P To provide a map display apparatus and a map display system for allowing a user to easily enlarge or reduction a map in an area of interest and easily obtain relation with peripheral areas. PSOLUTION: An inclination value measurement part 113, a client control part 114 and a client transmitting/receiving part 115 are mainly formed in a portable terminal 110. The inclination value measurement part 113 configures a state detection part and an inclination sensor is used. The inclination measurement part 113 continuously measures a roll value ro and a pitch value pi of the portable terminal 110. The client control part 114 selects an X coordinate xfi from X coordinate candidates Xf according to the size of the pitch value pi and selects a Y coordinate yfi from Y coordinate candidates Yf according to the size of the roll value ro. The client control part 114 moves the center of a focus area to the coordinates (xfi and yfi) ON a display part 111. PCOPYRIGHT: (C)2010 and JPO& INPIT
