Abstract: An image transmission apparatus includes a color codec section (108) for performing color image coding of a color image, a run-length codec section (109) for performing run-length coding of a monochrome image, and a switching unit (110) for arbitrarily switching the codec sections (108,109) and to perform coding in units of pages in one communication cycle depending on whether each page is a color image or a monochrome image. Whether each page is constituted by a color image or a monochrome image is set in advance, and corresponding information is stored in a memory (105). Coding is performed by a coding scheme set for each page, and the coded data is transmitted. Alternatively, coded data obtained by both the codec sections (108,109) are stored in a hard disk (107) and the data coded by a coding scheme, which an apparatus (300) at the other end of a communication line can handle, is read out and transmitted.

Abstract: PROBLEM TO BE SOLVED: To attain proper communication in a virtual space by a user belonging to the virtual spaces (groups). SOLUTION: Each user sets the specified virtual space in advance among a plurality of virtual space. A host server 11 receives user information transmitted from one of user terminal units 13-17, distributes received user information to the user terminal unit positioned in the specified virtual space which is set by the user of the user terminal unit being the transmission source of the user information and distributes the received user information to the user terminal units positioned in the virtual spaces except the specified space among the virtual spaces which are set by the user of the terminal unit being the transmission source of the user information. The user terminal unit to which the user information is distributed displays it.

Abstract: PROBLEM TO BE SOLVED: To facilitate recognition of the situation of a user. SOLUTION: The image of a user photographed by a video camera is fetched into a computer body (S1) and subjected to compression encoding (S2). When an office view display window is minimized or exists behind other application window, it is judged that the user is not viewing the office view (S3). The judged state of the user is transferred to host server equipment, together with the compressed image data via a network (S4). A user terminal receives the image of other users from server equipment 12 (S5), expands the image (S6), and displays the image on a display unit 44 (S7). In order to comprehend the situation of the user from the received using situation information of the user, the using situation of other user is displayed on the office view (S8). If the user does not designate ending, processes subsequent to the step S1 are repeated (S9).

Abstract: PROBLEM TO BE SOLVED: To provide a communication system which can set the access right information of a specific user who can refer to a reception document without needing any OCR, original protocol or the like. SOLUTION: A server terminal device 101 provides the first page of document information transmitted from outside to all the registered users registered in advance as users for client terminal devices 104a to 104f through a network 103 (a WWW browser). Also, the server terminal device 101 provides the document information from the second page onward to the specific user registered as a user who can refer to all the pates of the document information out of all the registered users by way of the network 103 so that the information can be referred to.
