BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video recording / reproducing control device suitable for use when leaving a message to a family member when going out, for example.

[0002]

2. Description of the Related Art For example, when leaving a message to a family member when going out, if the message is left as an image and a voice, the message can be left extremely accurately. However, in order to leave the message in the form of video and audio in this way, in the conventional device, for example, a video camera integrated with a VTR is fixed toward itself, and this device is set in the shooting mode to record the video and audio of the message. It is not easy to implement.

Also, when viewing a message left in this way, even if a video camera with a built-in VTR and a liquid crystal monitor attached thereto is used, the VTR of this device is used.
After rewinding, the complicated operation such as switching to the reproduction mode is required, and the operation cannot be easily performed especially for the elderly and young children.

[0004]

This application has been made in view of the above-mentioned problems, and the problem to be solved is complicated in the conventional device when the message is left as video and audio. It was required to perform various operations and could not be easily executed.

[0005]

Therefore, in the present invention, a video recording / reproducing control device is formed to which a video device in which an imaging unit and a recording / reproducing unit are integrated is connected, and at least a recording operation unit is provided in this device. The reproduction operation section and the stop operation section are provided so that a message can be left and the message can be viewed only by operating these operation sections.

[0006]

According to this, the message of the image and the voice can be left by an extremely simple operation, and the message can be viewed by an extremely simple operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS To explain the present invention with reference to the drawings,
FIG. 1 is a block diagram showing a system of an example of a message device to which a video recording / reproducing control device according to the present invention is applied. This Figure 1
In, the illustrated message adapter 1 is the video recording / reproducing control device of the present invention. The video device 2 is, for example, a VTR-integrated video camera equipped with a liquid crystal monitor, and includes, for example, an imaging unit 21, a display unit 22, and a recording / reproducing unit 23 (not shown).

By placing the image device 2 on a predetermined portion of the message adapter 1, for example, an EZ is established between the two.
The control system is formed by a bidirectional communication format called general-purpose LANC communication, which is connected by the connections 11 and 24.

That is, the microcomputer (message microcomputer) 12 in the message adapter 1 and the control circuit (mode controller) 25 in the video device 2 are connected by LANC communication. Then, for example, information on the operating state (recording, reproduction, power on / off, etc.) and internal information (counter value, etc.) is transmitted from the video device 2 side, and the message adapter 1 determines the next operation based on the information, The operation command is transmitted to the video device 2 side.

FIG. 2 shows the appearance of the message adapter 1. For example, the message adapter 1 has five key switches 13, 14 for "shoot", "see", "stop", "clear", and "use / not use". 15, 16, 17 are provided. Further, for example, five message number display LEDs 18 are provided. Further, the above-mentioned E is provided on the upper surface of the message adapter 1.
Z connection 11 is provided, a video output terminal (not shown) on the back, and an AC adapter DK on the side
Connections (not shown) and the like are provided.

In the basic operation, first, when the "shoot" key switch (recording operation section) 13 is operated, the device 2 is turned on in the camera mode regardless of the position of the power switch of the image device 2. The state is set, and the shooting and recording of the message are started. In addition, the above-mentioned message number display LE
Display according to the number of messages recorded in D18 is performed.

Next, when the "stop" key switch (stop operation section) 15 is operated, photographing and recording of the above message are stopped. This completes the recording of one message and shifts to the power-off standby state. In addition, even when an operation is performed during message reproduction, which will be described later, the reproduction is terminated and the standby state is entered.

Further, when the "see" key switch (reproduction operation section) 14 is operated in the standby state, it is returned to the head position of the above-mentioned recorded message, and reproduction is performed from there. At this time, the message number display LED 18 blinks, and the number of the message being reproduced is displayed.

When the "clear" key switch 16 is operated in the standby state, the internal message information (the number of records, the recording position, etc.) regarding the recorded message is erased and the initial state is set. Further, with the "use / not use" key switch 17, the message operation is stopped when the key switch 17 is set to "not use". When the "use" is switched to the "not use", the same processing as the operation of the above-mentioned "clear" key switch 16 is performed.

Further, FIG. 3 shows the configuration of the power supply system.
That is, in the message adapter 1, power is supplied by, for example, an AC adapter and a built-in battery of the video device 2 described above. In this case, switching depends on, for example, the video device 2 side, and the adapter 1 side only receives a part of the power supply.

Therefore, in order to save the message information (the number of records, the recording position, etc.) even when there is a power failure, a backup system as shown in FIG. 3 is constructed. That is, in the figure, the power supply of the microcomputer (message microcomputer) 12 in the above-mentioned message adapter 1 is separated from the above-mentioned power supply path 30 via the diodes 31, 32, and a large-capacity capacitor is provided in the power supply path of this microcomputer 12. Three
3 are connected.

Therefore, the charge of the capacitor 33 secures the power source of the microcomputer 12 during a power failure. The reset IC 34 compares the potentials of the power supply path of the microcomputer 12 and other power supply paths. When a power failure is detected, the microcomputer 12 is shifted to the low power consumption mode, and when the power failure is restored, the interrupt is returned to the normal mode again. Processing is performed.

The signal from the set confirmation switch 35 when the image device 2 which will be described later is removed is the microcomputer 1
2 is supplied to the interrupt terminal. That is, since the message adapter 1 is not allowed to operate when the video device 2 is not connected, this set confirmation switch 35
The presence or absence of the video device 2 is detected by.

In this case, when the video device 2 is detached from the message adapter 1, the above-mentioned message information (the number of records, the recording position, etc.) becomes invalid, so that the microcomputer 12 cannot be reset by an interrupt. Done. Since this reset control must be performed even during a power failure, the signal from the set confirmation switch 35 is sent to the microcomputer 12 as described above.
Is provided to the interrupt terminal of.

The reset control by the interrupt is distinguished from the erasure of the message information (the number of records, the recording position, etc.) by operating the "clear" key switch 16 described above. This is the same as the operation of the "clear" key switch 16 when the "use / not use" key switch 17 is switched from "use" to "not use". This is to prevent the inconvenience that the reset control is performed when the key switch 17 is inadvertently switched.

Further, in the power mode of the message adapter 1, there are the following four power states. backup,
Standby state, video device power on, video device power off. The standby state here is the connection of the video device 2 or the "use" of the key switch 17 of "use / not use".
It is in the state of waiting for switching to.

In the LANC format described above, the LANC power can be supplied to the external device (message adapter 1) only when the power of the video apparatus 2 is turned on. It is possible to determine the on / off state (state) of the power source of No. 2. Furthermore, the transition of these power supply modes is shown in FIG.

The message adapter 1 has nine internal modes as shown in Table 1. In Table 1, “stop message (CAM)” is a mode in which the video device 2 is stopped in the camera mode for the reason described later.

[0024]

[Table 1]

These internal modes are basically generated by operating each key switch. The operation command transmitted to the video device 2 side is basically generated by these internal modes. This is because the operation command cannot be executed unless it goes through some modes such as stop → rewind and play → stop → rewind.

The following control is performed by utilizing these internal modes.

That is, when the "shoot" key switch 13 is pressed, the internal mode is set to "message shooting". When the power is off, first turn on the power. The video device 2 is set to the forced camera mode. Send the zoom wide command (fastest) for a fixed time. Increase the number of messages by 1. Start shooting and recording.

It is to be noted that since it is not known where the zoom position is at the time of the very first message, it is performed.
Note that this time counting is not performed during the transition. This is because there are times when commands are not accepted due to power transitions.
This is because the time that must be sent varies.

Next, when the "stop" key switch 15 is pressed, first, when the "message recording" mode is pressed, the internal mode is set to "message stop (CAM)". Save the counter value. Send a power off command. In other cases, set the internal mode to "stop message". Send a power off command.

The "message stop (CAM)" mode is
The power of the video device 2 is turned off while keeping the video device 2 in the camera mode, whereby the video device 2 slightly rewinds the tape to compensate for so-called splicing. Therefore, this processing is not performed in modes other than the "message recording" mode.

Further, when the "view" key switch 14 is pressed, the following processing is performed. "See" here
The key switch 14 is basically effective in the "message stop" mode and the "message look" mode.

Therefore, when the message is pressed in the "stop message" mode, the internal mode is set to "return message". Put the rewind command in the command waiting buffer. As a result, the first message is rewound to the beginning and reproduced.

When pressed in the "view message" mode, the internal mode is set to "pause message". Put the rewind command in the command waiting buffer. As a result, the message being reproduced is rewound to the beginning and reproduced. After that, the first message is also rewound to the beginning and played back, and when the message is completed, a power off command is transmitted to enter the standby state.

Further, when the "clear" key switch 16 is pressed, when the internal mode is "stop message" or "stop message (CAM)", a reset is applied to erase all message information. However, the tape is not rewound.

Further, in the above-mentioned message adapter 1, the processing when the counter is reset in the video device 2 is performed as follows. That is, since the message adapter 1 recognizes the message position from the information of the counter value, the operation becomes impossible when the counter is reset. Therefore, when the counter is reset, the message adapter 1 also needs to be reset.

However, in the LANC communication described above, the information that the counter reset key is pressed is not transmitted.
Therefore, if the counter value is 00:00:00 and the difference between the current counter value and the counter value one vertical period before is 3 seconds or more, the reset is determined and the message adapter 1 is reset. There is.

Further, in the above message adapter 1,
Even if the image device 2 ejects, the message information up to that point becomes meaningless. Therefore, also in this case, it is necessary to reset the message adapter 1. However, also in this case, in the VTR mode of the LANC communication described above, the distinction between no tape and eject is not transmitted.

Therefore, for example, if the reset is applied when the VTR mode transits from "other than eject" to "eject", the mode transits from "initial" to "eject" when the system is started without a tape. Will be reset. Therefore, if the above-mentioned "other than eject" is changed to "initial or other than eject", this time reset will not be applied if the message is ejected while waiting by "stop message".

On the other hand, in addition to the condition that the number of messages is included in the mode other than the "message recording" mode and the eject condition is added, a reliable reset can be performed.
The "shooting" mode itself is reset by applying a reset when the above-mentioned "other than eject" transits to "eject". Thereby, for example, when an eject is performed without a tape, an operation such as turning off the power after displaying a warning is performed.

FIG. 5 shows the PAD of the main routine process.
The figure is shown. In FIG. 5, a represents an iterative process, b represents a branch, and others represent processes performed. The processing is performed in the order from top to bottom and left to right of the drawing.

FIG. 5 shows a time chart of the operation at the time of "taking a message". The system controller status in the figure is. Used to forcibly switch power to camera / VTR. In addition, the LED blinks to inform the operating state until recording is started or while waiting for a message.

Further, FIG. 6 shows a time chart of the operation at the time of "looking at a message". It should be noted that in the figure, the date / time is displayed using a data code as the message time stamp.

Therefore, in this device, when leaving a message in the form of video and audio, a complicated operation is required in the conventional device, which cannot be easily executed. A video recording / playback control device to which the video device described above is connected, and at least a recording operation unit, a reproduction operation unit, and a stop operation unit are provided in this device, and a message is left only by the operation of these operation units, By making this message visible, it is possible to leave a video and audio message with an extremely simple operation, and also to see this message with an extremely simple operation.

Thus, according to the above-described video recording / reproducing control device, the video device in which the imaging section and the recording / reproducing section are integrated is connected, and at least the recording operation section and the reproduction operation are provided in the apparatus for controlling the operation of the video apparatus. Section and a stop operation section are provided, and when the recording operation section is operated, a control signal for setting the video device to the photographing recording mode is formed, and information on the number of times recording is performed is stored in the recording medium, and the stop When the operation unit is operated, a control signal for stopping the video device is formed, position information of the recording medium of the recording / reproducing unit is stored, and when the reproduction operation unit is operated, the position of the head of the recording medium is operated. By forming a control signal for setting the video device to the playback mode from the video signal, it is possible to leave a video and audio message with an extremely simple operation, and to view this message with an extremely simple operation. One in which it is bet.

The structure of the above message adapter 1 is as follows.
For example, a VT with an LCD monitor, which is the video device 2.
It can be installed in an R-integrated video camera, but in that case it is difficult to add a new key switch for operation especially in a small device, and when included in the video device 2, the function itself is not provided. However, there is a possibility that it will be buried in other functions, and the adapter type as described above is adopted. This makes it possible to increase the size of the key switch.

Further, the above-mentioned device can be used not only as a message but also as a device for easy snap photography.
