Abstract

PURPOSE:To inhibit data transfer even when several ranges in which pickup is inhibited exist by stopping once picture and audio data transfer when a pickup direction of a camera enters a preset image pickup inhibit range and restarting the image pickup when the direction is deviated from the above range. CONSTITUTION:The system is provided with a means 8 storing a range in which image pickup by a camera l is inhibited and when the image pickup direction of the camera 1 enters the preset range, the transfer of a picture data and an audio data is once stopped and when the camera 1 is deviated from the range, the transfer of a picture data and an audio data is restarted. Thus, even when several image pickup inhibit ranges exist, the transfer of a picture data and an audio data is inhibited in the ranges by presetting the several ranges and when the camera enters again the image pickup enable range, the transfer of a picture data and an audio data is allowed.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an improvement in a simultaneous image/audio transfer system that transfers image data and audio data simultaneously.

[Prior Art] In a simultaneous image/audio transmission system that has a camera drive mechanism that can control the panning direction, two tilting directions, and the zoom lens ratio under control from the terminal side via a communication network, areas that must not be photographed Conventionally, when a camera enters a photography-prohibited area for prohibiting photography, the camera drive mechanism is stopped to prohibit the transfer of image data and audio data in the photography-prohibited area.

[Problems to be Solved by the Invention] However, the above-described conventional image/audio simultaneous transfer method can be realized when there is only one area that must not be photographed, but there are several areas that must not be photographed. There is a drawback in that it is not possible to prohibit the transfer of image data and audio data when the transfer of image data and audio data reaches multiple locations.

[Means for Solving the Problems] In order to solve these problems, the simultaneous image/audio transfer method according to the present invention is provided with a means for storing an area that the camera is not allowed to shoot, If it falls within a preset range, the transfer of image data and audio data is temporarily stopped, and if it falls outside of this range, it restarts the transfer of image data and audio data.

[Operation, use] If the shooting direction of the camera falls within a preset range, the transfer of image data and audio data will be temporarily stopped, and if it moves out of this range, the transfer of these data will be resumed. . As a result, even if there are several areas that should not be photographed, by setting these several areas in advance, it is possible to prohibit the transfer of image data and audio data within this range, and also make it possible to take pictures again. Once within this range, image data and audio data can be transferred.

[Example] Next, the present invention will be explained with reference to the drawings.

The figure is a block diagram showing an embodiment of the simultaneous image/audio transfer system according to the present invention. image/audio output device; 5 is an image/audio output device;
6 is a camera side control device, 7 is a data converter, and 8 is a storage device. The camera 1 to storage device 8 constitute a camera-side device. On the other hand, the terminal side device is configured as follows. That is, 9 is a display device for image reproduction, 10 is a speaker for audio reproduction, and 11
12 is an input device, 12 is a terminal side control device, and 13 is a data conversion device. Further, 14 is a communication network that connects the camera side device and the terminal side device.

Next, Table 1 is a table showing positional information of ranges that should not be photographed and is stored in advance in the storage device W8. 5
It is shown that two locations are stored: a range (2) from 0 degrees to 80 degrees and a range (2) from 120 degrees to 140 degrees.

Table 1 Next, the operation of the simultaneous image/audio transfer system according to the present invention will be explained.

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 positional information of the range that should not be photographed in advance. Assume that it is set at .

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

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

The control device 6 that has received this camera position information controls the camera drive mechanism 2 to obtain the current position, calculates the position information specified from the terminal device and the current position information, and stores this calculation result and the current position information. It compares the calculated value with the range stored in the device 8 that must not be photographed, and if the calculated value is not within the range stored in the storage device 8 that must not be photographed, the camera drive mechanism 2 is operated. In addition, if this calculated value is within the range that should not be taken, the image/audio switching device 5 is controlled to transfer the image and audio data from the image/audio output device 4 to the terminal side device. Switch to data.

Then, the control device 6 in the camera side device transfers the image and audio data to the image/audio output device 4 to be transferred to the terminal side device.
Even after switching to the data from the terminal device, camera position information is still received from the terminal device and calculations are performed between the camera's current position information and the camera position information received from the terminal device, but the result of this calculation is not stored. If the camera deviates from the range that is stored in the bag W8 where photography is prohibited, the image/audio switching device 5 is controlled to transfer the image and audio data back to the original camera 1.
Then, the data is returned to the image and audio data from the microphone 3 and transferred to the terminal device.

In the above explanation, we have described a method in which all calculations of camera position information are performed on the camera side, but three devices, the image/audio output device 41, the image/audio switching device 5, and the storage device 8, are installed on the camera side. Instead, it is installed in the terminal device, and the location information of the camera 1 is transferred to the terminal device via communication ¥1I414 every time the camera 1 moves, so that the range that should not be photographed is managed on the terminal device. It is obvious that functions completely equivalent to those described above can be realized.

Furthermore, in this embodiment, a case has been described in which there are multiple photography prohibited ranges only in the pan direction, but it is easy to set in the storage device 8 a photography prohibited range that combines the tilt direction and the zoom lens ratio. It is obvious that any combination of photography prohibited areas can be realized by the present invention.

Table 2 shows the state of the storage device 8 when a plurality of shooting prohibited ranges are set in the pan direction and the tilt direction. ≦Pan direction<360° ・・(1)=9
0°≦Tilt direction→−90” ((2)).

In Table 2, in the pan direction range 50 degrees to 80 degrees, the whole angle in the tilt direction, that is, from 190 degrees to +90 degrees,
In the range 120 degrees to 140 degrees in the pan direction, all angles in the tilt direction, i.e. 190 degrees to +90 degrees, and 20 degrees in the pan direction.
In the range 0 degrees to 210 degrees ■, all angles in the tilt direction,
In other words, the situation is shown when photography prohibited ranges are set at three locations from 190 degrees to 0 degrees.

As shown in Table 2, the same operation as described above is also performed when three photographic prohibited ranges (1) to (3) are set in the storage device 8. In other words, these photography prohibited areas
In (3), the transfer of image data from the camera 1 and audio data from the microphone 3 is prohibited, and instead, image and audio data from the image/audio output device 4 are transferred to the terminal side device, and Prohibited range■～
In cases other than (2), image data from the camera 1 and audio data from the microphone 3 are transferred to the terminal device.

As described above, an object of the present invention is to enable simultaneous image and audio transfer even when there are multiple areas where photography is prohibited, and for this purpose, it is possible to store multiple areas where photography is prohibited. A storage device 8 is provided, and when the camera 1 is in operation and the camera shooting direction enters the photography prohibited range stored in the storage device 8, the image and audio data from the camera side are not transferred, but are transferred to a predetermined direction. The image and audio data from the camera are switched to and transferred, and when the camera returns to the photographable range again, the image and audio data from the camera side are transferred.

As explained above, the present invention has the advantage that even if there are multiple areas where photography is prohibited, it is possible to simultaneously transfer images and audio beyond these photography prohibited areas, making it an extremely superior device for this type of device. It has a great effect.

[Effects of the Invention] As is clear from the above explanation, the simultaneous image and audio transfer method according to the present invention transfers image data and audio data when the shooting direction of the camera falls within a preset range. We have made it possible to temporarily stop the transfer and restart the transfer of these data if it falls outside of this range, so even if there are several areas that should not be photographed, you can set these several areas in advance. If this is done, the transfer of image data and audio data can be prohibited within this range, and when the camera returns to the photographable range, the image data and audio data can be transferred again.
