Display control device, display control method and program
View Patent ↗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.
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.
2. The display control device according to claim 1 , wherein, in response to the releasing the fixing of the position of the predetermined region, the display controller moves the position of the predetermined region instantaneously to a position on the screen corresponding to the position of the indicator.
3. The display control device according to claim 1 , wherein, in response to the releasing the fixing of the position of the position of the predetermined region, the display controller moves the position of the predetermined region at a uniform speed or at a nearly uniform speed from the fixed position to a position on the screen corresponding to the position of the indicator.
4. The display control device according to claim 1 , wherein, in response to the release of the releasing the fixing of the position of the predetermined region, the display controller moves the position of the predetermined region with acceleration from the fixed position to a position on the screen corresponding to the position of the indicator.
5. The display control device according to claim 1 , wherein the position on the screen corresponding to the position of the indicator is a coordinate projecting the position of the indicator on the screen.
6. The display control device according to claim 1 , wherein the position on the screen corresponding to the position of the indicator is a position spaced from a coordinate projecting the position of the indicator on the screen by a predetermined distance.
7. The display control device according to claim 1 , wherein the predetermined region includes a first display area having a magnification display ratio larger than a predetermined value and a second display area having a magnification display ratio smaller than the predetermined value.
8. A display control method comprising:
detecting contact of an indicator with a screen;
detecting 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; magnifying an image of a predetermined region on the screen when at least one of the proximity and the contact is detected; moving a position of the predetermined region according to a change in a position of the indicator while the proximity is detected; and fixing the position of the predetermined region, regardless of a change in the position of the indicator, while the detected contact is continuously maintained;
releasing 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.
9. A non-transitory computer readable recording medium storing a program that causes a computer to perform operations comprising: detecting contact of an indicator with a screen; detecting 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; magnifying an image of a predetermined region on the screen when at least one of the proximity and the contact is detected; moving a position of the predetermined region to according to a change in a position of the indicator while the proximity is detected; and fixing the position of the predetermined region, regardless of a change in the position of the indicator while the detected contact is continuously maintained;
releasing 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.
