Abstract

An electronic device includes a magnified view window display unit configured to display a magnified view window to magnify and display an area including a first touched position, a magnified view window size change unit configured to enlarge a size of the magnified view window based on the first touched position and a second touched position when a touched position moves to the second touched position from the first touched position, and a view target area determining unit configured to determine a display target area including the second touched position corresponding to the size of the magnified view window and to display the display target area on the magnified view window.

Claims

1. An electronic device comprising:

a memory; and

a processor coupled to the memory and the processor configured to execute a process that causes the electronic device to perform;

displaying a magnified view window to magnify and display an area including a first touched position, the first touched position being a position at which a single touch operation is detected on a touch panel;

enlarging a size of the magnified view window based on the first touched position and a destination position when a single touch moving operation to move a single touch position to the destination position from the first touched position is detected; and

determining a display target area including the destination position corresponding to the size of the magnified view window and to display the display target area on the magnified view window,

wherein the determining includes associating the destination position with a predetermined position of the magnified view window,

wherein the magnified view window is displayed on upper side of the destination position on a screen and a horizontal line coordinate of the predetermined position of the magnified view window on the screen is coincident with a horizontal line coordinate of the destination touched position on the screen.

2. The electronic device according to claim 1, wherein the enlarging includes fixing a horizontal width of the magnified view window, and enlarging a vertical size thereof.

3. The electronic device according to claim 1, wherein the determining includes determining the display target area in a range enabled to be displayed on the magnified view window at a predetermined magnifying power.

4. A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute information display process comprising:

displaying a magnified view window to magnify and display an area including a first touched position, the first touched position being a position at which a single touch operation is detected on a touch panel;

enlarging a size of the magnified view window based on the first touched position and a destination position when a single touch moving operation to move a single touch position to the destination position from the first touched position; and

determining the display target area including the destination position corresponding to the size of the magnified view window and displaying the display target area in the magnified view window,

wherein the determining includes associating the destination position with a predetermined position of the magnified view window,

wherein the magnified view window is displayed on upper side of the destination position on a screen and a horizontal line coordinate of the predetermined position of the magnified view window on the screen is coincident with a horizontal line coordinate of the destination position on the screen.
