Abstract

An apparatus for displaying content stored as a plurality of pages is provided. The apparatus comprises a detection unit configured to detect a first user operation and a control unit configured to send signals to display one of the plurality of pages on a screen. The control unit is further configured to, when the detected first user operation comprises a page turn instruction, send signals to sequentially change the displayed page at a first rate when the displayed page is outside a first number of pages before or after a first marked page and sequentially change the displayed page at a second rate slower than the first rate when the displayed page is within the first number of pages before or after the first marked page.

Claims

1. An apparatus for displaying content stored as a plurality of pages, comprising:

a defection unit configured to detect a first user operation; and

a control unit configured to;

send signals to display one of the plurality of pages on a screen; and

when the detected first user operation comprises a page turn instruction;

send signals to sequentially change the displayed page at a first rate when the displayed page is outside a first number of pages before or after a first marked page; and

sequentially change the displayed page at a second rate slower than the first rate when the displayed page is within the first number of pages before or after the first marked page.

2. The apparatus according to claim 1, wherein the second rate is a rate at which the displayed page does not change until a second user operation is detected.

3. The apparatus according to claim 1, wherein the control unit is further configured to send signals to display a visual mark corresponding to the first marked page.

4. The apparatus according to claim 3, wherein the visual mark includes a visual representation of at least one of a bookmark, a page corner fold, or a sticky note.

5. The apparatus according to claim 1, wherein the detection unit is further configured to detect the first user operation via a touch screen.

6. The apparatus according to claim 5, wherein the control unit is further configured to send signals to display a page selection region on the touch screen and the detection unit is configured to detect a touch operation in the page selection region as the first-user operation.

7. The apparatus according to claim 6, wherein the detection unit is further configured to detect a sliding motion of a user control member as the first user operation.

8. The apparatus of claim 7, wherein the user control member comprises at least one of a finger, a stylus, or a pen.

9. The apparatus of claim 1, wherein the detection unit is configured to detect the first user operation via at least one of a button, a mouse, a trackball, a touchpad, a lever, a joystick, or a switch.

10. The apparatus of claim 1, wherein control unit is further configured to mark the first marked page in response to a touch operation made by the user.

11. The apparatus of claim 1, wherein the detection unit is further configured to determine whether or not the first user operation comprises a page turn instruction or a mark operation for marking a second marked page.

12. The apparatus of claim 11, wherein the control unit is further configured to send signals to mark the second marked page when the first user operation is a mark operation.

13. The apparatus of claim 11, wherein the detection unit is further configured to:

determine that a first touch operation has occurred by detecting the user control member within a proximity region;

detect whether or not the user control member exits the proximity region after the first touch operation;

determine that the first user operation comprises a page turn instruction when user control member exit of the proximity region is detected;

determine whether or not a second touch operation has occurred when user control member exit of the proximity region is not detected for a period of time after the first touch operation has occurred; and

determine that the first user operation comprises a mark operation when the second touch operation has occurred.

14. The apparatus of claim 1, wherein the control unit is further configured to, when the first user operation comprises a page turn instruction:

send signals to sequentially change the displayed page at a third rate when the displayed page is outside a second number of pages before or after a second marked page; and

sequentially change the displayed page at a fourth rate slower than the third rate when the displayed page is within the second number of pages before or after the second marked page.

15. The apparatus of claim 14, wherein the third rate is equal to the first rate and the fourth rate is equal to the second rate.

16. The apparatus of claim 14, wherein the first number of pages is equal to the second number of pages.

17. The apparatus of claim 14, wherein the control unit is further configured to send signals to display a first visual mark corresponding to the first marked page and a second, visual mark corresponding to the second marked page.

18. The apparatus of claim 17, wherein the first visual mark comprises a first color and the second visual mark comprises a second color, the first and second colors being different.

19. A method comprising:

detecting a first user operation;

displaying one of a plurality of pages of content on a screen;

when the detected first user operation comprises a page turn instruction;

sequentially changing the displayed page at a first rate when the displayed page is outside a first number of pages before or after the marked page; and

sequentially changing the displayed page at a second rate slower than the first rate when the displayed page is within the first number of pages before or after the marked page.

20. A tangibly embodied non-transitory computer-readable medium storing instructions which, when executed by a processor, perform a method comprising:

detecting a first user operation;

displaying one of a plurality of pages of content on a screen;

when the detected first user operation comprises a page torn instruction;

sequentially changing the displayed page at a first rate when the displayed page is outside a first number of pages before or after the marked page; and

sequentially changing the displayed page at a second rate slower than the first rate when the displayed page is within the first number of pages before or after the marked page.
