Arrangement and method for performing video conferences

The invention relates to an arrangement for performing video conferencing in accordance with the preamble of claim 1 and a method for performing video conferencing in accordance with the preamble of claim 14.

Teleconferencing systems in which both voice and image data are transferred, are well known. In these systems, a telecommunications realisierendes device is equipped with a video camera and placed in such a way as to connect one or more speakers on a subscriber side with speakers on a remote subscriber side.

The disadvantage here is that a camera is provided for this purpose in most cases fixed and only be moved manually.

The object underlying the invention is to provide an arrangement and a method which allows a more flexible implementation of video conferencing.

This object is based on the features of the preamble of claim 1 by arrangement whose characteristic features as well as on the basis of the features of the preamble of claim 14 accomplished by the characterizing features thereof.

In the inventive arrangement for performing video conferences where each participant side, a first camera with a central device is connected for operating a telecommunication connection is assigned to at least to at least one of the participants sides a second camera to a subscriber of the subscriber side. The second camera is connected to the central device and configured such that a encompassed by their first photographically ER- area follows the head movements of the user. In addition, the first camera and the second camera is configured such that each of a second photographic image captured by the first camera area is transmitted to the first time points over the telecommunication connection as a video image by the second camera is directed to the first camera.

The inventive arrangement, a system is provided which makes it possible to control the transmission of the first camera, without having to manually act on them. Here, the first camera and the second camera is preferably designed such that in disjoint to the first time points second times, the first photographically erfass- th field is transmitted as a video image. Thereby ER is sufficient that far more than just the people involved at the Conference Televideokonfe- is transmitted as image information, for which purpose the support of the second camera has to turn his head in the direction of the object to be transferred only. As a rule, therefore, is all that is in the field of view of the user or wearer of the second camera, transferred, except for the first times where the user looks inside directly into the first camera. So this way you are to convey its conference partners are able, documents and other non that are available in view of the first camera objects.

Preferably, the compound of the first camera and / or second camera to the central facility via a wireless connection is realized. This allows, for example, the free movement of the carrier of the second camera in space, but also the position of the first camera can be flexibly selected without limitation by cable length, or the like freely.

Furthermore, it is preferable that the first camera and / or the second camera are designed such that the cordless connection according to the Bluetooth or the IEEE standard of 802.11 standard or derivatives thereof working. This guarantees that a quick installation of the first and / or second camera into existing popular networks that allow this radio communication possible.

Alternatively, or in addition, the connection of the first camera and / or second camera to the central facility via a schnü bound compound. This is especially advantageously employed, for example, when importance is attached to low exposure to electromagnetic waves or have a too high load on the energy resources of the first and / or second camera to the sequence by the radio transmitting / radio receiving devices.

Preferably, the second camera is configured as part of a headset so that correlates the first photographically recorded region with the direction of view of the subscriber With the headset. This results in a simple construction of the arrangement according to the invention is ensured, which also allows for rapid deployment and function according to the invention. Is the central institution as configured for telecommunications data processing device, designed especially personal computers, the properties of data processing devices to implement the telecommunications can advantageously be used. In particular, the computing capacity that provides a data processing device available, is particularly advantageous.

Alternatively, the centralized facility may also be formed as ausgestaltetes for video transmission landline telephone. This embodiment is advantageously usable when special importance is attached to telephony functions.

In a further alternative embodiment, the central device may be configured for video transmission as cordless telecommunications device, in particular a formed according to the DECT standard functioning base or mobile station. thereby further increasing the flexibility is achieved in particular in the embodiment as mobile station.

Preferably, the first camera or the second camera is configured with a transmitting device which emits electromagnetic radiation directed. This further makes it possible, first and second points in time just tektieren to de- namely in that the first or the second camera detects the light emitted from the respective other camera e- lektromagnetisehen waves through the camera lens, to which end generally electromagnetic waves be selected in the visible region. This embodiment can even further form in which the first camera or the second camera is configured with a separate receiving means, detects the specifically directed for this purpose electromagnetic radiation. In this way, for example, also possible to choose the electromagnetic radiation from the non-visible range to use for example infrared emitter, which can be detected by the other side with a corresponding infrared detector, so that when the first camera is directed exactly to the second camera, even the image of the first camera shall be transferred. The use of infrared light would also have the

That have non-visible advantage because of your property, waves that captured by the cameras image does not distort. Alternatively, or additionally, the first or the second camera having a device for overall directed reflection of incoming electromagnetic radiation to be configured. In addition, also avoids that a respective user may be blinded by the rays. This is for example a relatively inexpensive design option as an emitter, only needed during the other party has a reflection device that does not need its own power supply, as a rule, so that an energy saving effect. In the inventive method for performing video conferences, particularly in an arrangement of the aforementioned type, in which each participant side, a first camera with a central device is connected for operating a telecommunication connection is on at least one of the participants sides of at least a second camera to a subscriber of the subscriber side assigned, determines a photographic image captured by the second camera first region Gl by the direction of view of the participant as well as a photographic image captured by the first camera second area G2 while transmitted as the current video image as the second camera is directed to the first camera.

By this method, an easy-to-implement approach is essentially independent of the specific arrangement given that achieves the advantages mentioned above, this being achieved the optimum effect when used in the inventive arrangement.

Further details and advantages of the invention will be explained with reference to the illustrated in the single FIGURE embodiment of the invention.

The figure shows schematically the sequence and arrangement of the method of the invention.

In the figure two timing points are shown, which are detected in accordance with the invention and each lead to the result that, for a participating in the video conference page to another camera image is recorded.

On the right side, a first time Tl is initially displayed, in which the head of a user USER lekommunikationseinrichtung a Te, the insurance according to the example shown a execution designed as a personal computer terminal PC is is directed. Furthermore, it can be seen that the telecommunications device PC is connected to a mounted first camera LSI. It is also clear that a second camera LS2 is at the head of the user USER, which usually through a headset is fixed to the head that the camera is always directed in the direction of view of the user USER DER art on, so that a first photographically captured area Gl LS2 of the second camera corresponds to the field of view of the user uSER.

In the representation is further seen that for the first time Tl, the viewing direction of the user USER is aligned in the direction of the telecommunications device PC, so that the first photographically recorded area Gl detects the first camera LSI. Is now the first camera LSI equipped with an infrared transmitter and the second camera LS2 with an infrared receiver is detected at this time, the infrared signal from the second camera LS2 and for example, transmits this to the PC, so that this transmitted as the current image that of video signal via a telecommunica mu nikationsverbindung is transferred, which receives the first camera LSI. This is the time Tl, as shown, the head of the user.

At the second timing T2 of the head of the user USER is directed to an object, such as a graphic OB, which is in paper form, so that the second connected with its head camera LS2 is rotated in this direction and whose first photographically captured area Eq the object OB captured as an image.

This movement of the head has the result that the first photographically recorded area Eq not the first camera LSI includes, so that a light emitted from the first camera LSI infrared signal from the second camera LS2 not detected and the lack of detection of even the subscriber telecommunications device PC is reported. The telecommunication device PC switches to such a second times, the first of the second camera LS2 photographically recorded area Gl as a video image on the telecommunication connection through, so that the transferred image will correspond to the image, which detects the second camera LS2, in this case, the graphic OB ,

Transmitting the detection of the infrared light and transmitting the video data may be carried out according to the invention via a cordless radio communication, which can for example be designed according to the Bluetooth or IEEE 802.11. Are also possible alternatives for the infrared rays, for example, it would be conceivable that the telecommunications device PC simply evaluates the image of the first camera LSI and only detects whether in this image the lens of the second camera LS2 is directed to the first camera LSI.

eg This variant saves the cost of an infrared transmitting / receiving device. In addition, no more onerous radiations are emitted.
