Abstract

PURPOSE:To obtain an easily observable display independently of the peripheral brightness of a vehicle by arranging plural tables setting up the color arrangement and brightness of a picture on a display means in accordance with the peripheral brightness of the vehicle and selectively displaying a map with the color arrangement and brightness of the tables. CONSTITUTION:When the speed and advancing direction of a vehicle are input ted respectively from a speed sensor 11 and an azimuth sensor 12, the current position of the vehicle is calculated. Then peripheral map data specified map data around the current position and a driver through an input means 2 are read out from an auxiliary storage means 3, the display shape, position, etc., of the data are analyzed and color information corresponding to the code of road information in the map data is read out by selectively referring the display color corresponding tables 441 to 443 with color arrangement and brightness specified by the input means 20. Consequently, an easily observable display can be obtained independently of its peripheral brightness.
