Abstract

An information processing apparatus that can fix the position at which some of a plurality of objects are displayed, and scroll objects other than these objects in that state, using a small number of procedural steps is provided. A recognition unit recognizes that a plurality of positions have been designated on a display on which objects are displayed. Where a first position corresponding to a position at which one of a plurality of objects is displayed is recognized by the recognition unit, and a second position corresponding to a position that is located on the display and at which a designated object is not displayed is recognized by the recognition unit, a display control unit scrolls objects other than the designated object, when a movement of the second position has been detected.

Claims

1. An information processing apparatus that controls a display position of an object displayed in a display unit, the apparatus comprising:

a display unit configured to display an object;

a recognition unit configured to recognize that a plurality of positions on the display unit have been designated; and

a display control unit configured, where a first position corresponding to a position at which one of a plurality of objects is displayed is recognized by the recognition unit and a second position corresponding to a position that is located on the display unit and at which a designated object is not displayed is recognized by the recognition unit, to scroll objects other than the designated object, when a movement of the second position has been detected.

2. The information processing apparatus according to claim 1,

wherein the display control unit is further configured not to move the position at which the designated object is displayed when a movement of the first position has not been detected, and

the display control unit is further configured to move the position at which the designated object is displayed when a movement of the first position has been detected, based on an amount of movement and a direction of movement corresponding to a movement locus of the first position, regardless of an amount of movement and a direction of movement of the scroll.

4. The information processing apparatus according to claim 1,

wherein the objects are images superimposed on a background image.

5. The information processing apparatus according to claim 1,

wherein the recognition unit recognizes that said positions have been designated, in response to a user operation performed on an input unit superimposed on the display unit.

3. An information processing apparatus that controls a display position of an object displayed in a display unit, the apparatus comprising:

a display unit configured to display an object;

a recognition unit configured to recognize that a plurality of positions on the display unit have been designated; and

a display control unit configured, where a first position corresponding to a position at which one of a plurality of objects is displayed is recognized by the recognition unit and the second position corresponding to a position that is located on the display unit and at which a designated object is not displayed is recognized by the recognition unit, to scroll objects other than the designated object based on an amount of movement and a direction of movement corresponding to a movement locus of the second position, without changing a position at which the designated object is displayed, when a movement of the second position has been detected without a movement of the first position;

the display control unit being configured to move the position at which the designated object is displayed based on an amount of movement and a direction of movement corresponding to a movement locus of the first position, and to scroll objects other than the designated object based on an amount of movement and a direction of movement corresponding to a movement locus of the second position, when a movement of the first position has been detected and a movement of the second position has been detected; and

,

the display control unit being configured to move the position at which the designated object is displayed based on an amount of movement and a direction of movement according to a movement locus of the first position, without changing positions at which a plurality of objects other than the designated object are displayed on the display unit, when a movement of the first position has been detected without a movement of the second position.

6. A method for operating an information processing apparatus that controls a display position of an object displayed in a display unit, the method comprising:

a display step of displaying an object;

a recognition step of recognizing that a plurality of positions on the display unit have been designated; and

a display control step of, where a first position corresponding to a position at which one of a plurality of objects is displayed is recognized by the recognition step and a second position corresponding to a position that is located on the display unit and at which a designated object is not displayed is recognized by the recognition step, scrolling objects other than the designated object, when a movement of the second position has been detected.
