Road landscape data are read from the map database to obtain the representative points of respective squares from this road landscape data (S12). Straight distances from the viewpoint to the respective squares are calculated (S13). A road landscape seen from the viewpoint is displayed (S14). Density is decided on the basis of the relation of a density value previously decided in proportion to the distance from the viewpoint calculated on a read landscape display such as a relation between the distance from the viewpoint and the gradation (S15).  Then, each square to be displayed is divided into seven pieces in accordance with the distance from the viewpoint to display this side to be the brightest and a remote side to be successively darkened.

Abstract: PURPOSE:To efficiently detect the break of a liner electrode. CONSTITUTION:Probe electrodes P1 to P4 are arranged to cross each other separatedly in grade, in order to examine the wire break of liner electrodes E1 to E5. Also, capacitive coupling is applied to each crossing point of the electrodes E1 to E5, and P1 to P5.

In this case, a voltage detecting selector circuit 50 is selected to connect the left end of the electrode E3 to a detection circuit 100, while the left ends of other liner electrodes are grounded. The circuit 100 judges that no wire break exists, if no voltage fluctuation is observed at the left end of the electrode E3, and that a wire break exists, if the voltage fluctuation is observed. According to this construction, a wire break can be detected for all zones of the electrodes E1 to E5 on the operation of the circuits 40 and 50.
