Abstract

A camera control system having a terminal device connected to a plurality of cameras via a network is provided. In response to an operation that exceeds a maximum control value (maximum control angle) of the PTZ of a camera that is the target of control, the terminal device displays peripheral camera information, which corresponds to a shooting direction in which the operation has been requested, together with video shot by the camera being controlled. The peripheral camera information includes installation camera position information, viewable angle information, control status information and peripheral map information as well as at least one item of captured video from a camera other than the camera being controlled.

Claims

1. A camera control apparatus for selecting and controlling one of a plurality of cameras connected to a network, comprising:

a determination unit configured to determine whether or not a camera control corresponding to an operation request exceeds a viewable angle of a control-target camera; and

a display control unit configured to cause camera information corresponding to the operation request to be displayed on a display device in response to the operation request in a case where the camera control corresponding to the operation request exceeds the viewable angle of the control-target camera.

2. The apparatus according to claim 1, wherein said display control unit causes video from the control-target camera and the camera information to be displayed on the same screen.

3. The apparatus according to claim 1, wherein said display control unit causes position information, viewable angle information, control status information and map information concerning the control-target camera as well as at least one item of captured video from a camera other than the control-target camera to be displayed as the camera information.

4. The apparatus according to claim 1, wherein said display control unit accepts selection of a camera, which is to be controlled, from the camera information displayed.

7. The method according to claim 1, wherein said display control step causes position information, viewable angle information, control status information and map information concerning the control-target camera as well as at least one item of captured video from a camera other than the control-target camera to be displayed as the camera information.

5. A method of controlling a camera control apparatus for selecting and controlling one of a plurality of cameras connected to a network, comprising:

a determination step of determining whether or not a camera control corresponding to an operation request exceeds a viewable angle of a control-target camera; and

a display control step of causing camera information corresponding to the operation request to be displayed on a display device in response to the operation request in a case where the camera control corresponding to the operation request exceeds the viewable angle of the control-target camera.

6. The method according to claim 5, wherein said display control unit causes video from the control-target camera and the camera information to be displayed on the same screen.

8. The method according to claim 5, wherein said display control step accepts selection of a camera, which is to be controlled, from the camera information displayed.

9. A storage medium storing a computer-readable program for causing a computer to perform as a camera control apparatus for selecting and controlling one of a plurality of cameras connected to a network, said program comprising:

a code for determining whether or not a camera control corresponding to an operation request exceeds a viewable angle of a control-target camera; and

a code for performing a display control step of causing camera information corresponding to the operation request to be displayed on a display device in response to the operation request in a case where the camera control corresponding to the operation request exceeds the viewable angle of the control-target camera.
