Abstract: A method of displaying information on a display of a handheld electronic device includes steps of determining a target area onscreen to be visually magnified and causing a shape-changing zone of the display to change shape in the target area to visually magnify information displayed in the target area. The array of shape-changing zones on the touch-sensitive display can be independently actuated to form a magnifying lens over any onscreen object of interest. For example, this lens can be used to magnify a selected portion of a map, a portion of text or a specific point of interest. The lens can be used to magnify a route displayed on a map, or simply to zoom in on the current location of the device as displayed onscreen.

Abstract: A display screen indicates a map on a first scale. After a vehicle passes a guide point, determinations are made as to whether or not an on-map position of a next guide point is outside a predetermined large-area indication deciding frame in the display screen, and as to whether or not the on-map position of the next guide point is inside a predetermined detailed indication deciding frame in the display screen. A second scale in a range where the current position of the vehicle and the on-map position of the next guide point are in the display screen is computed in response to results of the determinations. The display screen successively indicates the map on the first scale, maps on different intermediate scales between the first and second scales, and a map on the second scale in either a reducing order or a magnifying order at prescribed time intervals.

Abstract: When a user pushes a scroll-direction key, an ECU obtains, from a memory, a division map corresponding to a division located in a direction designated by the scroll-direction key. The ECU then outputs the division map to a display controller. The display controller compresses the division map to store in a VRAM. At scrolling a displayed image, the display controller expands the compressed division map. It then outputs, to an image signal generator, only a necessary portion of the expanded division map. Thereby, the displayed image can be scrolled at high speed and easily recognizable for the user.
