Description

Detailed Description of the Invention

[0001]

The present invention relates to a camera-integrated VT.
Regarding R, the power is turned off especially by the recording pause timer etc.
It relates to the operation of turning on the power again after the operation.

[0002]

2. Description of the Related Art Some conventional camera-integrated VTRs have a so-called program AE function that allows a photographer to select an arbitrary mode so that optimum recording can be performed according to various photographing conditions. . Normally, this has several modes as shown in FIG. 4, and many are dial-shaped in consideration of operability.

On the other hand, although there are various structures of the power switch of the camera-integrated VTR, there is a three-position slide switch of the camera mode, the power OFF, and the VTR mode as shown in FIG. Here, the camera mode is a mode used at the time of shooting, and the program AE is also effective only in the camera mode. When the power is turned off, the power of almost all circuits is turned off, and the consumption of the battery can be prevented. The VTR mode is mainly used during playback. In addition to the power switch, the power is turned off even when the power switch is in the camera mode, mainly for the purpose of power saving during shooting.
Some are equipped with a switch that can be turned on (hereinafter referred to as a standby switch). FIG. 6 shows an example of the circuit configuration of the power switch in this case. Where 1
Is the above-mentioned 3-position power switch, 2 is a standby switch, 3 is the status of these switches on port 4,
5 is a microcomputer for reading the power supply mode and controlling the power supply mode. To explain the operation, first the position of the power switch is "O".
When it is in the position of "FF", both ports 4 and 5 are at "H" level and the microcomputer 3 judges that the power is off. When the position of the power switch is in the position of "VTR", the port 4 is
Becomes "L" and port 5 becomes "H", and this state is judged to be the VTR mode. Port 4 is "H" when the power switch is in the "camera" position, port 5 is "L" when switch 2 is closed depending on the state of standby switch 2, and this state is determined to be the camera mode. To do. If the switch 2 is open, it becomes "H" and this state is judged to be power OFF. That is, even when the power switch 1 is at the "camera" position, the power can be turned off by the standby switch. The power supply V _DD of the microcomputer 3 is supplied even when the main body is powered off. That is, even when the power is off, the states of the power switch and the standby switch are always read.

By the way, there is a dial in which the program AE switching dial and the power switch are integrated into one dial as shown in FIG. In this example, the dial has a total of 8 positions, and the camera mode has 6 positions, including the camera full auto mode and the program AE mode. The remaining 2 positions are power supply OF
F and VTR modes. FIG. 2 shows a configuration example of a camera-integrated VTR using this program AE switching / power switching dial (hereinafter abbreviated as dial).

In FIG. 2, reference numeral 6 is a lens, and 7 is an image pickup section for converting the light passing through the lens 6 into an electric signal. Reference numeral 8 is a camera signal processing IC for processing the electric signal, and 10 is a microcomputer for controlling the camera signal processing IC 8 according to various modes (program AE, etc.) of the camera. On the other hand, the video signal from the camera signal processing IC 8 is recorded by the recorder signal processing circuit 1
3 and is recorded on the recording medium (tape) 15 via the electromagnetic conversion block 14. Reference numeral 12 is a microcomputer for mechanical control and servo control of the recorder.
The tape 15 is driven by controlling the. The dial 9 and the standby switch 2 are connected to the microcomputer 11. Information from the dial 9 is input as a 3-bit binary code, for example. From this information, the microcomputer 11 communicates the camera mode, such as the type of the program AE, to the microcomputer 10 while communicating with the microcomputer 12. The power control of the microcomputer 11 is exactly the same as that described with reference to FIG. That is, the dial 9 is "VT
If it is in the "R" position, the VTR mode is set, if it is in the "OFF" position, the power is turned off. If it is in any other position, the power switch is turned on in the camera mode or the power off state.

By the way, the conditions for turning off the power are actually other than the above-mentioned conditions. When the recording pause state in the camera mode continues for a certain period of time, the power is automatically turned off to protect the head and tape. (This is called the recording pause timer). Also, the peripheral device connected to the main unit has a power switch, and when a power off command is sent by it, the power is turned off.
I do. Since the dial 9 and the standby switch 2 are absolute position switches, in order to turn on the power again from this state, some operation different from normal power-on is required. Therefore, conventionally, the standby switch 2 is once opened (power off position) and then closed again (standby position), or the dial 9 is once turned to the “OFF” position and then the desired camera mode (program AE) is set. Therefore, it was necessary to turn on the power. This operation flow is shown in FIG. At the time of START, the standby switch 2 is "closed" and the dial 9 is in the camera mode. Whether the standby switch 2 is changed from "closed" to "open" to "closed" in steps 11 and 14, or in steps 12 and 16
When the power dial 9 is operated in the order of “camera” → “OFF” → “camera”, the power is turned on in step 18 in the camera mode indicated by the dial 9. When the dial 9 is turned to "VTR" in steps 13 and 15, the power is turned on in the VTR mode in step 17.

[0007]

However, in the above-mentioned conventional example, when it is desired to turn on the power again after turning off the power by the recording pause timer or turning off the power by the instruction from the peripheral device, the shooting situation is considerably different from the previous turning on. In many cases, the camera mode (program AE) different from the one used before is set. Operation of the standby switch (closed →
All you have to do is open → close, but if you change the shooting conditions or want to change the camera mode, you have to turn the dial to the desired camera mode in addition to this operation, that is, operate the two operating parts. It is necessary and quite troublesome. It is possible to operate with only one operation part, that is, with the dial, but in this case, since it has to be turned to the "OFF" position and then turned to the desired camera mode, this operation is also troublesome.

As an actual example, when the recording pause timer turns off the power and then tries to resume shooting in a camera mode different from the camera mode before the power was turned off, the power is first turned on by pressing the start / stop button. The type that is turned on is not preferable because an image during mode transition is recorded while the setting is changed to a desired camera mode after the power is turned on. In addition, the power source is O
When N is reached, it is impossible to confirm what kind of image will be recorded.

According to another operation method, the power is turned on again by operating the standby switch from ON to OFF to ON, and then the camera mode (program A
Although the method of moving E) to a desired mode and pressing the start / stop button is adopted, there is a problem that the operation is troublesome and it takes time to start recording.

As described above, conventionally, many inconveniences occur when the power is turned on again when the power is cut off by the timer.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to easily turn on the power from a power-off state by a recording pause timer or from a power-off state according to an instruction from a peripheral device. Another object of the present invention is to provide a VTR with a built-in camera that can perform a desired mode quickly.

[0012]

In order to achieve the above object, the present invention detects the positions of a plurality of camera modes and power-off, VTR mode, etc. on an integrated switch, and the recording pause timer times out. When the switch is moved from the current camera mode position to another camera mode position during power off due to (time out) or power off operation of peripheral devices, it is detected and power is supplied in that camera mode. Turn on.

More specifically, the present invention constructs a camera-integrated VTR as described in (1) and (2) below.

(1) A switch in which a switch for switching a plurality of camera modes and a power switch are integrally formed,
When the recording pause time exceeds a predetermined time and / or when a peripheral device instructs to turn off the power, a power-off means for turning off the power of the camera-integrated VTR, and a power-off means for turning off the power. A camera-integrated VTR, comprising: a control unit that detects that the switch has been switched from one camera mode to another camera mode when the switch is on and turns on the power in the switched camera mode.

(2) The camera-integrated VTR according to (1), wherein the switch is switched by a dial.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to Examples.

[0017]

【Example】

(Embodiment 1) FIG. 1 is a camera-integrated VT which is Embodiment 1 of the present invention.
6 is a flowchart showing the operation of R ”, showing a flow of the operation of re-powering on after powering off due to timeout of the recording pause timer or after powering off by peripheral equipment. 2 is the same as that of the conventional example, the detailed description thereof will be omitted.
Has gone.

At the time of START in FIG. 1, the standby switch 2 is "closed" and the dial 9 is in the camera mode. First, the standby switch 2 is "closed" → "open" →
When the operation is "closed", the power is turned on in the camera mode indicated by the dial 9 in steps 1 and 4 (step 7) as in the conventional example. Step 2 is different from the conventional example in this embodiment. That is, when the standby switch 2 is left as it is and even one dial 9 is turned to another camera mode, the power is turned on in that camera mode. Further, if the dial 9 is always turned to "VTR", the power is turned on in the VTR mode (S3, S5, S6), as in the conventional example.

As described above, according to this embodiment, after the power is turned off by the video recording pause timer from the video recording paused state or after the power is turned off by the instruction from the peripheral device, the power is turned on again. For example, if you want to set a mode different from that before power off, such as auto mode before power off and sport mode after power on, do not move the dial to sport mode or move the mode position to the target sport mode. Even if you move one position, the power is turned on, you can immediately check the image to be shot, and then press the start / stop button to start recording, so restart the recording in any camera mode. The operations up to can be performed in the minimum number of times and in the shortest time, and since the image can be confirmed immediately, there is no failure Its effect on the use is large.

(Other Embodiments) In the first embodiment, the standby switch 2 is provided as an example. However, it is naturally possible to implement the case where there is no standby switch and only the power dial is provided.

In the first embodiment, the example using the dial has been described, but the structure is not limited to the dial, and there are no restrictions on the structure such as a slide type or a lever type, that is, switching of several kinds of camera modes and a power switch are integrated. If there is, it can be carried out similarly.

Also, the several types of camera modes need not be the program AE.

[0023]

As described above, according to the present invention,
Powering off due to the timeout of the recording pause timer or powering off according to an instruction to power off from a peripheral device
From this state, the power can be turned on in a desired camera mode with a simple operation.

Further, the present invention can be implemented at a low cost because the program of some microcomputers can be simply changed and there is no need to change the configuration from the conventional one.
