As a result, when you press the freeze button or print button in still playback mode, the tape is rewound a predetermined amount and then returns to standard playback mode, and the image displayed in still mode is captured, allowing you to accurately and easily capture the desired image. can be printed.

[Example code] Hereinafter, an embodiment of the present invention will be explained with reference to FIG.

In the figure, 1 is a magnetic reproducing or recording/reproducing device (
(hereinafter abbreviated as VTR), 2 is a video printer device. The VTR 1 includes a mechanical means 11 and a video signal processing means 1.
2. Control signal processing means 13. Servo control signal processing means 14, VTR system controller (hereinafter referred to as VT
(abbreviated as R system controller) 15, operation means 16, and frame control means 17. The mechanical means 11 also includes a rotary cylinder 30 equipped with a pair of video heads (not shown);
Control head 31, all-M erase head 32, capstan motor 33, pinch roller 34, tape cassette 35, take-up reel 36, supply reel 37, magnetic tape 3
8. Consists of a tension arm 39 and guide pins 40 to 43.

On the other hand, the video printer device 2 includes a control determination means 20, a memory signal processing means 21, a memory means 22, an adjustment means 23, a print signal processing means 24, a print mechanism means 25, a printer system controller (printer system controller) 26, and an operation means 27. and control signal input/output terminal 28
Next, in explaining the operations, the classification of operations for freezing and printing a desired image and the classification of frame selection methods for selecting a desired image will be clarified.

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

(A) In the VTR standard playback state, operating means 16 or 2
7, the direct method freezes and prints the image directly.

(B) While the VTR is in slow or frame-by-frame playback mode, select the image you want to print, then press the freeze or print button to import the selected image into the printer, and then print it.

Next, there are the following three frame selection methods for selecting an image desired to be frozen/printed.

In either case, the desired image is basically selected in units of frames (or fields) of the reproduced image, and the method is to detect the amount of tape movement associated with forward/reverse rotation of the tape.

(a) Control signal method: This method uses control signals recorded on a control track on the tape. To select a specific frame, the amount of tape movement is detected by counting playback control signals.

(b) FG method: FG (Frequency Generator) is generated in conjunction with the movement of the tape.
ator) signal to detect the amount of tape movement. In this case, it does not necessarily correspond exactly to the frame number of the image. Therefore, when used as an independent method, it is suitable for freezing/printing a specific image as a linked operation of an image selection operation. Furthermore, this method is very effective in preventing malfunctions when used as an auxiliary means for the control signal method (a).

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

Next, the operation when using the above methods (A) and (B) will be explained.

First, the above case (A) will be explained. First, VTRI
is in a normal standard playback state, and the magnetic tape 38 is being fed at a predetermined speed from the supply reel 37 side to the take-up reel 36 side in the direction of the arrow in FIG. Further, the signals reproduced from the magnetic tape 38 by a pair of video heads (not shown) on the rotating cylinder 30 are subjected to processing such as amplification and demodulation in the video signal processing means 2 to convert them into video signals (luminance signals and chroma signals or This reproduced video signal reproduced as a color difference signal is supplied to the printer device 2 via the terminal 17. To obtain such a reproduced video signal, the control signal reproduced by the control head 31 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 magnetic tape 38 at a predetermined phase. The capstan 33 is controlled and driven so that the reproduction control signal has a constant phase with the rotating cylinder 30. Note that FIG. 2 shows an example of track arrangement on the magnetic tape 38.

On the other hand, in the video printer device 2, the video signal input from the terminal 28 is passed through the memory signal processing means 21,
Directly as a composite signal, or brightness and color signals, brightness and color difference signals, or red (R) of the three primary color signals
, green (G), and blue (B) and supply them to the memory means 22. On the other hand, in response to a freeze command sent from the system controller 15 of the VTRI or a freeze command from the printer operating means 27, the printer system controller 26 controls the memory means 22.
outputs a freeze command to the camera and instantly stores the supplied image signal in memory.

The memory means 22 enters the read state immediately after the memory is completed, and the read image is displayed on the monitor (
(not shown). Thereafter, the operating means 16 or 27 receives a print command, and the read image is taken into the print signal processing means 24 according to the pixel order or line order to be printed, and after being converted into the data format to be printed, the print mechanism means 25
Printed at.

Here, the processing methods of the print signal processing means 24 and the printing mechanism means 25 have no influence on the gist of the present application, and include - plane sequential or line sequential printing for each color, dyes, pigments, thermal methods, inkjet methods, etc. Either 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.

Note that the memory means 22 is not limited to semiconductor memory, but may also include floppy means that directly stores analog signals,
Other recording media or other digitally recordable recording media may be used.

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 38.

Now, in the standard playback state period A), a freeze command is output at point P, and immediately after the image is captured into the memory means 22, a freeze completion signal is sent to the VTR system controller 15 of the VTRI via the terminal 28.101 to the printer system controller. 26. As a result, VTR system controller 1
5 outputs a stop and reverse command to the servo control means 14, rewinds the tape by several frames (period B), and then waits in a pause state (still reproduction state) (period C). Here, this pause state is canceled by the timer function in the VTR system controller 15 or by a print command signal from the printer system controller 26 in the printer device 2, and the tape 38 is unloaded (the tape 38 that was crimped on the rotating cylinder 30 38 may be in a detached state).

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 23.
will be displayed on the screen. When printing this memory image, a freeze command may be input from the operating means 27 of the printing device 2 or the operating means 16 of the VTR 1. However, there are many cases where the frozen image does not show the desired scene and it is desired to freeze a better image before or after the frozen image. In this case, for example, a play command may be input from the operation means 16 of the VTRI to cancel the pause state, or a freeze command or a dedicated pause release command may be input from 6.27 on the operation means to release the pause state. It may be canceled (point Q in FIG. 3). This allows the VTRI to display the previously played scene again and input a freeze command (point R) at the desired scene again. In addition, at point S, due to print commands, etc.
The tape 38 is in an unloaded state.

Next, a case will be described in which a still image to be printed is selected by slow motion or frame-by-frame advance as in case (B), and then frozen/printed.

In this case, a specific frame in a moving video is mainly frozen/printed. The operation at this time is explained in the fourth section.
This will be explained using the tape state diagram shown in the figure. First, while the VTRI is being played back (period A), an image desired to be printed is selected by slowing down or advancing frame by frame (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.

Freezing an image directly from a still state is not preferable from the viewpoint of image quality deterioration. First, a freeze command is input while the desired image is still reproduced (period C) (FIG. 4 PL). As a result, a freeze operation or a print operation is performed according to the following operation procedure. First, VTR1
The tape is rewound a small amount (period D) while counting (counting up) the tape rewound amount NB. Thereafter, standard playback resumes (period E), and the amount of tape movement at this time is counted (NF) in a countdown state.

Standard playback continues until the count value NF approaches NB (or until the count value of the up/down counter approaches O). After that, when the count value NF of the counter reaches a predetermined value NP (NP < NB) close to NB (Fig. 4 P2
), while maintaining the standard playback state, the freeze command is set to VT.
The RI outputs the screen to the printer device 2 and stores that particular screen in the memory means 22 in the printer 2. Here N
The purpose of setting P<NB is to output a freeze command several frames before the desired image arrives to correct the delay within the printer device. When the printer device 2 completes the memorization, it supplies a stop command or a reverse stop command to the VTRI. Thereafter, the printer device automatically or manually enters the printing state.

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.
Set I to standard playback mode. On the other hand, in manual printing, the user checks the frozen image, adjusts the image quality, and then inputs a print command.

Now, in the case of (B) above, there are three methods (A to C) described above as methods for freezing the selected image from the frame-by-frame advance or still state, and these will be explained below.

First, an embodiment of the control signal system (a) is shown in FIG. FIG. 5 shows one of the frame control means 17 in FIG.
This is an embodiment, and the tape movement detection means 1 is composed of a tape movement detection means 170 and a freeze control means 179.
Reference numeral 70 includes a counting means 171, a differentiating circuit 172, a decoding means 173, and a freeze command generating means 174.

Next, when a frame desired to be frozen is selected in FIG. 4, which describes the operation using FIGS. 4 and 6, a freeze command (or print command) is input from the operating means 16 (or 27) at Pl. This allows the VTR
The system controller 5 reverses the capstan 33 for only a few frame periods (period D), and then advances the tape in the forward rotation direction in a standard playback state (period E). At this time, in FIG. 6, the forward/reverse signal of the capstan 33 is inputted from the terminal 1701 and is supplied to the counting means 171, the differentiating circuit 172, and the freeze command generating means 174. Counting up/down (U/
D) It is input to the terminal and determines the counting direction. In other words, as soon as the capstan 33 is reversed, the forward/reverse signal is IjHjj
level, and the counting means 172 is switched to up-counting mode. On the other hand, the change of the forward/reverse signal to the It H11 level is detected by the differentiating circuit 172 and outputs a preset (ps) pulse to the counting means 171. At this time, the counting means 171 is set to the initial value (No), and simultaneously counts the control signal (hereinafter abbreviated as CTL signal) input during the reversal period. Thereafter, at the same time as the capstan 33 changes to the forward direction, the forward/reverse signal is inverted to lj L 7 levels, and the counting means 171 counts the CTL signal in the down direction.

Now, the counted value is a predetermined value NP
()No), the decoding means 173 outputs the count value N
P is detected and the pulse shown in FIG. 6d is output to the freeze command generating means 174 at the next stage. As a result, the freeze command generating means 174 generates the freeze pulse shown in FIG. 6C. Further, the next-stage freeze control means 179 receives freeze operation commands and recording/reproduction commands from the VTR system controller 5 and outputs freeze signals and freeze command signals. By this freeze command signal, the control signal processing means 13
(FIG. 1) stores a desired image in the memory means 22 by a freeze signal.

In the above description, the count value NP for outputting the freeze command is set to be different from the initial value No, so that NP>No.

In other words, the number of CTL signals during reverse rotation is NB, and the number of CTL signals until outputting the freeze command during subsequent forward rotation is N.
If F, 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 freeze command signal is output with a margin of several frames. This is taken into consideration.

Next, an embodiment of the above-mentioned (b) FG method is shown in FIG.

This figure shows an embodiment of the servo control means 4 and frame control means 17 in FIG. In FIG. 7, parts having the same functions as those in FIGS. 1 and 5 are designated by the same numbers. In FIG. 7, the servo control means 14 includes a servo control circuit 141, a rotation direction detection means 142, and a waveform shaping circuit 143. Further, the frame control means 17 is composed of a tape movement amount detection means 170, a freeze control means 179, and a recording medium movement amount detection means 178,
This recording medium movement amount detecting means 178 is connected to the counting means 17.
81, a differentiating circuit 1782, a decoding means F83, and a freeze pulse generating means 1784. This embodiment is particularly effective in the case (B) and case (C) described above, and is shown in a configuration that can be used in conjunction with the control signal system in FIG. Of course, independent use is also possible. Now, the usage state is the freeze operation and print operation of a specific image from frame-by-frame playback in FIG.

Next, the operation will be explained. First, the servo control circuit 141
The capstan motor 33 is controlled and driven by a start/stop signal, a forward/reverse signal, and a high/low speed command signal from the R system controller 15.

On the other hand, a frequency generating means linked to the rotation of the capstan motor 33 generates a feedback signal F G (Frequency) proportional to the amount of tape movement, and outputs a feedback signal to the servo control circuit 141 and the rotational direction detecting means 1.
42. Here, the servo control circuit 141 is constituted by speed control or phase control means used in general VTRs. Further, the rotation direction detection means 142 is also a VTR.
This is a forward/reverse direction detection means using a two-layer FG signal, which is used in In other words, when the capstan motor 33 rotates to advance the magnetic tape in the forward direction (forward rotation), its output is at the PI L'' level, for example, and when it rotates in the opposite direction, it is at the IIHII level. In the case of FIG. In this case, the forward/reverse rotation detection signal becomes "H" level.

This FG double signal and forward/reverse detection signal is connected to terminal 1405.1.
It is supplied to the frame control means 17 via 704.

The operation of the recording medium movement amount detecting means 178 will be explained below using the case shown in FIG.

At PL in Figure 4, when the capstan motor 33 reverses, the output of the rotation direction detection means 142 is reversed to the IT H'' level.At this time, the recording medium movement amount detection means 178
In the 0 operation, the differentiating circuit 1782 first detects (differentiates) the rising edge of the forward/reverse rotation detection signal, and presets the counting means 1781 to, for example, No=O. At the same time, the counting means 1781 enters the up mode, and as the capstan motor 33 progresses in reverse, the count value is increased. When the tape is reversed a few frames, the VT
The servo control means 1 is activated by the forward/reverse command from the R system controller 15.
4 rotates the capstan motor 33 in the normal rotation direction and enters the standard playback state (reverse to Fig. 4 and count means 1
781 enters the down mode, and its count value is decreased by subsequent FG 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=O
) 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 1783 outputs the detection pulse shown in FIG. 8d to the next-stage freeze pulse generating means 1784. As a result, the freeze pulse generating means 1784 outputs the freeze signal shown in FIG. 8e using a forward/reverse signal or the like.

Here, the pulse phase of the freeze signal is output at a phase in which, for example, the count value of the counting means 1781 in the down mode rises at NP and falls at No. In other words, from the NP state in which the tape movement amount approaches No, the freeze control means 179 enters the preparatory operation, and the falling phase of the freeze signal represents the absolute desired image position to be frozen.

Here, the FG multiplied signal frequency (from several 100 Hz to several Hz) is a very effective signal for detecting the amount of tape movement;
There is no direct relationship with the phase of 30Hz or 25Hz). Therefore, it can only be used to detect the predetermined position of an image desired to be frozen, and is always used in combination with a CTL signal or a vertical synchronization signal in a reproduced video signal. Next, the above-mentioned time code 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, which is a method in which an address is recorded on all or part of a recorded image and then reproduced.

An example of this method is shown in FIG. In FIG. 9, the frame control means 17 is an address recording/reproducing means 1711.
, address storage means 1712 and address comparison means 17
13, each operated by a control signal from the VTR system controller 5.

Next, the operation will be explained. A playback video signal or a playback control signal is input through a terminal 1705 or 1701 and is input into address recording/playback means 1711. Here, the address is always detected during tape playback and is supplied to the next stage address storage means 1712 and address comparison means 1713. When an image desired to be frozen is selected by frame-by-frame forwarding or the like, a freeze command is input from 6 or 27 on the operating means. As a result, VTR system controller 1
A mark operation signal is input from 5, and the address number of the image is held in address storage means 1712. Thereafter, the tape is rewound by a small amount by the VTR Cisco King 5, and then enters the standard playback state. At the same time, the reproduction address from the tape and the storage address of the address storage means 1712 are constantly compared, and when a predetermined frame comes before, the address comparison means 1713 outputs a freeze signal.

Note that the address storage means 1712 described above has the ability to store multiple addresses. 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.

Kuyumatashita, extra bugs> Next, another embodiment of the present invention is shown in FIG.

In FIG. 1O, parts having the same functions as those in FIG. 1 are designated by the same numbers. 3 is a television, and a signal processing unit 301
．． It is composed of a CRT (cathode ray tube) 302, operating means 303, signal input/output terminals 304, and bus terminals 305. Further, the VTR 1 is comprised of an audio processing means 18, a tuner means 19, an audio head 44, a received signal input terminal 102, signal input/output terminals 103 and 105, and a bus terminal 104 in addition to the components shown in FIG. In addition to those shown in FIG. 1, the printing apparatus 2 includes a signal selection means 29, a signal input terminal 201. It is composed of a signal output terminal 202 and a bus terminal 203. Here, the bus terminals 104.2o3 and 305 are connected by the same cable.Next, the operation will be explained. First, the overall operation will be explained. A video signal selected by the tuner means 19 of the VTR 1 is supplied to the video signal processing means 12. On the other hand, in this video signal processing means 12,
The above-mentioned selected video signal is recorded on a tape, or a reproduced signal from the tape is processed. Further, the video signal processing means 12 switches between an external signal from the tuner means 19 and a reproduction signal from the tape and supplies the signal to the terminal 103. In the printer device 2, one of the video signals from the terminal 201 is supplied via the memory means 22, and the other is directly supplied to the signal selection means 29 at the next stage. In other words, the memory image or the input through image is output to the output end 202 of the printer device 2 . This output signal is supplied to the signal input/output terminal 304 of the television 3 at the next stage, and the signal processing means 3
01 and is displayed on the CRT 302.

On the other hand, the operation means 16, 27, and 303 of the VTR 1, printer device 2, and television 3 are each equipped with a remote control device, etc., and each device (
The basic operations of the VTRI, printer device 2, television 3) can be controlled.

In explaining detailed operations, means with the same numbers as in FIG. 1 perform the same operations. In other words, as in Figures 3 and 4, V
When a specific scene of the reproduced image of TR1 is frozen and printed on the printer device 2, the same operation as in Figure 9, @ is performed. However, the audio processing means 18 operates as follows. During normal tape playback, the playback signal from the audio head 44 is processed and supplied to the signal input/output terminal 103. - Mute the audio signal during six-speed variable playback or when freezing/printing a desired image as in the present invention. This operation will be explained using FIG. 11. FIG. 11 is a diagram with the audio mute state added to FIG. 4. In addition to variable speed playback (periods B and C), reverse rotation occurs after freeze command input Pl.

The mute state is maintained throughout the period of standard playback, freeze P2, and stop or re-reverse/stop. This mute state is controlled by the VTR system controller 15 and the frame control means 17.
This can be easily determined based on the signal from

Here, bus terminal 104. A control signal for a cable connecting 203 and 304 (hereinafter this cable will be referred to as a path line) will be explained. The configuration of the control signal on the pass line (hereinafter referred to as a bus signal) is composed of a series of data strings such as a C data section and an acknowledge section Ack.

Each data string is assigned a pulse length and transferred according to its specifications. For example, when a VTRI sends a freeze command to the printer device 2, a bus signal consisting of a printer custom code, a freeze command data code, and a leader pulse is sent. Printer device 2
When this signal is detected, an acknowledgment signal Ack is sent back to the VTR 1 according to the specifications.

At the same time, a freeze operation for the memory means 22 is started. Similarly, bus signals such as print commands, power on/off control, output signal switching control, etc. are transferred. If the receiving side cannot execute the command of the received data code, it does not return the acknowledge signal. For example, when a print command is received, if the printer device is in a state where it cannot proceed to print (out of ink paper, no print paper, etc.), the acknowledgment signal Ack@VTRI is not returned. Of course, these signals may also be transferred in combination. That is, when viewing the video output (tuner output, playback output, etc.) of the VTRI on the television 3, the printer device 2 does not necessarily need to be powered on. When you are watching the tuner output of the VTRI with the printer device 2 powered off and an image that you want to record on tape or an image that you want to print appears, you can issue a recording start command to the VTRI or a command to the printer device 2 using the remote controller described above. Power on/
Automatic recording or freezing is possible by transferring a freeze command. Therefore, each remote control device attached to each device (VTR, printer, television) is provided with a freeze key and a print key.

Note that in the above case, if the acknowledge signal is not detected, the transmitting side may be made to send the bus signal a predetermined number of times again. To check the busy state of the pass line, for example, it is detected that the line is at a "high" level for a predetermined period of time.

In the above embodiment, a system has been described in which a screen to be frozen/printed is captured from the VTR 1 to the printing device 2. However, when an image being viewed on the television 3 is captured to the printer device 2 or recorded by a VTRI, This can also be achieved using a similar operation.

Furthermore, in the above description, the image taken into the printer device 2 is assumed to be one screen, but the invention is not limited to this.

That is, by providing the memory means 22 in the printer device 2 with a plurality of frame memories, images before and after the freeze command can be stored in the memory means 22. Furthermore, by using a recording medium such as a video floppy that can continuously record analog signals,
It is possible to record several to several dozen images. In this case, as shown in FIG. 13, for example, after four scenes are frozen in succession, they can be displayed one after another on the television 3 and the desired screen can be printed. Alternatively, each of these 400 pages can be reduced to half the size (-4 of the area) and printed in four parts as shown in FIG. Of course, continuous multi-printing of 16 or 25 screens is also possible.

Further, although the description has been made using a VTR, a printer, and a television system as devices connected to bus signals, the present invention is not limited to these, and the device may be connected to, for example, a BS tuner or a video device with a single tuner.

〔Effect of the invention〕

As described above, a specific image of a series of images is selected by connecting a magnetic reproducing or recording/reproducing device, other video equipment, a printer device, an imaging means such as a television, etc. using a common bus signal.

By accurately importing this into the printer device, the desired image can be printed. In this case, unpleasant noises are muted by muting the sound during the operation period.

Furthermore, by providing memory means for a plurality of frames, it is possible to obtain a plurality of multi-prints, which improves usability.

Furthermore, by using the control signal method, the FG method, and the address method alone or in combination, it is possible to stably print a desired image without malfunctioning even at the joints of recorded images.

Therefore, according to the present invention, it is possible to accurately and easily select one specific scene in a continuous image from a magnetic reproduction or recording/reproducing device, import this image into a printer device, and print it later automatically or manually. We can provide video printer systems that can.
