Abstract

An image sensing system, including visual telephone and teleconference terminals, connected via a network. Each terminal has a video camera placed on a pan head, and can display a video image sensed by the video camera connected to the terminal and a video image sensed by a video camera of a communication-destination terminal, on a monitor connected to the terminal. Each terminal detects whether or not the video camera is placed on the remote-controllable pan head, and mutually transmits the result of detection to its communication-destination terminal. At each terminal, if the direction of the video camera can be controlled by the pan head, a pan-head control panel is displayed with the video image from the video camera, on the monitor. Further, if the video camera of the communication-destination terminal is placed on a remote-controllable pan head, a pan-head control panel for the pan head of the communication-destination terminal is displayed with the video image from the communication-destination terminal, on the monitor.

Claims

image sensing means;

a pan head for controlling an image sensing direction of said image sensing means;

detection means for detecting whether or not said pan head and said image sensing means are connected to each other; and

display control means for controlling a displaying status of a control panel for designating the image sensing direction by the pan head based on a detection detected by said detection means.

2. The image sensing control apparatus according to claim 1, wherein said detection means detects whether or not said pan head and said image sensing means are physically connected.

3. The image-sensing control apparatus according to claim 1, wherein said detection means detects whether or not said pan head and said image sensing means are electrically connected.

4. The image-sensing control apparatus according to claim 3, wherein said detection means detects status of electricity-supply to said pan head.

5. The image-sensing control apparatus according to claim 1, wherein if said detection means detects that said pan head and said image sensing means are not connected to each other, said display control means does not display the control panel.

6. The image-sensing control apparatus according to claim 1, wherein said display control means displays the control panel, if said detection means detects that said pan head and said image sensing means are connected to each other.

7. The image-sensing control apparatus according to claim 1, wherein said said image sensing means is placed on the pan head.

8. An image-sensing control method for an image sensing control apparatus for controlling image sensing means and a pan head for controlling an image sensing direction of said image sensing means, comprising:

a detection step of detecting whether or not said pan head and said image sensing means are connected to each other; and

a display control step of controlling a displaying status of a control panel for designating the image sensing direction by the pan head based on a detection detected at said detection step.

9. The image-sensing control method according to claim 8, wherein at said detection step, whether or not said pan he ad and said image sensing means are physically connected is detected.

10. The image-sensing control method according to claim 8, wherein at said detection step, whether or not said pan head and said image sensing means are electrically connected is detected.
