A travel route display system executes a searching step of searching a database based on a given search condition; a numerical data calculating step of executing a predetermined calculation on a result obtained at the searching step to calculate numerical data displayed together with a travel route; an image data generating step of generating a plurality of kinds of image data for displaying the travel route on a screen, the generation being based on results obtained at the searching and calculating steps; a display image controlling step of so controlling the plurality of kinds of image data that an individual piece of image data or a synthesis of a plurality of image data can be displayed on the same screen, the plurality of kinds of image data being obtained at the generating step; and an image data displaying step of displaying the image data controlled at the controlling step.

Travel route display system

A map drawing apparatus has a map information reading section, a level extracting section, and a map information processing section. The map information reading section reads map information. The level extracting section extracts a level of a spectrum over a predetermined frequency range from a signal of input sound. The map information processing section processes the form (height, color, shape) of an object (a building, a cloud in the background, or the like) contained in the map information read by the map information reading section, into map information dynamically changed in cooperation with the spectrum extracted by the level extracting section. The map information processing section converts the processed map information into an image signal that can be displayed on a display device.
