Map display having scaling factors on the display and selecting scaling factors by touch sense
First Claim
1. A map display apparatus that displays a map, comprising:
- a display device;
a touch panel disposed over a screen at the display device; and
a control device that controls display at the display device with a signal input from the touch panel, wherein;
the control device displays at the display device a map and a plurality of buttons respectively designating a plurality of scaling factors that have smaller values than a scaling factor of the map and correspond to wider-area maps than the map, makes a decision as to whether or not the touch panel has been pressed at a position corresponding to one of the plurality of buttons, makes a decision as to whether or not a finger having pressed the touch panel at the position corresponding to one of the plurality of buttons respectively designating the plurality of scaling factors has been moved to a display position of the map while pressing the touch panel, and displays a wide-area map at a scaling factor designated to the one of the plurality of buttons pressed by the finger, over a part of an area where the map is displayed while sustaining the scaling factor of the map unchanged if the finger having pressed the touch panel is judged to have been moved to the display position of the map.

Abstract
A map display apparatus that displays a map includes: a display device; a touch panel disposed over a screen at the display device; and a control device that controls display at the display device with a signal input from the touch panel, and: the control device displays at the display device a map and a plurality of buttons used to adjust a scaling factor of the map, makes a decision as to whether or not the touch panel has been pressed at a position corresponding to one of the plurality of buttons, makes a decision as to whether or not a finger having pressed the touch panel has been moved to a specific position and displays, together with the map, a wide-area map at a scaling factor smaller than the scaling factor of the map if the finger having pressed the touch panel is judged to have been moved to the specific position.

7. A map display apparatus that displays a map, comprising:
-
a display device; a touch panel disposed over a screen at the display device; and a control device that controls display at the display device with a signal input from the touch panel, wherein; the control device displays at the display device a map and a plurality of buttons respectively designating a plurality of scaling factors that have smaller values than a scaling factor of the map and correspond to wider-area maps than the map, makes a decision as to whether or not the touch panel has been pressed at a position corresponding to one of the plurality of buttons, makes a decision as to whether or not the one of the buttons has been pressed over a predetermined length of time or longer or twice or more in succession, and whether or not a finger having pressed the touch panel at the position corresponding to one of the plurality of buttons respectively designating the plurality of scaling factors has been moved to a display position of the map while pressing the touch panel, displays the map by adjusting the scaling factor of the map to the scaling factor designated to the pressed button upon deciding that the one of the buttons has been pressed over the predetermined length of time or longer or twice or more in succession, and displays a wide-area map at a scaling factor designated to the one of the plurality of buttons pressed by the finger, over a part of an area where the map is displayed while sustaining the scaling factor of the map unchanged upon deciding that the finger having pressed the touch panel has been moved to the display position of the map.

8. A map display method for displaying a map at a display device that includes a touch panel disposed over a screen thereof, comprising:
-
displaying a map and a plurality of buttons respectively designating a plurality of scaling factors that have smaller values than a scaling factor of the map and correspond to wider-area maps than the map; making a decision as to whether or not a position on the touch panel corresponding to one of the plurality of buttons has been pressed and a finger having pressed the position on the touch panel has been moved to a display position of the map while pressing the touch panel; and displaying a wide-area map at a scaling factor smaller than a scaling factor designated to the one of the plurality of buttons pressed by the finger, over a part of an area where the map is displayed while sustaining the scaling factor of the map unchanged upon deciding that the finger having pressed the position on the touch panel has been moved to the display position of the map.
