Abstract

A camera control system is disclosed where the control system selects a camera from a plurality of cameras connected to a network, and displays an image taken by the selected camera and further performs control functions on the selected camera. The control system first contains a map display, which represents the relative area where the plurality of controllable cameras are set. The control system next contains a symbol display configuration for representing each camera, and also contains a display-not-permitted area setting configuration, which disallows display functions relative to each network client'"'"'s status on the network. The control system subsequently transmits each client'"'"'s respective view and information in accordance to their request and corresponding status.

Claims

1. A camera control system for selecting a camera from a plurality of controllable cameras connected to a network, displaying an image taken by the selected camera and performing control of the selected camera, comprising:

map display means for displaying a map representing the relative area where the plurality of controllable cameras are set;

symbol display means for displaying at least one camera symbol representing a camera on the map displayed by said map display means;

display-not-permitted area setting means for setting a display-not-permitted area where taking video is prohibited on the map displayed by said map display means for each of clients on the network; and

transmitting means for transmitting an image taken by the selected camera as well as information regarding each of the clients, so as to restrict the display of images for each of the clients according to the display-not-permitted areas set for each of the clients.

2. The camera control system according to claim 1, wherein, each of the clients comprising camera-image-display regulate means for substantially prohibiting displaying of an overlapped portion of the video image, with respect to a camera subjected to restriction, when a range of the set display-not-permitted area and a video range of the subject camera overlap.

3. The camera control system according to claim 2, wherein, with respect to a camera subjected to restriction, when a range of the set display-not-permitted area and a video range of the subject camera overlap, the overlapped portion of the video image is displayed in significantly-lower resolution compared to other portions of the image.

4. The camera control system according to claim 2, wherein, with respect to a camera subjected to restriction, when a range of the set display-not-permitted area and a video range of the subject camera overlap, the overlapped portion of the video image is partially displayed.

5. A camera control system for selecting a camera from a plurality of controllable cameras connected to a network, displaying an image taken by the selected camera and performing control of the selected camera, comprising:

display-not-permitted area setting means for setting a display-not-permitted area for each of clients on the network; and

transmitting means for transmitting the image taken by the selected camera, as well as information regarding each of the clients, so as to restrict the display of images for each of the clients according to the display-not-permitted areas set for each of the clients.

6. The system according to claim 5, wherein said display-not-permitted area setting means selects a plurality of cameras to which the display-not-permitted area is set prior to set the display-not-permitted area on the map displayed by said map display means.

7. A method for selecting a camera from a plurality of controllable cameras connected to a network and displaying an image taken by, and performing control of, the selected camera comprising the steps of:

setting a display-not-permitted area for each of a plurality of clients on the network;

transmitting the image from the selected camera, as well as information regarding each of the clients and their respective display-not-permitted area, to each of the clients in order to restrict the viewing display of each of the clients according to their status on the network.

8. A computer readable program, stored in a storage medium for selecting a camera from a plurality of controllable cameras connected to a network and displaying an image taken by, and performing control of, the selected camera, said program comprising:

an input step of inputting data from a transmission source via a network;

a storing step of storing the data into a memory device;

an output step of outputting, by an output device, the data stored in the memory device, on the basis of a predetermined operation;

a display-not-permitted step for setting a display-not-permitted area for a plurality of clients on a network; and

a transmitting step for transmitting an image from the selected camera, as well as information for each of the clients set in the display-not-permitted area, to each of the clients in order to restrict the viewing display of each of the clients according to their status on the network.
