Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a simultaneous image / audio transfer method for simultaneously transferring image data and audio data.

[Prior Art] In an image / audio simultaneous transfer method having a camera driving mechanism capable of controlling a pan direction, a tilt direction, and a ratio of a zoom lens by control from a terminal side via a communication network,
Conventionally, when a user enters a shooting prohibited range for prohibiting shooting in a range where shooting is not allowed, the transfer of image data and audio data in the shooting prohibited range is prohibited by stopping the camera driving mechanism.

[Problem to be Solved by the Invention] However, the simultaneous image and audio transfer method according to the conventional method described above can be realized when there is only one area where photography must not be performed. There is a drawback in that transfer of image data and audio data cannot be prohibited when the data reaches a portion.

[Means for Solving the Problem] In order to solve such a problem, an image / image
The simultaneous voice transfer method includes means for storing a range in which the camera must not shoot, and temporarily stops transferring image data and sound data when the shooting direction of the camera falls within a preset range. When the distance is out of the range, the transfer of the image data and the audio data is restarted.

[Operation] If the shooting direction of the camera falls within a preset range, the transfer of image data and audio data is temporarily stopped, and if it falls outside this range, the transfer of these data is restarted. As a result, even in the case where the range that must not be photographed extends to several places, if these several ranges are set in advance, transfer of image data and audio data within this range can be prohibited, and photographing can be performed again. When it is within the range, image data and audio data can be transferred.

Example Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a simultaneous image / audio transfer system according to the present invention. In the figure, 1 is a camera for image input, 2 is a camera driving mechanism, 3 is a microphone, 4
Is an image / audio output device such as a VTR, and 5 is an image / audio output device.
An audio switching device, 6 is a camera-side control device, 7 is a data conversion device, and 8 is a storage device. The camera 1 to the storage device 8 constitute a device on the camera side. On the other hand, the terminal device is configured as follows. That is, 9 is a display device for image reproduction, 10 is a speaker for audio reproduction, 11 is an input device, 12 is a terminal-side control device, and 13 is a data conversion device. A communication network 14 connects the camera-side device and the terminal-side device.

Next, Table 1 is a table showing the position information of the range that must not be photographed, which is stored in the storage device 8 in advance.
A state in which two locations in a range of 50 degrees to 80 degrees and a range of 120 degrees to 140 degrees are stored is shown.

Next, the operation of the simultaneous image / audio transfer system according to the present invention will be described.

Now, as shown in the figure, it is assumed that the camera-side device and the terminal-side device are connected via the communication network 14, and the storage device 8 has a plurality of pieces of position information of a range which must not be photographed in advance. Is set at the position of.

The image data from the camera 1 and the audio data from the microphone 3 are converted into digital data by the data converter 7 and transferred to the terminal device via the controller 6. The control device 12 in the terminal device receives the image and voice data converted into the digital data, and causes the data conversion device 13 to convert the data.
The converted image data is transmitted to the display device 9 and the audio data is transmitted to the speaker 10 for reproduction.

In this case, when camera position information for changing the shooting direction of the camera 1 is input from the input device 11 at any time, the camera position information is transmitted to the control device 12 and the communication network.
It is transferred to the control device 6 through 14.

The control device 6 having received the camera position information controls the camera driving mechanism 2 to obtain the current position, calculates the position information specified by the terminal device and the current position information, and stores the calculation result and the storage result. The camera drive mechanism 2 is operated when the calculated value does not fall within the non-capable range in the storage device 8. If the calculated value falls within the range where photographing is not allowed, the image and sound data to be transferred to the terminal side device by controlling the image and sound switching device 5 is transferred to the image and sound output device 4. Switch to data.

Then, after switching the image and audio data to be transferred to the terminal device to the data from the image / audio output device 4, the control device 6 in the camera device continuously receives the camera position information from the terminal device. Although the current position information of the camera and the camera position information received from the terminal device are calculated, if the calculation result is out of the range in which photographing is not required and stored in the storage device 8, the image The audio switching device 5 is controlled to return the image and audio data to the original image and audio data from the camera 1 and the microphone 3 and transfer these data to the terminal device.

In the above description, the method of performing all the operation of the camera position information on the camera side has been described. However, the three devices of the image / audio output device 4, the image / audio switching device 5, and the storage device 8 are installed on the camera side. Instead of providing the information to the terminal device, the position information that must not be taken by the terminal device is managed by transferring the position information of the camera 1 to the terminal device via the communication network 14 each time the camera 1 moves. It is self-evident that functions equivalent to the above can be realized.

Further, in the present embodiment, the case where there is a plurality of shooting prohibited ranges only in the pan direction has been described, but it is easy to set the shooting prohibited range in which the tilt direction and the ratio of the zoom lens are combined in the storage device 8. Thus, it is obvious that any combination of shooting prohibited ranges can be realized by the present invention.

Table 2 shows the state in the storage device 8 when a plurality of shooting prohibited ranges are set in the pan direction and the tilt direction.

In Table 2, the movable range of the camera driving mechanism 2 is 0 ° ≦ pan direction <360 ° (1) −90 ° ≦ tilt direction <+ 90 ° (2).

In Table 2, in the range of 50 degrees to 80 degrees in the pan direction, the entire angle in the tilt direction, ie, from -90 degrees to +90 degrees, and in the range of 120 to 140 degrees in the pan direction, the entire angle in the tilt direction, ie, -90 degrees. In the range from 90 degrees to +90 degrees and the pan direction from 200 degrees to 210 degrees, the state in which the shooting prohibited range is set at all three angles in the tilt direction, that is, from -90 degrees to 0 degrees is shown.

As shown in Table 2, three shooting prohibited ranges
Is set in the storage device 8, the same operation as described above is performed. That is, transfer of image data from the camera 1 and sound data from the microphone 3 is prohibited in the photographing prohibited range 1 to 5 and image and sound data from the image / sound output device 4 are transferred to the terminal device instead. In addition, the image data of the camera 1 and the microphone 3
Is transferred to the terminal device.

As described above, an object of the present invention is to enable simultaneous transfer of images and voices even when a range that must not be photographed extends to a plurality of locations. For this reason, a plurality of photographing prohibited ranges can be stored. A storage device 8 is provided, and when the camera shooting direction enters the shooting prohibited range stored in the storage device 8 while the camera 1 is operating, the camera 1 does not transfer the image and audio data from the camera side but determines in advance. In this case, the image and audio data are switched and transferred, and when the image returns to the photographable range again, the image and audio data from the camera are transferred.

As described above, according to the present invention, there is an advantage that even when there are a plurality of non-shooting ranges, images and sounds can be transferred simultaneously beyond the shooting prohibition ranges. It has the effect.

[Effects of the Invention] As is apparent from the above description, the simultaneous image / sound transfer method according to the present invention provides a method for transferring image data and sound data when the shooting direction of the camera falls within a preset range. The transfer is temporarily stopped, and when the data goes out of this range, the transfer of these data is restarted. With this arrangement, the transfer of image data and audio data can be prohibited within this range, and when the image returns to the photographable range again, the image data and audio data can be transferred again.
