Display control device, display control method and program
First Claim
1. A display control device comprising:
- a contact detector that detects contact of an indicator with a screen;
a proximity detector that detects a proximity of the indicator to the screen, when the contact is not detected and when a distance between the indicator and the screen is smaller than a predetermined value; and
a display controller that magnifies an image of a predetermined region on the screen when at least one of the proximity and the contact is detected, wherein the display controller moves a position of the predetermined region according to a change in a position of the indicator while the proximity is detected, and the display controller fixes the position of the predetermined region, regardless of a change in the position of the indicator while the contact detected by the contact detector is continuously maintained,wherein the display controller releases the fixing of the position of the predetermined region, when the proximity of the indicator to the screen is detected while the position of the predetermined region is fixed,wherein the predetermined region has one of a circular shape, an elliptical shape and a quadrangular shape.

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.
