Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video printing system capable of holding in a memory and printing a desired image of reproduced video No. 100 from a magnetic recording/reproducing device.

[Conventional technology]

A conventional device, as described in Japanese Patent Application Laid-Open No. 56-64884, is a device that captures one screen of an input video signal into a frame memory and prints it. Only images were provided.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration the function of selecting a specific image from a series of continuously reproduced images, accurately importing it into a printer, and printing it. There was a problem in that it was not possible to view a single scene accurately and easily.

The object of the present invention is to accurately and easily select one specific scene in a series of images from a magnetic recording/reproducing device and import this image into a printer device. The purpose of this invention is to provide a system that can print automatically or manually after n8.

[Means to solve the problem]

In order to achieve the above object, a means for detecting the amount of tape movement is provided so that the selected image can be accurately input into the printer.

Furthermore, in order to automatically import a plurality of specific images into a printer device in sequence, a freeze mark is recorded on the recording medium of the reproduced image source.

Furthermore, in order to maintain compatibility with other magnetic recording and reproducing apparatuses, mark erasing means is provided for automatically erasing the 7-lead mark after printing is completed. Furthermore, in order to enable stable image capture even when selecting a specific image near the recording seam on the recording medium, we have developed both a signal generated in conjunction with tape movement (rotation of the capstan) and a control signal on the tape. The position of the image is detected by O. [Operation] The tape movement amount detection means operates to accurately detect the amount of rewinding and the forward direction of the tape. Therefore, when you press the freeze button in the playback state, the tape is rewound a predetermined amount and then enters the standard playback state, and a freeze mark is recorded at the tape position of the image displayed in the still state, or a freeze mark is recorded on the printer device. Since the image is captured, the desired image can be printed accurately and easily.0 [Embodiment] An embodiment of the present invention will be explained below with reference to FIG. 1.

In explaining the missing number operation, we will clarify the classification of the operation side for freezing and printing a desired image and the frame selection method for selecting and freezing a desired image.

First, the following three methods can be considered as operation methods.

Prisoner When the VTR is in standard playback mode, use operating means 16 or 27.
Direct method that freezes and prints images directly.

(B) Area mark method in which area marks are recorded in advance at several locations when printing is desired in standard VTR playback conditions, and then a desired image near the marked area is selected and frozen/printed.

(C) When recording VTRM, record a frame mark on the specific frame image you want to freeze/print, and
Record a few scenes fc g *N '''C name・After that・
Frame mark method that freezes and prints sequentially automatically or manually.

Among the above three methods, the direct method is suitable for manually freezing/printing still images one after another. In addition, in the area mark method B, the mark is recorded on the image you want to print while playing back the entire scene, and after checking all the scenes8, high-speed (search) playback (
(forward rotation and reverse playback) to search for the desired area. Select 8 images of your choice near the desired area, freeze and print.

In this case, it is suitable for freezing a specific image of a slow moving image. In the frame mark method (C), a specific image desired to be printed is selected by slow playback or frame-by-frame playback at the same time as playback confirmation, and a frame mark is recorded on that image. After doing this for several pages gJ, all the marked images are automatically (or manually) printed. This method is particularly effective when selecting a scene with noticeable movement.

There are the following six frame selection methods for selecting a desired image to be printed. In either case, basically the frame (or field) of the reproduced image
The desired image is selected in units of 2.
This is a method for detecting the amount of tape movement associated with reversal.

(b) Control signal method: Control track on the tape (This is a method that uses the recorded control signal. Freeze marks corresponding to the above area marks and frame marks are recorded on this control track. For selection, it is used to select a 0 mark recording frame and to select a frozen image by detecting the amount of tape movement rljJ by counting playback control signals.

(0) FG method: Frequency generator FC (Frequency Generator) generated in conjunction with tape movement.
(tor) The amount of tape movement is detected by counting the signals. In this case, it is difficult to record and reproduce the mark, and it is effective when selecting a specific image in the vicinity because it does not necessarily correspond exactly to the frame number of the image. This is suitable for freezing/printing a specific image as an operation. Moreover, this method is very effective in preventing the rattling motion when used as an auxiliary means for the control signal method (a).

(c) Time code method: This is a method in which a frame number is written on every image, and the desired image to be frozen is selected according to this frame number. By combining the above methods (a) and (b) with the above method, malfunctions can be almost completely prevented.

Next, the operation when using the above method will be explained.

First, the case (4) above, where there is no freeze mark, will be explained. First, the VTR 1 is in a normal standard playback state, and the magnetic tape 58 is fed at a predetermined speed from the supply reel 57 side to the take-up reel 66 side in the direction of the arrow in FIG. A pair of video heads (not shown) perform processing such as amplification and demodulation on the magnetic tape 68, and reproduce the signal into a video signal (luminance signal and chroma signal or color difference signal). This reproduced video signal is supplied to the printer device 2 via the terminal 17. In order to obtain such a playback video signal, the control head 3
The control signal reproduced from 11 is amplified and shaped by the control signal processing means 13 and supplied to the servo control means 14. The servo control means 14 rotates the reproduction control signal in order to advance the magnetic tape 38 at a predetermined phase. The capstan 33 is controlled and driven to maintain a constant phase with the cylinder 3o.

Note that FIG. 2 shows an example of track arrangement on the magnetic tape 38.

On the other hand, in the printer device 2, the video signal inputted from the terminal 28 is processed by the memory signal processing means 21 into a luminance color difference signal or three primary color signals (red (1), green (0)).

It is separated into blue (B) and supplied to the memory means 22. On the other hand, in response to a freeze command sent from the system controller 15 of v'I'R1 or a freeze command from the printer operating means 27, the printer system controller 26 outputs a freeze command to the memory means 22, and instantly stores the supplied image signal. .

Immediately after the memory is completed, the memory means 22 enters the read state, and the read image is displayed on a monitor (not shown) via the adjustment means 258. Then the operating means 16 or 2
In response to the print command from 7, the read image is taken into the print signal processing means 24 in accordance with the pixel order or line order to be printed, and after being converted into the data format to be printed, it is sent to the print mechanism means 254. It is printed.

Here, the processing methods of the print signal processing means 24 and the printing mechanism means 25 do not affect the gist of the present application, and include - surface-sequential or line-sequential printing for each color, dye/pigment, thermal method, inkjet, etc. Any method may be used. In the following description, a sublimation dye thermal transfer method using a three-color sequential thermal line head will be described.

Now, the operation of the VTR 1 immediately after the printer device 2 records an input image in the memory means 22 will be explained using the tape state diagram shown in FIG. 3. In FIG. 3, the horizontal axis represents the flow of time, and the vertical axis represents the amount of forward movement of the tape 58.

Now, in the standard playback state (period A), a freeze command is output at point P, and an image is captured into the memory means 22. Immediately after this, a freeze completion signal is supplied from the printer system controller 26 to the VTR system controller 15 of the VTR 1.

As a result, the VTR system controller 15 outputs stop and reverse commands to the servo control means 14, and after rewinding the tape by several frames (period B), enters a pause state (still playback state).
Wait in (period C). Here, this pause state is VT
The tape 58 is unloaded by the timer function in the R system controller 15 or by a print command signal from the printer system controller 26 in the printer device 2. You can let it happen.

Now, the image stored in memory as described above (hereinafter also referred to as a frozen image) is displayed on a monitor (not shown) via the adjustment means 258.
will be displayed on the screen. When printing this memory image, the operating means 27 of the printing device IL2 or the VT
It is sufficient to input a freeze command from the operating means 16) of R1. However, there are many cases where the frozen image does not show the desired scene and you want to freeze a better image before or after the frozen image. In this case, the number is, for example, a VTR.
When canceling the pause state by inputting a reproduction command from the operating means 16 of 1, or by inputting a freeze command or a dedicated pause release command from the operating means 16 and 27 (as shown in Fig. 3), Point Q).

From this point on, the VTR 1 will again display the previous playback, and once again command freeze (point R) 8 at the targeted scene.
It can be done manually. Note that at point S, the tape 38 is unloaded due to a print command, etc. Next, as in case (B), record a 7-lease mark at the position of the scene you want to print or freeze during standard playback. A case where the image is then frozen/printed will be explained.

Here, 0&* will be explained using the flowchart in Figure 4.
The VTR 1 is in a standard playback state, and the tape 68 continues to move continuously. In this state, when the user comes to a scene that he or she wants to freeze or print, the user can use the operation means 16
．． 27, input a command to write the 7 Leeds mark.

As a result, a freeze mark is immediately recorded on the tape (P1 in FIG. 4).During this period, the VTR 1 continues to maintain the standard playback state. The tape (scene) progresses further,
When you reach the desired position to write the next freeze mark,
Input the freeze mark writing command again in the same manner. Such operations are repeated for each desired scene.

Now, once the freeze mark writing process is completed,
The user inputs a search freeze command using the operating means 16 or 27. (Fig. 4 P2) With this command, VT
R1 is reverse playback or reverse high-speed playback (search playback)
enter the state. Alternatively, after rewinding the entire tape once, it enters the standard playback or search playback state and searches for the freeze mark position. (Fig. 4, P3) When the first 7 series marks are detected, during forward rotation search, standard playback is resumed after stopping and reverse rewinding, and during reverse rotation search, normal playback immediately occurs after stopping. Shortly thereafter, the freeze mark is detected again (5g4, P4), and the image or the image immediately after is stored in the memory means 22 in the printer device 2. At the same time, vTRl enters a pause state and waits (4th
Figure P5).

Here, the image frozen in the above manner is an image that is generally close to the desired image, as described in method (B). Therefore, if you do not like printing a frozen image, select the images before and after it and issue a 7-degree freeze command to the operating means 16.
．． You can input from 27.

Afterwards - When the printing of the image is completed, the search state is entered again. At this time, the direction of search playback (forward/reverse) is VT.
It is stored by the R system controller 15 and the like.

Now, in the case of (゛) (I will explain the trick. In this case, we mainly freeze/print a specific frame in a moving video. The operation at this time is shown in the 70-chart in Figure 5. And use the tape state diagram in Figure 6 to explain 1.
First, VTRI is being played (period A) 6? - Select the desired image to be printed by slow motion or frame-by-frame advance (period B). In this case, since the content of the reproduced image varies greatly from frame to frame, the desired screen to be printed is selected using the slow or frame advance function. It is generally difficult to write a 7-res mark signal directly from a still state. First, a freeze mark writing command or a freeze command is input while the desired image is still reproduced (period C). (Figure 6 P1) (vJS figure P1) As a result,
Freeze mark writing or 7 reset operations are performed according to the following operating procedure. First, the VTR 1 rewinds the tape by a small amount (period D) while counting (counting up) the tape rewinding tNa. After that, standard playback resumes (
During period E), the tape transfer amount at this time is counted (NF) from the countdown state. Count [Nr approaches N, (
(or until the count value of the up/down counter approaches 0). After that, when the count value NF of the counter reaches a predetermined value NP 6c close to NB, in case B (4th
In the same way as in the figure), write the freeze mark for one frame.
Completed within a period of time. (P2 in FIG. 5) Alternatively, a freeze command is output and that particular screen is stored in the memory means 22 in the printer 2.

After that, when the print request screen is dusted again, an image is similarly selected by slow/frame-by-frame playback and a freeze mark is written. (Or input a freeze command and print 0) After these are completed, input a search freeze command in the same way as in FIG. 4 (P2 in FIG. 4), and then perform the freeze print operation in the same manner.

Here, there are two methods for the operation of the printer device 2. One method is automatic printing and the other method is manual printing. With automatic printing, the printing operation starts at the same time as the image freezes, and the VTR prints again at the same time as printing ends.
1 to the search playback state and enters the next freeze mark detection operation. On the other hand, in manual printing, the user checks the frozen image and inputs a print command if it is the desired image.

(P6 of Figure 4) If the image is not desired to be printed, the previous and previous images are checked again, the image desired to be printed is frozen, and then a print command is input. If there is no desired image to be printed, input the search freeze command again to return to the search playback state.

The above operations are continued until the end of the tape or until the operator inputs a stop signal.

Now, in the case of CB) and (C) above, the selected image is frozen or a freeze mark is recorded from the frame advance or still state. In this case, there are the aforementioned five methods (A to C), and these will be explained below.

First, an embodiment of the control signal method (a) is shown in FIG. FIG. 7 shows an embodiment of the frame control means 17 shown in FIG. 1, and is composed of a tape movement amount detection means 170 and a mark control means 179. Further, the tape movement amount detecting means 170 includes the counting means 171. Differential circuit 172. Deyoda means 175. It is composed of mark command generation means 174.

Next, the operation will be explained using FIG. 6 and FIG. 8. When the frame desired to be frozen is selected in FIG. Ru1,
As a result, the VTR system controller 15 reverses the capstan 63 for only a few frame periods (period D), and thereafter advances the tape in the normal rotation direction as a standard playback state. (Period E) At this time, the forward/reverse signal of the capstan 33 is inputted from the terminal 1701 as shown in FIG. The signal is supplied to a differentiation circuit 172 and a mark command means 174.

For the counting means 171, the signal is input to the count up/down (U/D) terminal to determine the counting direction.

In other words, at the same time as the capstan 53 is reversed, the forward/reverse signal becomes 1H" level, and the counting means 1718 switches to the up-count mode. On the other hand, the change of the forward/reverse signal to 1H" level is detected by the differentiating circuit 172, and the counting means 1718 switches to up-count mode. A preset (PS) pulse is output to the means 171. At this time, the counting means 171 is set to the initial value (Np) and at the same time counts 8 during the reverse rotation period A. At the same time, the forward/reverse signal is inverted to the 'L' level, and the counting means 171 counts the CTL signal in the down direction.Now, when the counted value reaches a predetermined value Np (>No), the dehood The means 175 detects the count value NP and outputs the pulse shown in FIG. Furthermore, the mark control means 179 at the next stage outputs a freeze mark signal and a mark command signal upon receiving a mark operation command and a recording/playback command from the VTR system controller 15.This mark command signal causes the control signal processing means 13 ( In FIG. 1), a freeze mark signal is recorded on the tape as described later.Furthermore, a desired image is stored in the memory means 22 by the freeze mark signal.

In the above description, the count value NP for outputting the mark command is made different from the initial value No, so that Np > No =:. In other words, if the number of CTL deviations during reverse rotation is NB, and the number of CTL signals until outputting the mark command during forward rotation is 8Np, then the relationship is NB>NF. This is because even if the freeze command is output at the same time as the desired freeze image is played back, the printer device 1 cannot immediately enter the freeze operation, so the mark command or freeze command signal is output with a few frames of time. An example of the above-mentioned (b) FG method, which takes into account the order of output, is shown in the ninth section.
As shown in the figure. This figure shows an embodiment of the servo control means 14 and frame control means 17 in FIG. In FIG. 9, parts having the same functions as those in FIGS. 1 and 7 are designated by the same numbers. In FIG. 9, the servo control means 14 includes a servo control circuit 141.degree. rotation direction detection means 142. It is composed of a waveform shaping circuit 143. The frame control means 17 also includes tape movement amount detection means 170. It consists of a mark control means 179 and a recording medium movement amount detection means 178, and this recording medium movement amount detection means 178 includes a counting means 1781. It consists of a differentiating circuit 1782, a decoder means 17, and a mark position generating means 1784.

This embodiment is particularly effective in the case (B) and case (C) described above, and can also be used independently as shown in the configuration shown in FIG. 7 in combination with the control signal system.

Now, the usage state is a freeze mark recording or freeze operation on a specific image from frame-by-frame playback as shown in FIGS. 5 and 6.

Next, operation 8 will be explained. First, the servo control circuit 141
The capstan motor 33 is controlled and driven by the start/stop signal, forward/reverse signal, and high/low operation command signal from the R system controller 15 in accordance with the flowcharts shown in FIGS. 4 and 5. On the other hand, a frequency generating means linked to the rotation of the cab stan motor 65 generates a feedback signal FG (Frequency) proportional to the amount of tape movement.
ency Generator) signal to the terminal 1405
Enter more information. The FG multiplied signal waveform shaping means 145 shapes the signal into a rectangular wave signal, which is then supplied to the servo control circuit 141 and the rotational direction detection means 142. Here, the mark control means 141 is controlled to #4 by speed control or phase control means used in a general VTRI. Further, the rotational direction detection means 142 is also a forward/reverse direction detection means using a two-phase FG signal used in a VTR. In other words, the rotation of the capstan motor 36 to advance the magnetic tape in the forward direction (forward rotation)
Sometimes, for example, the output is set to the 1L" level, and on the other hand, when the rotation is reversed, the output is set to the "H" level. In the case of FIG. Double signal and forward/reverse detection signal is at terminal 1405.170
4 to the frame control means 17.

The operation of the recording medium movement amount detecting means 178 will be explained below using the cases shown in FIGS. 5 and 6.

Now, in the PIG shown in Fig. 6, the capstan motor 53
When the rotation direction detecting means 142 reverses, the output of the rotation direction detecting means 142 is inverted to the 1H" level. At this time, the output of the recording medium movement amount detecting means 17
80, first, the rising edge of the forward/reverse rotation detection signal is detected (differentiated) by the differentiating circuit 1782, and the counting means 1781 is preset to, for example, N0=0. At the same time, the counting means 1781 enters the up mode, and as the capstan motor 53 progresses in reverse, the count value is increased. When the tape is reversed a few frames,
In response to the forward/reverse command from the VTR system controller 15, the servo control means 14 rotates the capstan motor 35 in the forward rotation direction to enter the standard playback state (r4E in the sixth diagram). At the same time positive/
The reversal detection signal is inverted to 'L' level, and counting means 1
781 enters the down mode, and its count value is decreased by the subsequent FG large input. Now, when the amount of tape approximately equal to the reverse rotation period is fed in the forward rotation direction, the counting means 1
The count value of 781 is a preset value (here No=0
) approach. This count value is always stored in the decoding means 178.
3, and a predetermined count value Np (Np > N
o), the decoding means 1785 outputs the detection pulse shown in FIG. Outputs the mark position signal. Here, the pulse phase of the mark position signal is such that the count value of the counting means 1781 in the down mode is NP.
It is output in a phase where it rises at NO and falls at NO. In other words, the amount of tape movement is not near ``''J Pata N・;
The ``control means'' is caused to perform a preparatory operation E, and the falling phase of the mark position signal represents the absolute desired image position to be frozen.

Here, the F'G signal (frequency is from several 100 dZ to several Kd)
z) is a very effective signal for detecting the amount of tape movement, but it has no direct relation to the control (CTL) signal or the phase of the reproduced video image (30h or 25h). Therefore, it can only be used to detect the predetermined position of an image desired to be frozen, and must be used in combination with a CTL signal or a vertical synchronization signal in a reproduced video signal.

Next, the above-mentioned time food method (c) will be explained.

- As a time code recording method, there is a method that uses a control track or a blanking period in a video signal, and this method records and reproduces the address of all or part of the recorded image.

An example of this method is shown in FIG. In FIG. 11, the frame control means 17 is the address recording/reproducing means 17.
11. It consists of an address storage means 1712 and an address comparison means 1715, each of which is operated by No. 7 from the VTR system controller 15.

Next, I will explain side works. A reproduced video signal or a reproduction control signal is inputted from the terminal 1705 or 1701 and is inputted to the n1 address recording/reproducing means 1711f. Here, the address is always detected during tape playback and supplied to the next stage address storage means 1712 and address comparison means 1716. When an image desired to be frozen is selected by frame-by-frame forwarding or the like, a freeze command is inputted from the operating means 16 or 27.

As a result, a mark operation signal is input from the VTR system controller 15, and the address number of the image is stored in the address storage means 17.
12f is held. Thereafter, the tape is once rewound a small amount by the VTR system controller 15, and then enters a standard playback state. At the same time, the playback address from the tape and the address stored in the address storage means 1712 are constantly compared, and when n1 predetermined frames have passed, the address comparison means 1713 outputs a freeze mark.

Note that the address storage means 1712 described above has a plurality of address storage capabilities. Therefore, after storing the address of a desired image to be frozen (or printed) from among all images, the images may be sequentially frozen (or printed).

Further, in the above time code system, the address storage means 1712 and the address comparison means 1713 may be provided in the VTR system controller 15.

FIG. 12 shows an example of a freeze mark recording and reproducing means for recording and reproducing freeze marks on the control track shown in FIG. 2 as one method for recording freeze marks from the standard reproduction state υ). This figure shows one embodiment of the control signal processing means 13. In FIG. 12, 130 is recording control (CTI) W number generation means.

161 is a freeze mark generation means, 132 is a freeze mark fiIII control means, and 133 is a recording CTL selector.

134 is a CTL recording switch, and 155 is a playback amplifier.

166 is a waveform shaping circuit, 157 is a freeze mark detection means, 138 is an erasure pulse generation means, and 169 is a mark control switch.

Next, the operation will be explained. First, CT during normal recording/playback
The operation of the LIM number processing means 13 will be explained with reference to FIG. Vertical synchronization signal in the video signal during recording (Figure 15a)
The frame signal b obtained by dividing the frequency by 8 (50 rlz in the case of the NTSC system, 25 Hz in the PAL system, etc.) is waveform-shaped by the recording CTI and m signal generation means 150, and the REC-CTL signal in FIG. 15C is generated. shall be.

This signal is connected to a CTL recording switch 154 via a C, TL selector 153. Here, in response to a recording command from the VTR system controller 15, the freeze mark control means 152 turns on the CTL recording switch 134, connects the recording CTL selector 165 to H1, and connects the recording CTL selector 165 to the control head 51 via the terminal 1551%.

This PB-CTL signal is a very small signal (10 mV or less), and the PB-CTL signal shown in FIG.
signal is amplified. Furthermore, the next stage waveform shaping circuit 136 generates a PB-CTL signal positive pulse VTR system controller 1.
Only the PB-CTL signal pressure or negative pulse is detected and output based on the positive/reverse signals from the PB-CTL signals. (Detects positive pulse during forward rotation) Then freeze mark detection means 1371
Here, only the freeze mark is extracted (the freeze mark is not recorded/reproduced in Fig. 15), and the periodic f, reproduction CTL (ia (Fig. 13 f) and freeze mark signal (Fig. 13 g) are extracted. However, as mentioned above, there is no mark signal).The reproduced CTL signal f) is separated and output.
The freeze mark signal g is supplied to the servo control means 14 and the control determination means 20f in the printer device tz, and the freeze mark signal g is supplied to the VTR system controller 15 and the control determination means 20.

Next, the case where the VTR 1 records and reproduces freeze marks during standard reproduction will be explained using FIG. 14. first@
In FIG. 12, it is assumed that the VTR 1 is in a playback state. (Period A in FIG. 14) At this time, the recording CTL selector 165 is set to L.
Also, the freeze mark generating means 151 generates the freeze mark signal shown in FIG. 154.

On the other hand, the mark command shown in FIG. 14 is inputted to the freeze mark control means 152 from the VTR system controller 15.

The freeze mark 88 is written only during the first reproduction CTL after inputting this mark command or during the reproduction CTL of the plate number pulse. (@Dotted line pulse in Figure 14 J) At this time, the ON/OFF of the CTL recording switch 154 is the waveform of the 14th factor J, and the ON period of level 1H" has a width that includes at least the 'L" period of the freeze mark. It is.

In addition, in Fig. 14, the phase of the 'L' pulse of freeze mark h is small (both RFC-CTL (Fig. f4 C)
Also, the 'H' period Tpa of the reproduction CTL (FIG. 14f) is TR<TPB<T.
F However, TF is related to the frame period. Also, in Figure 14, A! It exposes the magnetic field of the control track on the +2 tape.

Also, in the above explanation (well, freeze mark detection means 137
Although the freeze mark generation means 1518 has been explained as separate means, it can be understood from the phase relationship in FIG.
Both the reproduction CTL and the freeze mark are generated by being triggered by the PB-CTLf, and each signal may be generated by the same counter means or the like.

Next, we will explain the case where a freeze mark is detected on a tape with marks already recorded (Ki 14k) l').The PB-CTL in this case is the waveform of the 14th factor J and p,
The pulse train (period B) is partially discontinuous. This PB-

In this case, only the PB-CTL signal pressure pulse is shaped and output, and becomes No. 1g in FIG. 14m. After that, in the freeze mark detector &137, P B -01' L
It is separated into signal m and freeze mark P. As this separation method, PB-CTL is generated by a means such as a retriggerable monomulti. Freeze mark detection is achieved by connecting two monomultis in series, generating the gate pulse shown in Figure 14 (r), and detecting freeze mark P from a logic circuit (such as an AND gate) with shaped CTI and signal m. . Here, the rising phase of the gate pulse r (j
lJ edge) is within the pulse period of freeze mark h, and the falling phase (trailing edge) is between the freeze mark trailing edge and REC-CT.
It is set between the falling edges of the L signal C. Note that the pulse width of the freeze mark P may be arbitrarily changed depending on how the logic circuit is constructed.

From the above explanation, recording and detection of freeze marks is realized. Here, when a tape on which freeze marks have been recorded is reproduced on a VTR of another model, discontinuity in the control signal may cause disturbances in the servo system, resulting in disturbances in the reproduced image. Therefore, after the reproduced image is stored in the printer device 2 in the search freeze mode shown in FIGS. 4 and 5 and printed, the freeze mark is erased. This erasing method will be explained with reference to FIGS. 15 and 16. The reproduction CT L signal from the freeze mark detection means 157 is input to the erasure pulse generation means 168 . This playback CTL
The erase pulse shown in FIG. 16 is generated from the signal, and the mark control switch 169. Recording CTL selector 133, CTL
Control head 51 via recording switch 164
A bank is provided. At this time, the erase pulse is supplied to the control head over several frames before and after the freeze mark position. Further, the phase and width of the erase pulse are designed so that no noise pulse is generated within the gate pulse period.

In other words, as shown in Fig. 16, R is wider than the width of the gate pulse.
Design to be narrower than the EC-CTL signal. The write timing of the erase pulse will be explained with reference to FIG. FIG. 15 is a tape state diagram centered on image memory/printing and mark erasure due to freeze marks.

When the freeze mark is detected in period A) and point) M in the search mode, the tape is slightly reversed (period B). Immediately thereafter, the standard playback state is entered (period C), and a freeze mark detection operation begins. Then, by freeze mark detection (point P),
The memory means 22 in the printer device 2 automatically reproduces the image.
(Take this in.

At the same time, the VTR 1 reverses the tape by a small amount (period D) and enters a pause state. (Period E) The amount of tape movement or the number of frames reversed at this time is counted. After that, when printing is completed (point Q), the process moves to the next freeze mark detection operation. At this time, the aforementioned detection source freeze mark position can be determined by counting the amount of tape movement or the number of frames. Therefore, the freeze mark is erased by writing an erase pulse during several frame periods before and after this determined position (period F). At the same time as the mark erasure is completed (point R), the freeze mark detection operation by the search operation starts again (period G). When the freeze mark is detected again, the state returns to point M.

In the above description of FIG. 12, the waveform shaping circuit 166,
Freeze mark detection means 157. Although the freeze mark generating means 161 and the erasing pulse generating means 158 are described independently, the operations of each means are all synchronous with the reproduction control signal d#.

Therefore, by combining monostable multivibrators, a main digital counter and a decoding circuit, etc., it is possible to realize the same functional operation.

In all the embodiments described above, operation buttons for instructing mark recording/reproduction operations and operations for loading selected images into the memory means 1 are provided on the operation means 16 on the VTR 1 and the operation means 27 on the video printer 2, respectively. has been
The above operation can be controlled from either operating means.

Further, the operating means 27 of the video printer 2 has a memory button for directly importing the area input into the memory means 22f, and this memory button may also be used as the above-mentioned freeze command button.

〔Effect of the invention〕

According to the present invention, it is possible to select a specific image to be printed from a series of images from a magnetic recording/reproducing device, record a freeze mark on it, or accurately and easily import this image into a printer device. This has the effect of realizing an easy-to-use video printer system.

In addition, after recording freeze marks on all the images you want to print, it is possible to print them automatically and continuously.
This has the effect of reducing wasted time.Furthermore, after this automatic continuous printing, the 7 Lease mark is automatically erased, so there is no loss of compatibility of tapes, etc.

Further, by using both the control signal method and the FC method, it is possible to stably print a desired image without malfunctioning even at the joints of recorded images.
