Abstract

A method of controlling a mobile communication terminal, and which includes projecting display information via a projector module onto an external surface; detecting, via a sensor included in the terminal, a motion of the mobile communication terminal; calculating, via a controller, an amount of the detected motion of the mobile communication terminal; and moving, via the controller controlling the projector module, the display information projected onto the external surface based on the calculated amount of the detected motion.

Claims

1. A method of scrolling projected display information of a mobile communication terminal, the method comprising:

projecting display information via a projector module onto an external surface;

detecting, via a sensor included in the terminal, a motion of the mobile communication terminal;

calculating, via a controller, an amount of the detected motion of the mobile communication terminal; and

moving, via the controller controlling the projector module, the display information projected onto the external surface based on the calculated amount of the detected motion,

wherein the projected display information is only a portion of an entire display information and the detected motion is in one of a horizontal direction, a vertical direction and a diagonal direction,

if the detected motion is in the horizontal direction, the moving step moves the portion of projected display information in an opposite horizontal direction such that other portions of the entire display information that are horizontal to the only portion of the entire display information are projected and viewable,

if the detected motion is in the vertical direction, the moving step moves the projected display information in an opposite vertical direction such that other portions of the entire display information that are vertical to the only portion of the entire display information are projected and viewable, and

if the detected motion is in the diagonal direction, the moving step moves the projected display information in an opposite diagonal direction such that other portions of the entire display information that are diagonal to the only portion of the entire display information are projected and viewable.

2. The method of claim 1, wherein the sensor includes at least one of a camera configured to detect a position shift of the projected display information, and a motion sensor configured to detect the motion of the mobile communication terminal.

3. The method of claim 1, further comprising:

displaying a scrolling icon on a display area of the mobile communication terminal that can be selected to scroll the projected display information.

4. The method of claim 3, wherein the displaying step displays the scrolling icon based on at least one of a predetermined manipulation of a key on the terminal, a predetermined touch pattern occurring on a touch screen of the display area, and a predetermined movement of the mobile communication terminal.

5. The method of claim 3, wherein the displaying step displays the scroll icon on the display area of the mobile communication terminal as one of a transparent scroll icon and an on screen display (OSD) scroll icon.

6. The method of claim 3, wherein the displayed scroll icon includes at least one of an image position navigation function that can be selected to navigate through the projected display information, an image enlarge/reduce function that can be selected to enlarge or reduce the projected display information, an image rotation function that can be selected to rotate the projected display information, and an image direction navigation function that can be selected to change a direction of the projected display information.

7. The method of claim 1, wherein the projected display information includes map information.

8. The method of claim 1,

wherein the moving step moves the projected display information such that other portions of the entire display information are projected and viewable.

9. The method of claim 1, wherein the projected display information includes a plurality of pages of display information, and

wherein the moving step pages through each page of display information based on the detected motion.

10. A mobile communication terminal, comprising:

a projector module configured to project display information onto an external surface;

a sensor configured to detect a motion of the mobile communication terminal; and

a controller configured to calculate an amount of the detected motion of the mobile communication terminal, and to control the projector module to move the display information projected onto the external surface based on the calculated amount of the detected motion,

wherein the projected display information is only a portion of an entire display information and the detected motion is in one of a horizontal direction, a vertical direction and a diagonal direction,

if the detected motion is in the horizontal direction, the controller is further configured to control the projector module to move the projected display information in an opposite horizontal direction such that other portions of the entire display information that are horizontal to the only portion of the entire display information are projected and viewable,

if the detected motion is in the vertical direction, the controller is further configured to control the projector module to move the projected display information in an opposite vertical direction such that other portions of the entire display information that are vertical to the only portion of the entire display information are projected and viewable, and

if the detected motion is in the diagonal direction, the controller is further configured to control the projector module to move the projected display information in an opposite diagonal direction such that other portions of the entire display information that are diagonal to the only portion of the entire display information are projected and viewable.

11. The mobile communication terminal of claim 10, wherein the sensor includes at least one of a camera configured to detect a position shift of the projected display information, and a motion sensor configured to detect the motion of the mobile communication terminal.

12. The mobile communication terminal of claim 10, further comprising:

a display configured to display a scrolling icon that can be selected to scroll the projected display information.

13. The mobile communication terminal of claim 12, wherein the display is further configured to display the scrolling icon based on at least one of a predetermined manipulation of a key on the terminal, a predetermined touch pattern occurring on a touch screen of the display, and a predetermined movement of the mobile communication terminal.

14. The mobile communication terminal of claim 12, wherein the display is further configured to display the scroll icon as one of a transparent scroll icon and an on screen display (OSD) scroll icon.

15. The mobile communication terminal of claim 12, wherein the displayed scroll icon includes at least one of an image position navigation function that can be selected to navigate through the projected display information, an image enlarge/reduce function that can be selected to enlarge or reduce the projected display information, an image rotation function that can be selected to rotate the projected display information, and an image direction navigation function that can be selected to change a direction of the projected display information.

16. The mobile communication terminal of claim 10, wherein the projected display information includes map information.

17. The mobile communication terminal of claim 10,

wherein the controller is further configured to control the projector module to move the projected display information such that other portions of the entire display information are projected and viewable.

18. The mobile communication terminal of claim 10, wherein the projected display information includes a plurality of pages of display information, and

wherein the controller is further configured to control the projector module to page through each page of display information based on the detected motion.
