Abstract: A vehicle-in-question position detection unit (41) detects the position of the vehicle in question on the basis of GPS data acquired from a GPS receiver (3). An aerial photograph recording unit (43) records aerial photographs corresponding to the position of the vehicle in question. A peripheral object detection unit (42) produces a distance map on the basis of distance measurement data indicating the distance between a peripheral object and the vehicle in question obtained by a distance measurement sensor (2) mounted in the vehicle in question scanning the periphery. A peripheral map generation unit (44) updates past aerial photographs obtained from the aerial photograph recording unit (43) on the basis of the distance map, producing the latest peripheral map. The display device (5) displays the latest peripheral map at a screen.

Abstract: A camera-orientation estimation unit estimates the amount of change in camera orientation on the basis of vehicle speed changes obtained from a vehicle-information acquirer. A distance-information update decision unit decides, on the basis of the amount of change in camera orientation, whether to update distance information by computing new distance information in a distance-computation unit or to update distance information using distance information stored in a distance-information memory unit. If the distance-information update decision unit has decided to update distance information by computing new distance information, a display device displays distance information that the distance-computation unit computes from a real-time image. If the distance-information update decision unit has decided to update using past stored distance information, the display device displays past distance information read from the distance-information memory unit.

Abstract: On the basis of the illumination output from the illumination estimation unit (3), a necessary image storage time calculation unit (4) calculates the time required for storing the image in order to acquire the contrast to make image recognition possible. A possible image storage time calculation unit (8) calculates a time in which image storage is feasible using the vehicle speed acquired from a vehicle information acquisition section (7). A recognition possibility determination unit (5) compares the required image storage time and the feasible image storage time, and determines whether or not it is possible to carry out image recognition. If the recognition possibility determination unit (5) determines that recognition is possible, a synthesis of the acquired image data is accumulated/superimposed to generate an image with improved contrast that is displayed on a display device (11).

Abstract: On the basis of the illumination output from the illumination estimation unit (3), a unit (4) for calculating a required image storage time calculates the time required for storing the image in order to acquire the contrast to make image recognition possible. A unit (8) for calculating a feasible image storage time calculates a time in which image storage is feasible using the vehicle speed acquired from a vehicle information acquisition means (7). A recognition possibility determination unit (5) compares the required image storage time and the feasible image storage time, and determines whether or not it is possible to carry out image recognition. If the recognition possibility determination unit (5) determines that recognition is possible, a synthesis of the acquired image data is accumulated/superimposed to generate an image with improved contrast, and said image is displayed on a display means (11).

Abstract: Said device can thereby accurately output the distance to a target abject. A camera-orientation estimation unit (4) estimates the amount of change in camera orientation on the basis of vehicle speed changes obtained from a vehicle-information acquisition means (2). A distance-information update decision unit (5) decides, on the basis of the amount of change in camera orientation, whether to update distance information by computing new distance information in a distance-computation unit (7) or to update distance information using distance information stored in a distance-information memory unit. If the distance-information update decision unit (5) has decided to update distance information by computing new distance information, a display means (9) displays distance information that the distance-computation unit (7) computes from a real-time image.

Abstract: A touch location detection section (103) detects the location on a display screen where the operator's finger touches. A transfer length calculation section (104) calculates the transfer length La of the operator's finger from the touch start location S to the touch end location E. A transfer length judgment section (105) judges whether or not the transfer length La is greater than a reference transfer length Ls. A location shift calculation section (106) calculates the location shift ? of the operator's finger. A location shift judgment section (107) judges whether or not the location shift ? is less than a predetermined reference location shift ?s. When La>Ls and ?<?s, a screen split control section (108) controls the operation of an image display section so as to split a display screen 101.

Abstract: A terminal device for reading a cartographic file in which updating one cartographic file does not require updating cartographic files in the neighboring units. For this purpose, cartographic files which represent respective units extracted by dividing a map into a plurality of areas each comprise node records generated for respective nodes and link records generated for respective links. Given node records contain coordinate information about neighboring nodes which define connections of roads between its unit and a neighboring unit. The cartographic files are stored in a first storage device. The data processing portion executes a process of searching for a route by using the cartographic files. During the route search, the data processing portion traces the connection from a road in one unit to a road in another, neighboring, unit on the basis of the coordinate information about the neighboring nodes of said one unit and said neighboring another unit.

Abstract: The present invention provides a digital data transmitting/receiving method, a base station unit, and a mobile object terminal unit, which enable collection of information desired by the mobile object terminal among service information distributed by the base station by using a broadcasting channel. The base station transmits data after identification information is added in the header information of the service information provided to the mobile object terminal, and the mobile object terminal has an address showing the identification information. The mobile object terminal analyzes the identification information by indicating the address to identify whether the service information is provided to the terminal.

Abstract: In an information terminal device, a processor receives route information on a route from a start point to a destination and guidance information required for route guidance, in accordance with a standard communications protocol. The processor guides the route from the start point to the destination through an information presentation part by using first cartographic data having a basis on the received route information and the guidance information. The processor requests, as required, a specific information service center for point information in a tag format showing details of each important point (POI) on the route through an information request part. As a result, the processor receives the point information on the important point from the information service center in accordance with the standard communications protocol.

Abstract: A base station transmits map information in which a predetermined area is divided in rectangular areas and represented on several steps of scales by using a broadcast channel. The user of a terminal device enters scale and area of map information currently required. The terminal device stores only the map information of the area and scale that the user requires among a plurality of pieces of map information transmitted on the broadcast channel in an internal map storage portion. Thus a map information providing method and a terminal device used in the method are provided, wherein the terminal device can select required information from among the map information transmitted from the base station.
