Abstract

The present invention relates to a transmitting communication device comprising:—a camera for capturing an image sequence with a display range; —a sensor for capturing environmental events that are not perceptible within the display range, —a processor for computing a control signal from the environmental events, and—a transmitting unit for transmitting the captured image sequence and the control signal to a receiving communication device.

Claims

1. A transmitting communication device comprising:

a camera for capturing an image sequence with a display range;

a sensor for capturing environmental events that are not perceptible within the display range,

a processor for computing a control signal from the environmental events, and

a transmitting unit for transmitting the captured image sequence and the control signal to a receiving communication device.

2. A transmitting communication device as claimed in claim 1, wherein the sensor is a wide-angle camera and wherein the control signal is computed from an image sequence captured by the wide-angle camera outside the display the range.

3. A transmitting communication device as claimed in claim 2, wherein the processor comprises means for detecting the face or faces of people within a viewing range of the camera, and means for zooming around this face or these faces so as to obtain the image sequence with the display range to be transmitted to the receiving communication device.

4. A transmitting communication device as claimed in claim 2, wherein the processor comprises means for estimating motion of an object entering into the viewing range of the wide-angle camera so as to derive a motion vector magnitude, which motion vector magnitude is included in the control signal.

5. A transmitting communication device as claimed in claim 4, wherein the processor comprises means for computing color information of pixels within the viewing range and outside the display range, said color information being included in the control signal.

6. A transmitting communication device as claimed in claim 1, wherein the sensor is a microphone array arranged to detect sound outside the display range, and wherein the control signal is computed from the microphone signals.

7. A transmitting communication device as claimed in claim 6, wherein the processor comprises means for performing acoustic source localization so as to detect a direction of a sound event, the direction of the sound event being included in the control signal.

8. A transmitting communication device as claimed in claim 1, wherein the processor comprises means for reducing the spatial or temporal resolution of the captured image sequence.

9. A receiving communication device comprising:

a receiving unit for receiving separately, from a transmitting communication device through a communication network, video data corresponding to an image sequence to be displayed with a display range and a control signal representative of environmental events not perceptible within the display range;

a display for displaying the video data;

light sources next to the display; and

a controller for interpreting the control signal so as to derive the environmental events and for controlling the light sources in dependence on the control signal.

10. A receiving communication device as claimed in claim 9, wherein the controller is adapted to derive motion information representative of the motion of an object outside the display range at the transmitting communication device side and a position of the object relative to the display so as to switch on the corresponding light source.

11. A receiving communication device as claimed in claim 9, wherein the controller is adapted to derive a motion vector magnitude representative of the amount of motion of an object outside the display range at the transmitting communication device side, an intensity of the light source being controlled in proportion of the motion vector magnitude.

12. A receiving communication device as claimed in claim 9, wherein the controller is adapted to derive color information representative of a position and/or motion of an object outside the display range at the transmitting communication device side, a color of the light source being controlled in dependence on the color information.

13. A receiving communication device as claimed in claim 9, wherein the controller is adapted to derive a magnitude of a sound emitted outside the display range at the transmitting communication device side, an intensity of the light source being controlled in proportion of the sound magnitude.

14. A receiving communication device as claimed in claim 9, wherein the controller is adapted to derive a direction of a sound emitted outside the display range at the transmitting communication device side so as to switch on the light source corresponding to the direction where the sound comes from.
