An end user is provided with an environment to easily remote-control a video camera via a general network such as the Internet. For this purpose, on a client side, the content of camera control is described in file-transfer protocol description, and the description is transferred to a camera server on the Internet via a browser. The camera server interprets the description, controls a camera in accordance with the designated content, to perform image sensing, and returns the obtained video image as the content of a file to the client. The client performs various controls while observing the video image. When a desired angle has been found, the client instructs to register the angle in a bookmark, then angle information displayed at that time is registered. Thereafter, when the user of the client can see the video image obtained on the same image-sensing conditions by merely select-designating the angle information registered in the bookmark.

A document processing apparatus which permits the sharing of a document element in a document structure while ensuring that any change to the content appears in the document element in each document sharing it. In a document processing apparatus for managing a plurality of documents each containing a plurality of document elements, a document element having content to be shared with a second document is designated from a plurality of document elements of a first document, and the content of the designated document element is defined as the content of a predetermined document element of the second document to be shared as common content by the first and second documents. Further, any document element having shared content is detected from a document when the display of the document is commanded, and is displayed in a distinguishable manner from other portions.

Document processing to permit sharing of content by plural documents

A camera control apparatus provides an end user with environment to easily remote-control a video camera via a general network such as the Internet. When the camera control apparatusreceives a file-transfer request described in the format of the network from an external deviceconnected to the apparatus, it handles a characters in a character string of a file name of the request as camera-control characters. As a result, if the character string includes description corresponding to the format for camera control, the camera control apparatuscontrols the camera in accordance with the description to perform image sensing, and transfers the obtained video image as the content of an image file requested by the external device as the file-transfer request originator.

Apparatus and method for controlling a camera connected to a network

This invention allows easy update of an image to be included in a document which is submitted on the network. For this purpose, data that set the image sensing times and image sensing states of a camera () the pan angle, tilt angle, and zoom ratio of which can be varied, are stored in an HD (). If one of the stored times has been reached, image sensing is done in accordance with the set contents, and the obtained image is stored in the HD (). Upon launching a candidate edit program, an old document inserted with images is displayed on a CRT (). When a desired image is designated, it is substituted by a new, sensed image candidate corresponding to that designation position. The created document is then uploaded to a WWW server.

Information processing apparatus, its control method, and storage medium

A camera control apparatus provides an end user with environment to easily remote-control a video camera via a general network such as the Internet. When the camera control apparatus receives a file-transfer request described in the format of the network from an external device connected to the apparatus, it handles the characters in a character string of a file name of the request as a camera-control characters. As a result, if the character string includes a description corresponding to the format for camera control, the camera control apparatus controls the camera in accordance with the description to perform image sensing, and transfers the obtained video image as the content of an image file requested by the external device as the file-transfer request originator.

Disclosed is a remote operating system in which even if a remote-operated apparatus is connected to a network protected by a firewall and a remote-operating apparatus exists outside of the firewall, it is possible for the remote-operating apparatus to remotely operate the remote-operated apparatus by transmitting information containing an operation designation as a response to a command, such as a stream connection request, transmitted from the remote-operated apparatus.

When the camera control apparatus receives a file-transfer request described in the format of the network from an external device connected to the apparatus, it handles a characters in a character string of a file name of the request as camera-control characters. As a result, if the character string includes description corresponding to the format for camera control, the camera control apparatus controls the camera in accordance with the description to perform image sensing, and transfers the obtained video image as the content of an image file requested by the external device as the file-transfer request originator.

A server which smoothly transmits/receives a moving image from image sensing device via the Internet. The server comprises a camera which converts an object image into an image signal, a camera controller which controls the camera, and a camera driver. When the image signal converted by the camera is transferred as still-image data on the Internet, the data is transferred by the HTML or HTTP protocol, on the other hand, when the image signal is transferred as moving-image data, the data is transferred by another protocol.

Server, terminal and control methods for transmitting real-time images over the internet

An image-sensing server performs moving-image transfer service by sequentially transferring live video images obtained by a video camera via a general network such as the Internet. When live video images are requested from an external device as a client on the network, a system controller controls data-transfer amount per unit time of an image obtained by image sensing by the video camera, in accordance with traffic status on the network, and transfers the image data to the external device.

Image-sensing server and control method and storage medium therefor

A comment added to a certain portion in a first document can be automatically re-added to an equivalent position in a second document, and comment transfer processing between documents is automatically performed. Position information of a comment with respect to an old document obtained from an old document comment file is stored in a position information area, and comment contents also obtained from the old document comment file are stored in a comment content area. A character string corresponding to the position information is extracted from an old document file, and is stored in a character string area. A new document file is searched on the basis of the character string stored in the character string area, and position information of the detected character string is stored in a candidate area. One of position information stored in the candidate area is selected according to a predetermined rule, and the selected position information is stored in a new position information area. The comment contents stored in the comment content area, and the position information stored in the new position information area are written in a new document comment file.

Document processing method and apparatus which can add comment data added to an original document to a revised document

An image editing apparatus has a display screen such as a CRT screen on which are displayed or stacked a plurality of partial image elements so as to form an image of a desired illustration with a sense of depth.
