Abstract

A video-image control apparatus enables a client to obtain the details of an object in a displayed video image. For this purpose, when the angle of a camera 1003 is changed in accordance with an instruction from an external device, it is determined whether or not the object (e.g., a copier) is within an image sensing view. If it is determined that the object is within the image sensing view, the current status of the object is obtained by request. Then, an image of a character string indicative of the status information is generated, and combined with the video image. The combined image is transferred via a communication interface unit to the external device.

Claims

1. A video-image control apparatus having video-image input means, which transfers a video image from a predetermined camera device, inputted in accordance with a request from a remote client, to the client comprising:

storage means for pre-storing position data of an object and identification information identifying an apparatus which supplies information related to the object;

request means for requesting information relating an object to the apparatus by using identification information stored in said storage means if the object is in the video image inputted by said video-image means; and

transfer means for transferring the video-image and information related to the object obtained by said request means to the client, wherein the object is an information processing device or system which transfers status information upon issuance of status-information acquisition request via a predetermined communication means.

2. The video-image control apparatus according to claim 1, further comprising:

generating means for generating an additional image based on information related to the object in the video image inputted by said video-image input means; and

combining means for combining the additional image generated by said generating means, with the video image inputted by said video-image input means;

wherein said generating means has determination means for determining whether or not the video image inputted by said video-image input means includes the object, based on position data stored in said storage means,

and wherein if said determination means determines that the video image includes the object, said generating means generates the additional image.

3. The video-image control apparatus according to claim 1, wherein said generating means has:

determination means for determining whether or not the video image inputted by said video-image input means includes the object; and

status-information reception means for issuing a status-information acquisition request to the object if said determination means determines that the video image includes the object, and receiving status information from the object,

and wherein said generating means generates the additional image based on the status information received by said status-information reception means.

4. The apparatus according to claim 1, wherein said object is a device having a network interface.

5. A control method for a video-image control apparatus having video-image input means, which transfers a video image, inputted in accordance with a request from a remote client, to the client comprising:

a storage step for pre-storing position data of an object and identification information identifying an apparatus which supplies information related to the object;

a request step for requesting information relating an object to the apparatus by using identification information stored in said storage step if the object is in the video image inputted by said video-image means; and

a transfer step for transferring the video-image and information related to the object obtained by said request step to the client,

wherein the object corresponding to the pre-stored information is an information processing device or system which transfers status information upon issuance of status-information acquisition request via a predetermined communication means.

6. The control method according to claim 5, wherein said video-image input means inputs the video image from a predetermined camera device.

7. The control method according to claim 5, further comprising:

a generating step for generating an additional image based on information related to the object in the video image inputted by said video-image input means; and

combining step for combining the additional image generated by said generating step, with the video image inputted by said video-image input means;

wherein said generating step has a determination step of determining whether or not the video image inputted by said video-image input means includes the object, based on position data stored in said storage step,

and wherein if it is determined at said determination step that the video image includes the object, the additional image is generated at said generating step.

8. The control method according to claim 5, wherein said generating step has:

a determination step of determining whether or not the video image inputted by said video-image input means includes the object; and

a status-information reception step of issuing a status-information acquisition request to the object if it is determined at said determination step that the video image includes the object, and receiving status information from the object,

and wherein the additional image is generated at said generating step based on the status information received by said status-information reception means.

9. The apparatus according to claim 5, wherein said object is a device having a network interface.

10. A storage medium containing a program which functions as a video-image control apparatus having video-image input means, which transfers a video image, inputted in accordance with a request from a remote client, to the client comprising:

storage means for pre-storing position data of an object and identification information identifying an apparatus which supplies information related to the object;

request means for requesting information relating an object to the apparatus by using identification information stored in said storage means if the object is in the video image inputted by said video-image input means; and

a transfer means for transferring the video-image and information related to the object obtained by said request means to the client,

wherein the object corresponding, to the pre-stored information is an information processing device or system which transfers status information upon issuance of status-information acquisition request via a predetermined communication means.

11. The apparatus according to claim 10, wherein said object is a device having a network interface.
