It was difficult to examine in which location of which device installation map an icon of a desired network device has been arranged. A link to the device installation map is displayed in correspondence to the network device and the icon indicative of the designated network device is emphasis-displayed.

Network management system, display method, and program

A network managing method provides a device list with which device information with regard to a plurality of devices is arranged in order and displayed for every device. A type of at least one device information to be displayed in the device list is designated from among a plurality of types of predetermined device information capable of being displayed in the device list. A type of the device information to be used as display criteria is also designated in the case where a plurality of devices are arranged in order in the device list. The device information of the type designated as the display criteria is controlled to be displayed in the device list even if the designated display criteria is not included in the type of information designated for display in the list.

Network management method for providing device list and network management device to provide device list

In a management system for managing network devices connected to a network, it is considered to reduce the load of the network and the devices by preserving device information acquired from each device and not acquiring new information from the device for a predetermined period. However, this approach has a problem in that the user cannot know when the displayed information was acquired. In the present invention, when preserving device information, the time of acquisition of the device information is preserved as acquisition-time data, which is displayed within displayed information together with the device information. The above-described probem is thereby solved, and the user can acquire very reliable information.

Network-device management apparatus and method, recording medium, and transmission apparatus

An image communication system can transmit and receive an image via a communication line. The system supplies a self-portrait image from a self-portrait photographing unit and a partner image from a partner photographing unit and displays the self-portrait image on a self-portrait display window and the partner image on a partner display window on the same screen. The system discriminates whether a designated point exists in the self-portrait display window or the partner display window. If the designated point exists in the self-portrait window, self-portrait photographing unit control information is calculated by a self-portrait calculating method and if the designated point exists in the partner display window, partner photographing unit control information is calculated by a partner calculating method. If the designated point exists in the self-portrait window, the self-portrait photographing unit is controlled so as to move a part of an image at the designated point to a center of the self-portrait display window, whereas if the designated point exists in the partner display window, the partner photographing unit is controlled so as to move a part of an image at the designated point to a center of the partner display window.

Image communication system and method utilizing self-portrait and partner display windows

An image communication apparatus generates a command, which controls a communication partner to cause a part of the communication partner to move mechanically, to be transmitted through a communication line. The apparatus further prevents the communication partner from operating incorrectly according to the command which is transmitted after a predetermined delay time of the communication line.

A multi-point-to-point conferencing system comprising a plurality of terminals connected by a network including data and control channels is disclosed. In a particular embodiment, the network is an Integrated Services Digital Network (ISDN) having data (B) channels and a control (D) channel. The conference is established in a manner that does not waste connection setup attempts or data channel connect time by attempting to establish a conference when a participating terminal does not have the necessary data channels available. The terminal initiating the conference communicates with at least one participating terminal to determine the use status, or availability, of the required number of data channels. If a participating terminal decides to join the conference, either automatically or through user confirmation, the participating terminal (1) reserves the required data channels for a limited time such that connection requests are only accepted from conference terminals and (2) communicates its decision to the initiating terminal. Now knowing that data channel connections can be successfully established between those terminals ready to participate, the initiating terminal initiates a conference using normal multi-point-to-point connection procedures.

An image input system includes: an image pickup device movable at least from side to side; an image pickup direction designating device for designating the direction of movement at least from side to side of the image pickup device; a display form switching device for switching a display form for an image picked up by the image pickup device between two display forms: a real image display form in which the image is displayed as it is and a mirror image display form in which the image is displayed reversed left to right; and a control direction changing device which, when the display form is switched by the display form switching device, changes the correspondence of the designation regarding the direction of movement from side to side, given by the image pickup direction designating device, and the direction of movement from side to side effected in response to the designation.

In a communication system having a plurality of communication terminals connected by a communication circuit in the form of a loop or a bus, data circulated through the communication circuit has a multi-frame structure having a multiplicity of frames in which data fields are assigned to the terminals, and the circulated data is relayed and updated. If all data generated by the terminals is circulated through the communication circuit, each terminal may receive data generated from itself, which is essentially meaningless for the terminal. Data which has become essentially meaningless is deleted during communication to prevent such meaningless data from always occupying a part of the communication circuit to reduce the communication speed and the efficiency of utilization of the communication circuit.
