Abstract

A mobile terminal including a transparent display module, a camera arranged in correspondence to a rear surface of the transparent display module, and configured to capture an image of a subject through the transparent display module, and a controller configured to detect interference image information included in the captured image of the subject and to compensate the captured image of the subject based or the detected interference.

Claims

1. A mobile terminal, comprising:

a transparent display module;

a camera arranged in correspondence to a rear surface of the transparent display module, and configured to capture an image of a subject through the transparent display module; and

a controller configured to detect interference image information included in the captured image of the subject and to compensate the captured image of the subject based on the detected interference.

2. The mobile terminal of claim 1, further comprising:

a memory configured to store compensation data used by the controller to compensate the captured image of the subject.

3. The mobile terminal of claim 2, wherein the compensation data includes at least one of color information (R, G, B), luminance information, brightness information, gamma control information and contrast information.

4. The mobile terminal of claim 2, wherein the memory is further configured to further store a compensation function including a mathematical algorithm used by the controller to compensate the captured image of the subject.

5. The mobile terminal of claim 1, wherein when the controller detects interference image information included in the captured image of the subject has a value less than a reference value, the controller is further configured to compensate the captured image of the subject based on one of a preset compensation data or a compensation function.

6. The mobile terminal of claim 1, wherein when the controller detects interference image information included in the captured image of the subject has a value more than a reference value, the controller is further configured to increase a transparency of the transparent display module.

7. The mobile terminal of claim 6, wherein the controller is further configured to increase the transparency of the transparent display module by changing a size, a shape or a color of information output on the transparent display module.

8. The mobile terminal of claim 6, wherein the controller is further configured to divide the transparent display module into a plurality of display regions, and to control the transparency of a display region corresponding to a location of the camera.

9. The mobile terminal of claim 8, wherein the controller is further configured to insert a specific image or a specific text along with the captured image captured of the subject at a position corresponding to the location of the camera.

10. The mobile terminal of claim 8, wherein the controller is further configured to control a transparency of a display region having an area corresponding to a size of the camera.

11. The mobile terminal of claim 1, where the transparent display module comprises an organic light emitting diode (TOLED) module.

12. A method of controlling a mobile terminal, the method comprising:

capture an image of a subject through a transparent display module via a camera arranged in correspondence to a rear surface of the transparent display module;

detecting interference image information included in the captured image of the subject; and

compensating the captured image of the subject based on the detected interference.

13. The method of claim 12, further comprising:

storing compensation data used by the controller to compensate the captured image of the subject in a memory of the mobile terminal.

14. The method of claim 13, wherein the compensation data includes at least one of color information (R, G, B), luminance information, brightness information, gamma control information and contrast information.

15. The method of claim 13, further comprising:

storing a compensation function including a mathematical algorithm used by the controller to compensate the captured image of the subject in the memory of the mobile terminal.

16. The method of claim 12, wherein when the detecting step detects interference image information included in the captured image of the subject has a value less than a reference value, the compensating step compensates the captured image of the subject based on one of a preset compensation data or a compensation function.

17. The method of claim 12, wherein when the detecting step detects interference image information included in the captured image of the subject has a value more than a reference value, the compensating step increases a transparency of the transparent display module.

18. The method of claim 17, wherein the compensating step increases the transparency of the transparent display module by changing a size, a shape or a color of information output on the transparent display module.

19. The method of claim 17, further comprising:

dividing the transparent display module into a plurality of display regions; and

controlling the transparency of a display region corresponding to a location of the camera.

20. The method of claim 19, wherein the controlling step inserts a specific image or a specific text along with the captured image captured of the subject at a position corresponding to the location of the camera.

21. The method of claim 19, wherein the controlling step controls a transparency of a display region having an area corresponding to a size of the camera.

22. The method of claim 12, where the transparent display module comprises an organic light emitting diode (TOLED) module.
