Abstract

A computer system having a main body, a first display device connected to the main body to display a picture and at least one other display device in communication with the main body to display a picture. The computer system has a user selection part to input a selection of displaying an image displayed on the first display device on the at least one other display device until another input selection or release. A control part controls transmission of a video signal corresponding to the selected image to the at least one other display device based on the user selection part. Thus, same or different images can be displayed on a plurality of display devices according to a user selection.

Claims

1. A computer system having a main body, a first display device connected to the main body to display images, and at least one external display device connected with 1/0 ports provided in the main body to display the images, the computer system comprising:

a displayed image selector selecting one of the images displayed on the first display device, in response to a user input; and

a controller controlling transmission of a video signal corresponding to the selected image, based on an image selection signal from the displayed image selector, to the at least one external display device through the I/O ports to display the selected image on the at least one external display device.

2. The computer system according to claim 1, further comprising a memory part storing the video signal of the selected image,

wherein the controller controls displaying the video signal stored in the memory part on the at least one external display device.

3. The computer system according to claim 1, wherein the controller controls displaying the selected image on the at least one external display device until a next image selection signal is transmitted from the displayed image selector.

4. The computer system according to claim 2, wherein the controller controls displaying the selected image on the at least one external display device until a next image selection signal is transmitted from the displayed image selector.

5. The computer system according to claim 1, wherein the controller determines whether the I/O ports of the main body are connected with the at least one external display device, and controls displaying the selected image on the at least one external display device, if the I/O ports of the main body are connected with the at least one external display device.

6. The computer system according to claim 2, wherein the controller determines whether the I/O ports of the main body are connected with the at least one external display device, and controls displaying the selected image on the at least one external display device, if the I/O ports of the main body are connected with the at least one external display device.

7. The computer system according to claim 5, wherein the controller controls displaying a warning message on the first display device, if the I/O ports of the main body are not connected to the at least one external display device.

8. The computer system according to claim 6, wherein the controller controls displaying a warning message on the first display device, if the I/O ports of the main body are not connected to the at least one external display device.

9. A method of displaying on a computer system having a main body, a first display device connected to the main body to display an image, and at least one external display device connected with I/O ports provided in the main body to display an external display image, the display method comprising:

selecting the image displayed on the first display device according to a user input; and

displaying the selected image on the at least one external display device, in response to the user input image selection.

10. The display method according to claim 9, further comprising:

providing a memory part storing a video signal of the selected image,

wherein the displaying of the selected image on the at least one external display device comprises displaying the video signal stored in the memory part on the at least one external display device.

11. The display method according to claim 9, wherein the displaying of the selected image on the at least one external display device comprises displaying the selected image on the at least one external display device until a next user input image selection.

12. The display method according to claim 10, wherein the displaying of the selected image on the at least one external display device comprises displaying the selected image on the at least one external display device until a next user input image selection.

13. The display method according to claim 9, further comprising:

determining whether the I/O ports of the main body are connected with the at least one external display device; and

displaying the selected image on the at least one external display device, if determined that the I/O ports of the main body are connected with the at least one external display device.

14. The display method according to claim 10, further comprising:

determining whether the I/O ports of the main body are connected with the at least one external display device; and

displaying the selected image on the at least one external display device, if determined that the I/O ports of the main body are connected with the at least one external display device.

15. The display method according to claim 13, further comprising:

displaying a warning message on the first display device, if the I/O ports are not connected to the at least one external display device.

16. The display method according to claim 14, further comprising:

displaying a warning message on the first display device, if the I/O ports are not connected to the at least one external display device.

17. A computing device connectable with a first display device and at least one second display device, comprising:

an image processor displaying an image on the first display device; and

a programmed computer processor allowing selection of the image processor image displayed on the first display device, and displaying the selected image on the at least one second display device while the image processor displays the image or a different image on the first display device.

18. The computing device of claim 17, wherein the programmed computer processor displays a selectable graphical display of an image selection button on the image processor image for selection thereof.

19. The computing device of claim 17, wherein the programmed computer processor allows releasing the displaying of the selected image on the at least one second display device.

20. A machine readable storage storing at least one program controlling a computer with at least two or more display devices according to a process comprising:

allowing selection of an image displayed on a first display device; and

displaying the selected image on second display devices while the selected image or a different image is displayed on the first display device.

21. A method, comprising:

simultaneously displaying same or different images on a plurality of display devices connected to a computer, in response to a user input displayed image selection.

22. The method of claim 21, further comprising:

displaying an image by an image processor on a first display device;

displaying a selectable graphical display of an image selection button on the image processor image on the first display device for selection thereof by the user;

storing the image processor image on the first display device in a memory, in response to a selection of the image processor image as the user input displayed image selection via the image selection button; and

displaying the stored image processor image on second display devices independent of the displaying of the displaying by the image processor on the first display device, until a next selection of a next image processor image or a release of the displaying the stored image processor image on the second display devices.
