When a camera server receives an instruction involving invalidation of viewing limitation (masking processing) of video from a privileged client, the camera server limits viewing of video data with respect to a general client and a recording client. The camera server stores the video data of a limited period in a secondary storage device. When the camera server receives an instruction involving validation of the viewing limitation from the privileged client, the camera server transmits the stored video data of the limiting period to the recording client.

Server apparatus and method of transmitting video data

An image processing apparatus includes a setting unit configured to set, in a first range encompassing an area of a captured image acquired by an imaging unit, a first analysis graphic or a first line on a display screen displaying the first analysis range, and set, in the first setting range, a display range of the captured image to be displayed on a display unit, and a determination unit configured, when the display range is such that the first graphic or the first line set in the first range is partially located outside the display range, to determine a second analysis graphic having a number of vertexes equal to or smaller than a number of vertexes of the first analysis graphic, and contained within the display range or a second line contained within the display range.

Image processing apparatus, control method, and recording medium

An image processing apparatus includes an acquisition unit configured to acquire a video, a superimposition unit configured to superimpose an image onto the video acquired by the acquisition unit, and a detection unit configured to detect the emergence of an object in a video in a detection area set on the video acquired by the acquisition unit, wherein the superimposition unit superimposes an image corresponding to the size of the object to be detected when emerging by the detection unit onto the video in the detection area, and outputs the resultant video to the detection unit.

Image processing apparatus, method, and storage medium for analyzing changes in video

An analysis apparatus analyzes an image and performs counting of the number of object passages. The analysis apparatus executes the counting and outputs the execution status of the counting.

Analysis apparatus, analysis method, and storage medium

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

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.

System for operating device from remote location and apparatus for use in the system

For easy operation of switching a plurality of cameras, the cameras are arranged in juxtaposition such that the image-sensible range between the cameras partially overlap each other. A frame indicative of a combined image-sensible range which includes an image-sensible range of each of the plurality of cameras is displayed on a monitor screen, and a frame indicative of an image-sensing range of a selected camera is displayed in the frame with a position and size corresponding to the direction and magnification of the image sensing. A sensed image of a corresponding camera is continuously displayed in the frame . By moving the frame , the image-sensing direction of the corresponding camera is controlled, and by enlarging/reducing the frame , the magnification of the corresponding camera is controlled. When the frame is moved to an image-sensible range of another camera, a camera subject to the control operation or image displaying is switched to another camera which corresponds to the new image-sensible range.

Camera control apparatus and method

In order to carry out display control of an operating panel and realize an orderly display of an image picked up by a camera which is being controlled, an empty area in which an image picked up by one or more cameras is not displayed is searched for on a display screen, and a new picked-up image obtained from the one or more cameras is displayed in the empty area found.

Camera control system

In a display of a hyper text, a hysteresis of an access to a reference file is stored into an access hysteresis file together with attribute information of the reference file. On the basis of the hysteresis of the access stored in the access hysteresis file, the presence or absence of the access to the file on the reference destination side corresponding to each link is judged. With respect to the reference file which was judged such that there was the access, on the basis of the attribute information stored in the access hysteresis file, a variation after the access of the reference file is detected. A link corresponding to the reference file is displayed in a display form according to the detected variation in a manner such that the presence or absence of the access which was judged can be discriminated. Thus, in a hyper text system, the user can recognize the variation after the access of the reference file which was accessed before.

Hyper text system and its display method

A cooperative activity system, in which a plurality of computer devices are connected via a network, performs an activity by cooperation among the computer devices. A server for recording data is connected to the network and monitors data transferred to the network, creates a keyword conforming to the type of data when the data is transferred and stores the keyword in a file. While data is not being generated, a keyword is created depending upon (1) whether a specific time has arrived, (2) the lapse of time spent in a certain length of a cooperative activity or (3) the passage of a prescribed period of time from an immediately preceding item of data, and both the keyword and the particular event are stored as a file. As a result, desired cooperative activity data can be read out by performing retrieval based upon the keyword.
