Abstract

The electronic device includes a main body, a display screen, a first block plate, a first image capturing unit, a second image capturing unit, an image analysis unit and a control unit. The first image capturing unit is used for capturing a book image of the book and a first eye image of an eye. The second image capturing unit is used capturing a second eye image of the eye. The image analysis unit is used for determining a relative distance between the eye and the main body according to the first eye image and the second eye image and a book size of the book according to the book image. The control unit is used for determining a suitable viewing angle and controlling the display screen to rotate, such that a viewing angle at the book viewed by the eye is substantially equal to the suitable viewing angle.

First claim

What is claimed is:

1. An electronic device, comprising:
a main body;
a display screen, pivotally connected to the main body;
a first block plate, pivotally connected to the main body for making a book lean against between the first block plate and the display screen;
a first image capturing unit, disposed on the display screen for capturing a book image of the book and a first eye image of an eye;
a second image capturing unit, disposed on the main body for capturing a second eye image of the eye;
an image analysis unit, used for determining a relative distance between the eye and the main body according to the first eye image and the second eye image and a book size of the book according to the book image; and
a control unit, used for determining a suitable viewing angle according to the relative distance and the book size and controlling the display screen to rotate, such that a viewing angle at the book viewed by the eye is substantially equal to the suitable viewing angle.

2. The electronic device according to claim 1 , wherein the control unit is used for controlling the first block plate to rotate for driving the first block plate to project from the main body.

3. The electronic device according to claim 1 , wherein the first block plate comprises:
a first plate; and
a second plate;
wherein one of the first plate and the second plate is pivotally connected to the main body, and the control unit is used for controlling another of the first plate and the second plate to rotate for driving the first block plate to project from the main body.

4. The electronic device according to claim 1 , wherein a rotating axis of the display screen is substantially parallel to a rotating axis of the first block plate.

5. The electronic device according to claim 1 , wherein a rotating axis of the display screen is substantially perpendicular to a rotating axis of the first block plate.

6. The electronic device according to claim 1 , further comprising:
a second block plate, pivotally connected to the main body and being movable with respect to the first block plate.

7. The electronic device according to claim 6 , wherein the further comprising:
a pushing mechanism, comprising:
a first bar, comprising a first end and a second end, wherein the first end is pivotally connected to the first block plate;
a second bar, comprising a third end and a fourth end, wherein the third end is pivotally connected to the second block plate, and the fourth end of the second bar is pivotally connected to the second end of the first bar; and
a driver, used for driving the first bar and the second bar to move together.

8. The electronic device according to claim 1 , further comprising:
an elastic element, connecting the first block and the main body.

9. The electronic device according to claim 1 , further comprising:
a jacking plate, disposed between the first block plate and the main body and used for jacking the first block plate to project from the main body.

10. The electronic device according to claim 1 , further comprising:
a keyboard, pivotally connected to the main body;
wherein the control unit is used for controlling the keyboard to rotate until the keyboard is close to the display screen.

11. The electronic device according to claim 1 , further comprising:
an illuminating module, connected to the display screen and comprising:
an illuminating element, used for emitting light;
a first reflector, used for reflecting the light; and
a second reflector, pivotally connected to the first reflector and used for reflecting the light;

wherein the control unit is used for controlling an angle included between the first reflector and the second reflector for adjusting an illuminating scope of the light.

12. The electronic device according to claim 11 , wherein the illuminating module further comprises:
a third reflector;
wherein the illuminating element is disposed on the third reflector, and the first reflector and the second reflector are configured to be movable with respect to the third reflector.

13. A method of an electronic device being transformed into a bookshelf, comprising:
providing an electronic device, wherein the electronic device includes a main body, a display screen, a first block plate, a first image capturing unit, a second image capturing unit, an image analysis unit and a control unit;
capturing, by the first image capturing unit, a book image of a book and a first eye image of an eye;
capturing, by the second image capturing unit, a second eye image of the eye;
determining, by the image analysis unit, a relative distance between the eye and the electronic device according to the first eye image and the second eye image;
determining, by the image analysis unit, a book size of the book according to the book image;
determining, by the control unit, a suitable viewing angle according to the relative distance and the book size; and
controlling, by the control unit, the display screen to rotate, such that a viewing angle at the book viewed by the eye is substantially equal to the suitable viewing angle.

14. The method according to claim 13 , further comprising:
controlling, by the control unit, the first block plate to rotate for driving the first block plate to project from the main body.

15. The method according to claim 14 , wherein the electronic device further includes a second block plate pivotally connected to the main body, and the method further comprises:
controlling, by the control unit, the second block plate to rotate for driving the second block plate to project from the main body.

16. The method according to claim 15 , further comprising:
controlling, by the control unit, the first block plate and the second block plate to move together.

17. The method according to claim 13 , wherein the electronic device further includes an illuminating module connecting to the display screen, and the method further comprises:
controlling, by the control unit, the illuminating module to adjust an illuminating scope.

18. The method according to claim 13 , wherein the electronic device further includes a keyboard pivotally connected to the main body, and the method further comprises:
controlling, by the control unit, the keyboard to rotate until the keyboard is close to the display screen.
