22 can be performed, for example, in the form of an optical-mechanical deflector.

A device for recording information allows to obtain halftone color hard copies from the screens of televisions, television displays and video monitors. The recording time of a color image frame with a resolution of 512x512 elements with two fields of interlaced resolution is about 20 seconds.

A device for recording information allows recording full-color half-ton television images, i.e. any plot information, which significantly expands the field of application of the device.

A device for recording information can be widely used in information telepizionnyh systems, systems for reproducing and recording information from video disks, in electronic photography, in systems of medical diagnostics, in home appliances for recording television images.
