a display control unit configured to, in a case where the target position is different from the position acquired by the layout acquiring unit, display the object that has been displayed at the target position on the display screen before the update at the estimated target position on the display screen after the update.

2. The information processing apparatus according to claim 1, wherein

the target position is determined based on a touch with an indicator at a position on a touch panel display displaying the display screen;

and

the estimating unit estimates the target position based on a position on the touch panel display to which the indicator is brought close.

3. The information processing apparatus according to claim 1, wherein

the target position is determined based on moving off of an indicator having touched the touch panel display displaying the display screen from the touch panel display;

and

the estimating unit estimates the target position based on a position on the touch panel display touched by the indicator.

4. The information processing apparatus according to claim 1, wherein

the target position is determined based on a touch with a mouse click input to the display screen;

and

the estimating unit estimates the target position based on a display position of a mouse cursor to be designated on the display screen.

5. The information processing apparatus according to claim 1, wherein the estimating unit estimates a position estimated as being gazed by a user as the target position on the display screen based on a result of detection of the line of sight of the user.

6. The information processing apparatus according to claim 1, further comprising an identifying unit configured to identify an object displayed at the target position, which is estimated by the estimating unit, in an image displayed on the display screen, wherein

the display control unit, also after the update, displays the object identified by the identifying unit at the target position estimated by the estimating unit.

7. The information processing apparatus according to claim 6, further comprising an executing unit configured to execute an operation associated with an object displayed at the determined target position on the display screen in response to the determination of the target position by a user operation.

8. The information processing apparatus according to claim 1, wherein the display control unit displays the object displayed at the target position estimated by the estimating unit at an identical position on a display screen before the update and a display screen after the update.

9. The information processing apparatus according to claim 1, wherein the receiving unit receives an update instruction occurring in response to an increase or decrease of contents of an image displayed on the display screen.

10. The information processing apparatus according to claim 1, wherein the display control unit overlaps on a display screen before the update a range where an object displayed at the target position estimated by the estimating unit is displayed and a range where an object is displayed on the display screen after the update.

11. The information processing apparatus according to claim 1, further comprising a moving amount determining unit configured to determine an amount of movement for translating an image to be displayed on the display screen after the screen update based on the target position estimated by the estimating unit and the layout acquired by the layout acquiring unit, wherein

the display control unit displays an image on the display screen after the update by translating it by an amount of movement determined by the moving amount determining unit from a predetermined display position.

12. The information processing apparatus according to claim 1, further comprising an identifying unit configured to identify an object present near the target position estimated by the estimating unit in an image displayed on the display screen, wherein

the moving amount determining unit determines the amount of movement such that the target position estimated by the estimating unit may be positioned at a center of a region where an object identified by the identifying unit is to be displayed in an image to be displayed on the display screen after the screen update.

13. The information processing apparatus according to claim 1, wherein the moving amount determining unit determines the amount of movement such that a positional correlation on the display screen before the update between the target position estimated by the estimating unit and an object identified by the identifying unit may be maintained also on the display screen after the update.

14. The information processing apparatus according to claim 1, wherein the moving amount determining unit determines an amount of movement for translating an image to be displayed on the display screen after the update such that the target position estimated by the estimating unit may be contained in a region where an object identified by the identifying unit is to be displayed.

15. The information processing apparatus according to claim 1, further comprising a probability acquiring unit configured to acquire a probability that at least one object displayed on the display screen will be operated based on the target position estimated by the estimating unit, wherein

the identifying unit identifies an object based on the probability acquired by the probability acquiring unit.

16. The information processing apparatus according to claim 1, wherein, in a case where an object to be displayed at the target position estimated by the estimating unit in an image to be displayed on the display screen is a complex object including a plurality of sub-objects,

the display control unit displays a sub-object displayed at the target position estimated by the estimating unit among the plurality of sub-objects at an identical position after the update and before the update.

17. The information processing apparatus according to claim 1, wherein an image displayed on the display screen is a Web page displayed on an execution screen of a Web browser application;

and

the receiving unit receives an update instruction to update at least a part of the Web page displayed by using data newly received in a rendering process executed by the Web browser application while acquiring data over the Internet.

18. The information processing apparatus according to claim 1, wherein the update instruction occurs independently and asynchronously with the user operation.

19. A method for controlling an information processing apparatus, the method comprising:

receiving an update instruction to update at least a part of an image displayed on a display screen;

estimating a target position on the display screen before designation of the target position on the display screen by a user operation;

acquiring a position of an object to be laid out within the image on the display screen after the update, the object being displayed at the target position on the display screen before the update, in a case where an image displayed on the display screen is updated in response to the update instruction received by the receiving unit after the estimating unit estimates the target position; and

in a case where the target position is different from the position acquired, displaying the object that has been displayed at the target position on the display screen before the update at the estimated target position on the display screen after the update.
