摘要： A plurality of handheld or "mobile" information terminals (10a - 10n) send forth position information detected periodically toward an information delivery server (50); the information delivery server (50) comprises a position management unit (50-4) for generating image data used to compose for visual display certain users belonging to the same group onto the same land map image screen, a situation/history management unit (50-7) for arithmetically processing the user's distribution in units of target facilities and then generating information indicative of such distribution, an image management unit (50-9) for storing therein more than one photographic image as sent from mobile information terminal(s) in units of users or alternatively in units of groups and then transferring the stored image toward a target or "destination" mobile information terminal, and a route search management unit (50-6) for searching for a recommendable route in view of the degree of congestion and/or popularity as calculated at the situation/history management unit (50-7). In a multimedia information delivery system, perform provision of information services by recognizing the position of a user and then utilizing the user position thus recognized.

摘要： An image display apparatus having a computer system (100) and an image processor (500). The computer system (100) includes: a personal computer having a CPU (210) and a main memory (220); and input/output apparatuses such as magneto-optical disk drive (300), image scanner (330), color printer (340), etc. The image processor (500) which commonly uses a system bus (150) of the computer system (100) includes an independent dedicated image bus (550), a compression/expansion unit (510), an image memory read/write controller (520), image memories (610, 620, 630), and a video processor (650). Image data which is sent from the magneto-optical disk drive (300) is decoded by the compression/expansion unit (510) and is held in the image memories. The image data of the image memories is transferred to the video processor (650) through a dedicated signal line and is displayed on a large screen projection display (700).

摘要： The invention relates to a method and a device for controlling vertical scan speed when a document (10) and a recording medium are moved in a vertical scanning direction to read the document (10) and record signals on the recording medium, the read signals are stored in a line buffer memory (50) and code signals corresponding to the read signals in a code buffer memory (70). The present invention changes over a high speed vertical scan mode with hysteresis to a low speed vertical scan mode and vice versa in accordance with the number of buffered code bits in the code buffer memory (70) to read the document and record the signals on the recording medium. Thus, the present invention reduces the number of stops of vertical scan.
