摘要:
A vehicle navigation apparatus determines whether or not the currently traveled route having a current vehicle position matches with estimated routes after determining, on the basis of the traveled route history, the estimated routes which correspond to destination candidates. Then, the navigation apparatus further determines whether or not the subsequent portion of the estimated route overlaps with other estimated route, for selecting one of the destination candidates. The vehicle navigation apparatus thus selects the destination candidate, in a highly accurate manner in terms of user preference, based on the traveled route history.

An outline compensation circuit comprising: a first coefficient multiplier for reducing a level of an image signal by one half and reversing the polarity thereof; a first delay circuit for delaying by 2.tau. the signal from the first coefficient multiplier; a first adder for adding the signal from the first delay circuit to the image signal; a second delay circuit for delaying the signal from the first adder by 2.tau.; a second adder for adding the signal delayed by the second delay circuit to the signal from the first coefficient multiplier to output a second-order differential signal of the image signal; a first non-linear converter for calculating the square root of the second-order differential signal from the second adder; a subtractor for subtracting the signal from the first delay circuit from the signal from the first coefficient multiplier to output a first-order differential signal of the image signal; an absolute value calculating circuit for calculating the absolute value of the first-order differential signal from the subtractor; a third delay circuit for delaying the signal from the absolute value calculating circuit by .tau.; a second non-linear converter for calculating the square root of the signal from the third delay circuit; and a multiplier for multiplying the signal from the second non-linear converter with the signal from the non-linear converter to output an outline compensation signal, whereby outline compensation can be carried out naturally.
摘要:
A display is divided into two regions, a standard region and an enlarged region with a user positioned is at an angle relative to the display. The standard region is formed on a side nearer the user and the enlarged region is formed on a side farther from the user. When the navigation device displays guidance information, information displayed in the standard region is displayed on a standard scale, while information displayed in the enlarged region is displayed enlarged relative to the standard scale. Since the display on the side farther from the user position is thus enlarged, the user can more easily view that guidance information.

A navigation device that is provided with reference databases that include search databases that are referenced when the navigation device performs a location search for a location on a map, that accepts provided update data, and that performs update processing for the reference databases is provided with a priority processing unit that, in a case where a command to perform the location search is input during the update processing for the reference databases, gives priority to performing the update processing for location data that are stored in the search databases, as well as with a search unit that, after the update processing for the location data is completed by the priority processing unit, is enabled to perform the location search using the updated location data.

Search devices, methods, and programs input a plurality of search terms that are associated with search objects and set a search condition for the input search terms. The devices, methods, and programs calculate an approximate number of the search objects that correspond to the set search condition and output the search objects that correspond to the set search condition as search results. The devices, methods, and programs display the calculated approximate number of the search objects until the search results are output. One or more of the output search objects may be used as a destination by a navigation device.
摘要:
The present invention enables accurate setting of a road as a driving route by reading the scale of a map displayed on a map screen, reading matching target roads correlated with the scale of the map. The matching target roads are used for setting a driving route. A determination is made whether or not a road has been specified by an operator and, if a locus of road has been specified by the operator, one of the matching target roads nearest to the specified locus is used for setting the driving route.
