Abstract

A display control device includes a position specifying unit, an image specifying unit and a controller. The position specifying unit specifies a position of a second apparatus on a display screen of a first apparatus. The image specifying unit specifies one of an image displayed on a display screen of the second apparatus and an image that is designated from among two or more images displayed on the display screen of the second apparatus. The controller controls such that a certain image according to the image specified by the image specifying unit is displayed at a certain position on the display screen of the first apparatus according to the position of the second apparatus specified by the position specifying unit.

Claims

1. A display control device for a first display screen of a first display apparatus and a second display screen of a second display apparatus, comprising:

a position specifying unit that specifies a position of the second display apparatus placed on the first display screen of the first display apparatus to determine the position of the certain image displayed on the first display screen;

an image specifying unit that specifies an image stored on the second display apparatus and displayed on the second display screen of the second display apparatus; and

a controller that controls such that a certain image according to the image specified by the image specifying unit is displayed at a certain position on the first display screen of the first display apparatus, wherein

the second display screen of the second display apparatus includes a shared area and a personal area, and

if the image specified by the image specifying unit and displayed in the personal area moves to the shared area, the certain image according to the moved image is displayed at the certain position on the first display screen while displaying the moved image in the shared area.

2. The display control device according to claim 1, wherein

the image specifying unit specifies the image displayed on the second display screen of the second display apparatus, and

the certain image is the same image as the image specified by the image specifying unit.

3. The display control device according to claim 1, wherein

the image specifying unit specifies the image that is designated from among two or more images displayed on the second display screen of the second display apparatus, and

the certain image is different from the image specified by the image specifying unit.

4. The display control device according to claim 1, wherein

the controller controls such that the certain image is displayed in a state where an upper side of the certain image is oriented to a direction along which the second display screen of the second display apparatus is usually viewed.

5. The display control device according to claim 1, wherein

the certain image is an image having a predetermined first relationship with the image specified by the image specifying unit, and

the certain position is a position having a second relationship in arrangement, according to the predetermined first relationship, with the position of the second display apparatus specified by the position specifying unit.

6. The display control device according to claim 1, wherein

the certain image includes two images preceding and following the image specified by the image specifying unit in a predetermined sequence relationship, and

the certain position includes two positions that are symmetrical with the position of the second display apparatus specified by the position specifying unit as a center.

7. The display control device according to claim 1, further comprising:

an orientation specifying unit that specifies an orientation of the second display apparatus on the first display screen of the first display apparatus, wherein

the controller controls such that the certain image is displayed in accordance with the orientation of the second display apparatus specified by the orientation specifying unit.

8. The display control device according to claim 1, wherein the position specifying unit specifies the position of the second display apparatus based on information that is acquired when the first display apparatus acquires information retained by the second display apparatus.

9. The display control device according to claim 1, wherein the position specifying unit specifies the position of the second display apparatus based on information that is acquired when the second display apparatus acquires information retained by the first display apparatus.

10. The display control device according to claim 1, further comprising:

a recognition unit that recognizes change in the image displayed on the second display screen of the second display apparatus, wherein

the controller controls such that the certain image, according to an image displayed on the second display screen of the second display apparatus after the change recognized by the recognition unit is made, is displayed at the certain position on the first display screen of the first display apparatus.

11. The display control device according to claim 1, wherein the position specifying unit determines the position and an identification of the second display apparatus by capturing a code image.

12. The display control device according to claim 1, wherein

the second display screen of the second display apparatus placed on the first display apparatus includes a shared area and a personal area, and

if an image displayed in the personal area moves to the shared area, the image displayed in the personal area is displayed on the first display screen of the first display apparatus as the certain image and is displayed in the shared area.

13. The display control device according to claim 1, wherein

the certain image is displayed in a state where an upper side of the certain image is oriented in a direction parallel to an upper edge of the second display screen of the second display apparatus.

14. The display control device according to claim 1, wherein

the certain image displayed on the first display screen and the moved image displayed on the second display screen have the same content.

15. The display control device according to claim 1, wherein:

the position specifying unit specifies the position and an identification of the second display apparatus placed on the first display screen of the first display apparatus by capturing a tangible code image formed on a bottom surface of the second display apparatus.
