Abstract

An apparatus and method for displaying data in a portable terminal to control data displayed on a projection beam screen. The apparatus includes a beam projector unit for displaying data on a beam screen, at least one camera unit for capturing the data displayed on the beam screen, and a controller for extracting a differential region between data to be displayed on the beam screen and the displayed data captured by the camera unit and displaying the data on the beam screen according to a display screen region excluding the differential region therefrom.

Claims

1. An apparatus comprising:

a memory to store data; and

a controller operatively coupled with the memory, the controller configured to;

obtain, via a camera unit operatively coupled with the controller, a first image capturing at least two objects external to the apparatus and further capturing at least one portion of a second image projected by a projector operatively coupled with the controller;

determine at least one part of the data based at least in part on the at least two objects identified in the obtained first image; and

present, via the projector, the determined at least one part of the data proximate to the at least two objects spaced apart from each other external to the apparatus,

wherein the second image is generated based on the data stored in the memory.

2. The apparatus of claim 1, wherein the at least one part comprises first data corresponding to a first object of the at least two objects and second data corresponding to a second object of the at least two objects, and

wherein determining the at least one part of the data based at least in part on the at least two objects further includes detecting that the at least one portion of the projected second image is overlapping one of the at least two objects as captured in the first image.

3. The apparatus of claim 2, wherein the controller is configured to:

present the first data associated with a first position corresponding to the first object; and

present the second data associated with a second position corresponding to the second object, respectively.

4. The apparatus of claim 2, wherein the controller is configured to:

present third data generated by associating the first data and the second data based at least in part on a determination that the first data and the second data is selected by at least one of the at least two objects.

5. The apparatus of claim 1, wherein the at least one part comprises at least one of a message, an e-mail, a schedule, a music, contact information, a social network service list, a menu, or an image.

6. The apparatus of claim 1, wherein the controller is configured to:

obtain another one or more images including the at least one part and at least one of the at least two objects; and

identify an action of the at least one in relation with the at least one part based at least in part on the other one or more images.

7. The apparatus of claim 6, wherein the controller is configured to:

present another data corresponding to the at least one part based at least in part on a determination that the action corresponds to the at least one part.

8. The apparatus of claim 6, wherein the controller is configured to:

transmit the at least one part to an electronic device external to the apparatus based at least in part on a determination that the action is to select or move the at least one part, the electronic device corresponding to one of the at least two objects.

9. The apparatus of claim 6, wherein the controller is configured to:

determine a difference between at least two images selected from the image and the other one or more images; and

identify the action based at least in part on the difference.

10. The apparatus of claim 1, wherein the at least a part comprises data received from an electronic device external to the apparatus, the electronic device being communicatively coupled with the apparatus.

11. A method comprising:

obtaining, at an electronic device, via a camera unit operatively coupled with the electronic device, A first image capturing at least two objects external to the electronic device and further capturing at least one portion of a second image projected by a projector operatively coupled with the electronic device;

determining at least one part of data based at least in part on the at least two objects identified in the obtained first image; and

presenting, via the projector, the determined data proximate to the at least two objects spaced apart from each other external to the electronic device,

wherein the second image is generated based on the data stored in a memory.

12. The method of claim 11, wherein the data comprises first data corresponding to a first object of the at least two objects and second data corresponding to a second object of the at least two objects, and

wherein determining the at least one part of the data based at least in part on the at least two objects further includes detecting that the at least one portion of the projected second image is overlapping one of the at least two objects as captured in the first image.

13. The method of claim 12, wherein the presenting comprises:

presenting the first data associated with a first position corresponding to the first object; and

presenting the second data associated with a second position corresponding to the second object, respectively.

14. The method of claim 12, comprising:

presenting third data generated by associating the first data and the second data based at least in part on a determination that the first data is selected by the first object and the second data is selected by the second object.

15. The method of claim 11, wherein the presenting comprises:

presenting, as the data, at least one of a message, an e-mail, a schedule, a music, contact information, a social network service list, a menu, or an image.

16. The method of claim 11, comprising:

obtaining another one or more images including the data and at least one of the at least two objects; and

identifying an action of the at least one in relation with the data based at least in part on the other one or more images.

17. The method of claim 16, comprising:

presenting another data corresponding to at least a part of the data based at least in part on a determination that the action is to select the at least a part of the data.

18. The method of claim 16, comprising:

transmitting another data to another electronic device corresponding to the at least one based at least in part on the determination that the action is to select or move at least a part of the data, the other data corresponding to the at least a part.

19. The method of claim 11, wherein at least a part of the data is received from another electronic device external to the electronic device.

20. An apparatus comprising:

a processor; and

a memory operatively coupled with the processor, the memory storing instructions that, when executed by the processor, cause the apparatus to;

obtain, via a camera unit operatively coupled with the processor, a first image capturing at least two objects external to the apparatus and further capturing at least one portion of a second image projected by a projector operatively coupled with the processor;

identify at least one part of data based at least in part on the at least two objects identified in the obtained first image; and

present, via the projector, the data proximate to the at least two objects spaced apart from each other external to the apparatus,

wherein the second image is generated based on the data stored in the memory.
