Abstract

An information processing apparatus includes a detection unit configured to detect an operation position and an operation type of an operation performed in a display screen, and a control unit configured to display a magnified display region, which is obtained by magnifying a predetermined display region containing the operation position, based on the operation position and the operation type detected by the detection unit, and to execute, without switching the display screen, a change of a magnitude of the magnified display region, which is being displayed, or a change of a magnification ratio of screen information displayed in the magnified display region.

Claims

1. An information processing apparatus comprising:

a detection unit configured to detect an operation position and an operation type of an operation performed in a display screen; and

a control unit configured to display a magnified display region, which is obtained by magnifying a predetermined display region containing the operation position, based on the operation position and the operation type detected by the detection unit, and to execute, without switching the display screen, a change of a magnitude of the magnified display region, which is being displayed, or a change of a magnification ratio of screen information displayed in the magnified display region.

2. The information processing apparatus according to claim 1, wherein the detection unit is configured to be able to simultaneously detect a plurality of operation positions of an operation performed in the display screen and to detect information about movement of the plurality of operation positions, and

wherein, if at least one operation position of the simultaneously detected plurality of operation positions is located inside the magnified display region, the control unit changes a magnification ratio of the magnified display region according to information about movement of another operation position of the simultaneously detected plurality of operation positions.

3. The information processing apparatus according to claim 2, wherein the control unit restores the changed magnification ratio to an initial value when the display screen is switched.

4. The information processing apparatus according to claim 1, wherein the detection unit is configured to be able to simultaneously detect a plurality of operation positions of an operation performed in the display screen and to detect information about movement of the plurality of operation positions,

wherein, if at least one operation position of the simultaneously detected plurality of operation positions is located outside the magnified display region, the control unit changes a magnitude of the magnified display region according to information about movement of another operation position of the simultaneously detected plurality of operation positions, and

wherein, if all of the simultaneously detected plurality of operation positions are located inside the magnified display region, the control unit changes a magnification ratio of the magnified display region according to information about movement between the simultaneously detected plurality of operation positions.

5. The information processing apparatus according to claim 4, wherein the control unit restores the changed magnification ratio to an initial value when the display screen is switched.

6. The information processing apparatus according to claim 1, wherein the control unit hides the magnified display region, which is being displayed, when the operation type of an operation performed on the display screen or the magnified display region satisfies a predetermined hiding condition.

7. The information processing apparatus according to claim 6, wherein, when hiding the magnified display region, the control unit displays a display screen, which has been displayed immediately before the magnified display region is displayed, at a foreground.

8. A control method for an information processing apparatus including a detection unit configured to detect an operation position and an operation type of an operation performed in a display screen, the control method comprising:

displaying a magnified display region, which is obtained by magnifying a predetermined display region containing the operation position, based on the operation position and the operation type detected by the detection unit; and

executing, without switching the display screen, a change of a magnitude of the magnified display region, which is being displayed, or a change of a magnification ratio of screen information displayed in the magnified display region.

9. A computer-readable storage medium storing a computer program that causes a computer to function as an information processing apparatus comprising:

a detection unit configured to detect an operation position and an operation type of an operation performed in a display screen; and

a control unit configured to display a magnified display region, which is obtained by magnifying a predetermined display region containing the operation position, based on the operation position and the operation type detected by the detection unit, and to execute, without switching the display screen, a change of a magnitude of the magnified display region, which is being displayed, or a change of a magnification ratio of screen information displayed in the magnified display region.
