Abstract

The present invention provides an electronic device which is capable of effectively using a plurality of board information stored in the map database and reducing the information inconformity of the boards directly watched by users and the board indicated by a navigation device. In advance, the information of the guiding boards and the confirmation boards arranged with respect to the branches in the actual world are stored in a map (DB21). When the branch guiding is performed, the information of the guiding boards is compared with the information of the confirmation boards through a universal name determination portion (264). When the universal direction names exist, direction board images (SN1) used direction names of the guiding boards are made. When the universal direction names do not exist, a direction board manufacture portion (265) manufactures a direction board image (SN2) after the combination of the direction names of the guiding boards and the direction names of the confirmation boards, and a display control portion (268) displays the manufactured direction board image.

Description

technical field [0001] The present invention relates to an electronic device that displays an enlarged image of a guidance point on a route from a departure point to a destination for guidance and guidance (corresponding to Japanese: guidebook) when approaching a guidance point on a route from a departure point to a destination, and particularly relates to directions at branch points thereof The display method of the information. Background technique [0002] In a conventional navigation device, a route from a current position to a destination is searched for and guidance of the route is performed so that the user can reach the destination. At this time, for the branch point where the road branches such as an intersection, the information of the guidepost installed at the branch point is stored in the map database in advance, and the information of the guidepost is used for guidance, so that the user can recognize the direction of travel without getting lost. direction. Th...
