DISPLAY CONTROL DEVICE, DISPLAY CONTROL METHOD AND PROGRAM
First Claim
1. A display control device comprising:
- a display unit which displays data on a screen;
a proximity detection unit which detects proximity of an indicator to the screen and outputs a proximity detection signal;
a contact detection unit which detects the contact of the indicator to the screen and outputs a contact detection signal; and
a display control unit which magnifies and displays, on the basis of the proximity detection signal, a predetermined range around a proximity corresponding position or a position away from the proximity corresponding position by an approximately predetermined distance from among the data displayed on the screen, the proximity corresponding position being a position on the screen corresponding to the position of the indicator whose proximity to the screen was detected,wherein the display control unit fixes the magnified display of the predetermined range on the basis of the contact detection signal depending on the contact operation of the indicator for the predetermined range and does not change the display position of the magnified predetermined range depending on a movement operation of the indicator on the screen.

Abstract
A proximity detection unit detects the proximity of a finger to a screen and outputs a proximity detection signal. A contact detection unit detects the contact of the finger to the screen and outputs a contact detection signal. On the basis of the proximity detection signal, a display control unit magnifies and displays a predetermined range around a proximity corresponding position. On the basis of the contact detection signal depending on the contact operation of the indicator for the predetermined range, the display control unit fixes the magnified display of the predetermined range and does not change the display position of the magnified predetermined range depending on the movement operation of the finger on the screen.

10. A display control method of a display control device equipped with a display unit for displaying data on a screen, comprising the steps of:
-
detecting proximity of an indicator to the screen and outputting a proximity detection signal; magnifying and displaying, on the basis of the proximity detection signal, a predetermined range around a proximity corresponding position or a position away from the proximity corresponding position by an approximately predetermined distance from among the data displayed on the screen, wherein the proximity corresponding position is a position on the screen corresponding to the position of the indicator whose proximity was detected; detecting the contact of the indicator to the screen and outputting a contact detection signal; fixing the magnified display of the predetermined range on the basis of the contact detection signal depending on the contact operation of the indicator to the predetermined range; and unchanging the display position of the magnified predetermined range depending on the movement operation of the indicator on the screen.

11. A program for executing a method for a computer serving as a display control device equipped with a display unit for displaying data on a screen, comprising the steps of:
-
detecting proximity of an indicator to the screen and outputting a proximity detection signal; magnifying and displaying, on the basis of the proximity detection signal, a predetermined range around a proximity corresponding position or a position away from the proximity corresponding position by an approximately predetermined distance from among the data displayed on the screen, wherein the proximity corresponding position is a position on the screen corresponding to the position of the indicator whose proximity was detected; detecting the contact of the indicator to the screen and outputting a contact detection signal; fixing the magnified display of the predetermined range on the basis of the contact detection signal depending on the contact operation of the indicator to the predetermined range; and unchanging the display position of the magnified predetermined range depending on the movement operation of the indicator on the screen.
