Abstract:
1. A map display apparatus for displaying a map image at a plurality of display resolutions, the apparatus comprising: an information recording unit configured to associate an image signal of a captured image generated through an imaging unit with imaging position information generated through a position information generating unit to record the associated image signal and imaging position information as image information, the imaging position information indicating the position of the imaging unit upon generation of the image signal; a map information storage unit configured to store map information for displaying the map image; a classification information recording processing unit configured to divide a map area shown by the map information into mesh cells such that different mesh cell sizes are suitable for the respective display resolutions, generate imaging classification information about classifying the image information according to the imaging position information with respect to a mesh cell to which the image information is relevant, and record the imaging classification information; and a display control unit configured to determine on each of the mesh cells on the map image, each mesh cell having a size suitable for the display resolution of the map image, on the basis of the imaging classification information whether the image information is relevant to a mesh cell, and arrange an imaging identification representation in the mesh cell determined to be relevant to the image information, the imaging identification representation indicating that the mesh cell includes an imaging location related to the captured image.
