Abstract

According to one embodiment, an information processing apparatus includes a display device, a touch panel located on a screen of the display device, a sensing module which senses that a particular touch operation is performed on the touch panel, an enlarged display module which enlarges a partial image in a display image determined based on a position where the particular touch operation is performed when the sensing module detects the particular touch operation, and a touch operation control module which accepts a touch operation by correcting a position of the touch operation on the partial image enlarged by the enlarged display module to a position on the display image and which cancels enlarged display performed by the enlarged display module, when the touch operation is performed in an area on the touch panel corresponding to a display area of the partial image enlarged by the enlarged display module.

Claims

1. An information processing apparatus comprising:

a display device;

a touch panel located on a screen of the display device;

a sensing module configured to sense that a particular touch operation is performed on the touch panel;

an enlarged display module configured to enlarge a partial image in a display image determined based on a position where the particular touch operation is performed when the sensing module detects the particular touch operation; and

a touch operation control module configured to accept a touch operation by correcting a position of the touch operation on the partial image enlarged by the enlarged display module to a position on the display image and to cancel enlarged display performed by the enlarged display module, when the touch operation is performed in an area on the touch panel corresponding to a display area of the partial image enlarged by the enlarged display module.

2. The apparatus of claim 1, further comprising a user interface module configured to register programs for invalidating the enlarged display of the partial image performed by the enlarged display module when the sensing module senses the particular touch operation, the programs being configured to accept the particular touch operation.

3. The apparatus of claim 2, wherein the user interface module is configured to set the type of touch operation to be sensed by the sensing module provided that the particular touch operation is performed.

4. The apparatus of claim 2, wherein the user interface module is configured to set an enlargement rate for enlarged display of the partial image performed by the enlarged display module.

5. The apparatus of claim 1, wherein the particular touch operation comprises a touch operation performed with a plurality of fingers.

6. The apparatus of claim 1, wherein the particular touch operation comprises a touch operation with another touch operation performed at a preset position on the touch panel.

7. The apparatus of claim 1, further comprising a keyboard,

wherein the particular touch operation comprises a touch operation with a depression operation of a predetermined key on the keyboard.

8. The apparatus of claim 1, further comprising a hard button,

wherein the particular touch operation comprises a touch operation with a depression operation of the hard button.

9. The apparatus of claim 1, wherein the touch operation control module is configured to move an area in the display image corresponding to a target for enlarged display of the partial image performed by the enlarged display module to a sliding direction of a sliding operation, when the sliding operation is performed such that a straight line is drawn, with two fingers, in an area on the touch panel corresponding to the display area of the partial image enlarged by the enlarged display module.

10. The apparatus of claim 1, wherein the touch operation control module is configured to enlarge the display area of the partial image enlarged by the enlarged display module or to increase the enlargement rate of the partial image displayed in the display area, when a sliding operation is performed such that two fingers are open in an area on the touch panel corresponding to the display area of the partial image enlarged by the enlarged display module.

11. The apparatus of claim 1, wherein the enlarged display module is configured to determine the enlargement rate of the partial image based on the size of an operational object located on the partial image to be enlarged.

12. The apparatus of claim 1, wherein the touch operation control module is configured to accept a touch operation and to cancel enlarged display when the touch operation is performed on the operational object located on the partial image to be enlarged.

13. A non-transitory computer readable medium having stored thereon a computer program which is executable by a computer comprising a display device and a touch panel located on a screen of the display device to execute a method of touch operation support, the computer program controls the computer to execute function of:

sensing that a particular touch operation is performed on the touch panel;

enlarging a partial image in a display image determined based on a position where the particular touch operation is performed when the particular touch operation is sensed; and

accepting a touch operation by correcting a position of the touch operation on the enlarged partial image to a position on the display image and cancelling the enlarged display of the partial image when the touch operation is performed in an area on the touch panel corresponding to the display area of the enlarged partial image.
