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 electronic device comprising:

an image projection unit for projecting at least one image stored in the devi e onto an external screen;

at least one camera unit for capturing the external screen to which the at ast one image is being projected; and

a controller configured to;

detect an obscured region of the at least one image based on a comparison of he at least one image and the captured external screen image; and

generate a second image by repositioning at least one content in the obscured region to an outside region relative to the obscured region of the at least one image, such that in the second image, obscuration of the at least one content is eliminated; and

project the generated second image onto the external screen.

2. The electronic device of claim 1,

wherein the second image is generated by repositioning contents of the at least one image based on the comparison so that no region of the at least one image is obscured.

3. The electronic device of claim 1, wherein the at least one camera unit and the image projection unit are arranged linearly, and an angle between the at least one camera unit and the image projection unit is adjustable.

4. A method for displaying data in an electronic device, the method comprising:

projecting at least one image stored in the device onto an external screen by an image projection unit;

capturing the external screen to which the at least one image is being projected by at least one camera wait;

detecting an obscured region of the at least one image based on a comparison of the at least one image and the captured external screen image; and

generating a second image by repositioning at least one content in the obscured region to an outside region relative to the obscured region of the at least one image, such that in the second image, obscuration of the at least one content is eliminated; and

projecting a the generated second image onto the external screen.

5. The method of claim 4 wherein the second image is generated by repositioning contents of the at least one image based on the comparison so that no region of the at least one image is obscured.

6. The method of claim 4, wherein at least one camera unit and the image projection unit are arranged in a line, and an angle between the at least one camera unit and the image projection unit is adjustable.
