Abstract

A display device includes a display section which displays an image in a screen, a proximity detecting section which detects proximity of a finger to the screen, an image generating section which generates, in accordance with the detected proximity of the finger, an enlarged image by enlarging the image displayed in the screen with a prescribed enlarged display magnification, and a display control section which controls to display a local enlarged image corresponding to a part of the generated enlarged image in a superimposed manner over the image in a position in the screen vertically below the finger whose proximity has been detected

Claims

1. A display device comprising:

a display section which displays an image in a screen;

a proximity detecting section which detects proximity of a finger to the screen;

an image generating section which generates, in accordance with the detected proximity of the finger, an enlarged image by enlarging the image displayed in the screen with a prescribed enlarged display magnification; and

a display control section which controls to display a local enlarged image corresponding to a part of the generated enlarged image in a superimposed manner over the image in a position in the screen vertically below the finger whose proximity has been detected.

2. The display device according to claim 1, wherein the proximity detecting section detects movement of the finger substantially parallel to the screen from a position where the proximity of the finger has been detected;

and

wherein in accordance with a distance of the movement of the finger substantially parallel to the screen from the position where the proximity of the finger has been detected, the display control section controls to display the local enlarged image, which is obtained by moving the enlarged image having been displayed in the superimposed manner on the basis of the prescribed enlarged display magnification and the distance of the movement, in a superimposed manner over the image.

3. The display device according to claim 1, further comprising:

a touch detecting section which detects a touch with the finger on the screen; and

an operation executing section which allocates an item of a specific portion in the image displayed in the screen to start of a prescribed operation,

wherein the operation executing section executes the prescribed operation in the case where a position of the detected touch with the finger corresponds to a position of the item of the specific portion displayed in the local enlarged image.

4. The display device according to claim 1, wherein the display control section changes the local enlarged image displayed in the superimposed manner over the image to the image to be displayed in the screen if the proximity of the finger is not detected any more after detecting the proximity of the finger.

5. The display device according to claim 1, wherein the proximity detecting section detects a distance between the finger whose proximity has been detected and the screen;

and

wherein the image generating section generates the enlarged image with the prescribed enlarged display magnification varied in accordance with the distance.

6. The display device according to claim 3, wherein the operation executing section executes the prescribed operation allocated to the item in a state where the local enlarged image is not displayed in response to detection of a touch with the finger to the item displayed in the image in the case where the image and the local enlarged image are displayed in a superimposed manner in the screen.

7. A display control method performed in a display device, comprising the steps of:

displaying an image in a screen;

detecting proximity of a finger to the screen;

generating an enlarged imaged by enlarging the image displayed in the screen with a prescribed enlarged display magnification in accordance with the detected proximity of the finger; and

displaying a local enlarged image corresponding to a part of the generated enlarged image in a superimposed manner over the image in a position in the screen vertically below the finger whose proximity has been detected.

8. A program for causing a computer executing as a display device to realize:

a step of displaying an image in a screen;

a step of detecting proximity of a finger to the screen;

a step of generating an enlarged imaged by enlarging the image displayed in the screen with a prescribed enlarged display magnification in accordance with the detected proximity of the finger; and

a step of displaying a local enlarged image corresponding to a part of the generated enlarged image in a superimposed manner over the image in a position in the screen vertically below the finger whose proximity has been detected.
