Abstract: A navigation device calculates the distance difference between the position of a vehicle which is map-matched onto a road link, and the position acquired by perpendicular-mapping the actual position of the vehicle at a branch point onto the above-mentioned road link from the lane width K of a road lane along which the vehicle had been traveling before making a turn at the branch point, the lane width N of a road lane along which the vehicle has been traveling after making the turn, and the lane number B of the road lane before the branch point, the lane number A of the road lane after branch point, and the turning angle ? of the vehicle at the branch point, so as to correct the vehicle position in such a way that the vehicle position is the above-mentioned perpendicular-mapped position.

Abstract: A music device includes a characteristic extraction means 103 for extracting two or more characteristics included in music information from this music information, image generating means 105 to 111 each for generating an image which has variations which differ dependently upon each of the two or more characteristics extracted by the characteristic extraction means, and a monitor 112 for displaying the images generated by the image generating means.

Abstract: An image transmission apparatus receives a request for transmission of an image source from either one of a plurality of monitors (109 to 112) having respective inherent addresses by way of a common cable (108) via which the image transmission apparatus is connected with the plurality of monitors, analyzes both requested image source identification information indicating the requested image source and a monitor address, which are associated with the image source transmission request, refers to a storage unit (107) for storing one or more arrays each indicating a correspondence between one of a plurality of image sources and one or more monitor addresses based on analysis results, and transmits the requested image source to the monitor while adding corresponding monitor addresses to the image source.

Abstract: A host device 1 includes an NG table 10 for storing addresses specifying areas of a bulk memory 3 into which data cannot be written, a performance-guaranteed environment determination means 11 for determining whether or not the current environment of the bulk memory 3 is outside a performance-guaranteed environment where the performance of the bulk memory 3 is guaranteed, and control means 12, 13, 14, and 15 for writing data in an area of the bulk memory which is specified by an address which is not stored in the NG table 10 when the performance-guaranteed environment determination means 11 determines that the current environment is outside the performance-guaranteed environment. Therefore, even if the current environment of the bulk memory is outside the performance-guaranteed environment, the host device can normally write data in the bulk memory, thereby improving the reliability of the system.
