Abstract: An image-data receiving unit receives image data from other image communication apparatus. A storing unit stores therein the image data. An output unit outputs the image data stored in the storing unit. A reading unit reads the image data output by the output unit. An extracting unit extracts a difference between the image data read by the reading unit and the image data stored in the storing unit. A determining unit determines whether the difference extracted by the extracting unit satisfies a predetermined condition. A control unit controls a transmission of a message to other image communication apparatus based on a result of determination by the determining unit.

Abstract: Slave terminals and a master terminal are wirelessly connected according to the Bluetooth protocol. When a number of the slave terminals exceeds a predetermined number of the slave terminals for the wireless connection, the wireless connections are controlled by a predetermined set of rules. Active slave terminals are switched into inactive slave terminals according to the predetermined rules so as to efficiently use the resources in the system. The system is used for a data conferencing or class room instructions.

Abstract: An information-inputting device is provided, which includes a plurality of photographing units photographing an area on a plane. An object located on the plane is then extracted from an image that includes the plane and the object, and it is determined whether the object is a specific object. If the object is the specific object, a position of a contact point between the specific object and the plane is calculated.

Abstract: A method, computer readable medium, and apparatus for inputting information, including coordinate data, includes: extracting a predetermined object from an image, including a predetermined object above a plane; detecting motion of the predetermined object while the predetermined object is within a predetermined distance from the plane; and then determining if to input predetermined information.

Abstract: An optimal pen color is automatically selected for a given background color based upon a predetermined relative distance in the Munsell color-order system. The predetermined distance is defined in terms of saturation, hue and or lightness. In general, sufficient visual distinction is observed when the color representations of the pen and the background are separated by the predetermined relative distance in the Munsell color-order system.

Abstract: An electronic blackboard displays information and optically detects input information on a display/writing surface by determining the corresponding coordinates. To determine the input coordinates, a predetermined number of pairs of light emitting elements and light detecting elements are placed in parallel for each axis near the edges. The light emitting elements and the light detecting elements are also linearly and equidistantly placed. A control unit is connected to the light emitting elements for sequentially activating these light emitting elements and for controlling the light detecting elements to detect the light in an overlapping manner. Based upon the above positional information from the light detecting elements, an input coordinate determination unit determines the input coordinates of an input on the display/writing surface.

Abstract: A disclosed network communication apparatus for performing communication via an IP network includes: a packet generation unit generating packets for call connection including facsimile communication capability and voice capability; and a communication control unit requesting a target network communication apparatus for connection using the packets for call connection upon facsimile transmission and establishing a facsimile communication channel and a voice channel to perform the facsimile transmission. Upon facsimile transmission, the communication control unit requests the target apparatus for connection using the packets for call connection.

Abstract: In a communication system that includes a communication terminal that originates and receives a call through a call control server, the call control server receives destination information from the communication terminal as a call request. The call control server checks an address of the communication terminal and determines based on the destination information whether transmission to a destination terminal is permitted for the communication terminal. Only when the transmission is permitted, the call control server originates a call to an address corresponding to the destination information to connect the communication terminal to the destination terminal.
