Abstract

PURPOSE:To surely print out a hoped frame by writing the frame of a designated address into a memory when a detected address and the designated address coincide in a magnetic tape reproduction. CONSTITUTION:A video signal reproduced by a video head 1 is supplied through a preamplifier 2, a video signal processing circuit 3 and a switch S1 to a monitor receiver 4 and monitor-displayed. Here, by seeing the monitor display with a frame feed, etc., the address of the hoped frame is confirmed and inputted to an address input circuit 5. When the address detected from the video signal reproduced in a reproducing mode and the designated address coincide, the reproduced video signal of the designated frame is written to a memory 12, and it is read and printed out. Thus, the hoped frame can be surely printed out.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a video No. 111 processing device, and particularly to a V-T-111 processing device.
A system that combines R and a video printer (・, VT

The present invention relates to a device for performing operations.

Problems to be Solved by the Invention Since the above-mentioned conventional method is configured in such a way that when the desired location from pudding 1 is displayed on the monitor, press the Meri switch -=rt:+ノ, especially when playing a video. When going to Zorin 1 and Out 4, generally by the time you press the memory switch, the desired location is often already past, and it is difficult to reliably fill in the desired location in the memory, so if you try to achieve this, Then, there was a problem that took up a lot of time.

In addition, conventional devices that do not have the frame (field) memory mentioned above are configured to perform still playback and output the reproduced video signal to the printer, so generally still playback is performed within 1 to 10 seconds during recording. Repeat the same track 9-
Because the engine is not running (vA qi) - v running has stopped), the S/N ratio deteriorates and high quality pudding 1 - ara 1 ~
There is a problem that I cannot do it.

The present invention enables a desired frame (field) from a V-1-R playback video to be reliably made into a print finish 1, and in addition, a reproduced image with a good S/N ratio can be obtained and a high quality pudding finish 1~ can be produced. The purpose is to provide a signal processing device.

Means for Solving the Problems In FIG. 1, the memory write timing generation circuit 7 compares the address detected from the reproduced video signal with the address of the designated frame (field) from the address input circuit 5, and determines the detected address. Depending on the difference ffi from the specified address, the magnetic tape is rewound or fast-forwarded to the position where the frame (field) of the specified address is played back and the magnetic tape is 717lI-, and both addresses match when playing the magnetic tape. frame (field) at specified address
This is an example of a means for writing into memory.

Check the address of the desired frame by looking at the monitor display by moving two frames, etc., and input it to the address input circuit. When the address detected from the video signal played in the playback mode matches the specified address, the playback video signal of the specified frame is written in a sequential manner, and this is read out and sent to printers 1 to 1.
Au 1~. Therefore, you can print the desired frame without fail.
~au] - is possible, and since what is written in the playback mode is read out and print 1~out 1~ is performed, the SN ratio is high and high quality pudding 1~ can be produced.

FIG. 2 shows the operation timing fi--1 of the present invention.

15 in Fig. 1, when displaying on a monitor, switch S1 is connected to *'A'r Fl, and frame-by-frame forwarding is used for still images; 2. Video I J1 processing circuit 3. The video signal recorded on the magnetic disk is supplied to the receiver 4 via the camera and displayed on the monitor, as shown in Fig. 2 (△). , the frame (field) is located in a part of the vertical blank period (m; -1 from the beginning of the vertical blank period).
The address signal is recorded, and the receiver @ machine 4
The address display section 4a displays the address number of each room (field) in 1. Check the address number on the display section 4a of the member whose desired frame is displayed, and enter this address Y-P into the address input circuit 5. The video signal processing circuit 3 outputs the C address (ii) from the video signal processing circuit 3 to the address detector 6, and the address input circuit 5 outputs 1,
This)7 address signal detection is compared with the address number of the desired room that is set in 9, and is sent to Callan 1 based on the beginning timing of Ii''+7 Meishin-yumi separated by synchronous separation circuit 8. When permission is granted (21st shrine (B)), the built-in counter starts from 1 (Figure 2 (C)), mH
1, the address signal (Fig. 2 (r')) is detected by the address capture signal (Fig. 2 (D)). Also, the address number comparison is detected by the synchronization separation circuit 8. The addresses of the C frame are compared based on the odd field/even field discrimination signal, and the addresses of the field are compared based on the vertical synchronizing signal (line 41).

Here, in the case of (designated address) < (detected address), convert the magnitude of the deviation into time and 1. 1: Data and a rewind command are supplied to the 1-total control circuit 9, and the 10-dob stun motor 10 is driven to rewind the designated 7-dress to the output device.

Conversely, in the case of (specified address) 10 is driven and the specified address is C.
A 6-magnitude fast-forward is performed. When such predetermined rewinding or fast forwarding is performed, the magnetic j-b(, 1 peak state) is performed, and the memory write timing generation/1 circuit 7 compares the specified address and the detected address. Note that in the case of (designated address)>(detected address), the 11th state is held again.

When both addresses match (actually, the detection address number b'N specified address number"; the one that is n before i (n + 1)), the address [) is From the vertical synchronization signal, for example, the input command signal (Fig. 2 (G)) is received from 4H [81] and is delayed by the delay circuit 11 to be output to the printer side. 3. This H extension circuit 11 is provided to match the timing at which data arrives at the printer's printer 12 and the timing at which the data arrives at the printer's printer 12. .In response to the write command to this message 12, the video signal of the specified frame taken out from the video signal processing circuit 3 of
AD converter 14 via interface 13 of J printer
It is converted to 〇 and written into the memory 12.

When reading is completed in step 12, the mode is set to readout, and the image of the desired room read out (IX y, 41j,
[) After being subjected to D△ conversion by the △ converter 15, it is converted into a signal necessary for the printer 1-ara 1- by the printer processing circuit 16,
The pudding 1-ara I~ is carried out in the pudding 1~head 17.

If you want to monitor the output images from Print 1 to No. 6, connect switch S1 to the terminal.

As described above, according to the present invention, it is possible to reliably print out the desired rule, but there is no need to print out the sprue iN+cow picture from print 1 to print out, and write it again with Vt-. Since the contents are read out and output from pudding 1 to au 1, it is possible to produce pudding 1 with a high signal-to-noise ratio and high quality. Also, VT
There is no memory installed on the R side, so that's all.
-r R can be configured into a small size.

FIG. 3 shows a block diagram of a second embodiment of the present invention, and in the figure, the same components as in FIG.

In the second embodiment, the VTR (till) is controlled by various circuits installed on the video printer side, and the operation is similar to that of the embodiment shown in FIG. 1, so we will explain it below. omitted.

Effects of the Invention According to the present invention, the desired frame can be reliably printed 7 times a day, and what is written in the regenerated shade is lint out 1 time, so the signal-to-noise ratio is good and high quality is achieved. The printing plate 1~ is long, and the printing plate 1) is placed on the video printer side, so there is no need for a printing plate on the VTR side, making the V plate 12 as small as possible. Can be configured.
