[Problem] To provide a map in which overlapping characters and the like are easily distinguished. [solution] A terminal (300) is prepared which is provided with a display capable of stereoscopic viewing by visually recognizing each of a right-eye-use image and a left-eye-use image using the right eye and the left eye, respectively. Map data (211) to be a background is generated as common image data for all areas by performing parallel projection of a 3-dimensional model stored in a 3D map database (104). At this time, by setting projection conditions which impart a parallax between the right-eye-use and left-eye-use images, it is possible to prepare right-eye-use/left-eye-use parallel projection data for all areas. With regard to characters displayed upon a map, when performing display, display depth is set on the basis of such conditions as overlapping that passes through characters, and in accordance with the same, display positions of the characters are offset to generate stereoscopic-use image data. As a result, even overlapping characters are displayed at different display depths, and therefore, it is possible to relatively easily distinguish therebetween. |
