Abstract

Disclosed are a method and an apparatus for defining an overlay region for an application in a user interface control region on a screen of a display in a mobile device. The application queries a platform about an overlay region desired to be generated based on a basic resolution set in the application. The platform calculates an approximate region satisfying an overlay region condition for the queried overlay region and informs the application of the approximate region. Thereafter, the application generates an overlay region corresponding to the approximate region, and the platform displays the generated overlay region on the screen.

Claims

1. A method of defining an overlay region for an application in a user interface control region on a screen of a display in a mobile device, the method comprising:

querying, by the application, a platform of the mobile device about an overlay region desired to be generated based on a basic resolution set in the application; and

generating, when the application receives an approximate region satisfying an overlay region condition preset for the queried overlay region from the platform, an overlay region corresponding to the approximate region.

2. The method as claimed in claim 1, wherein the overlay region condition includes a condition restricted by a module for processing an image of the overlay region.

3. The method as claimed in claim 2, wherein the overlay regions and the approximate region are defined by an X axis coordinate and a Y axis coordinate indicating a reference position within the user interface control region and a width and a height of a corresponding region, respectively.

4. The method as claimed in claim 3, wherein the overlay region condition includes at least one of a condition limiting a width and a height of an overlay region after scaling performed according to a physical resolution of the mobile device and a condition limiting a reference position of the overlay region.

5. A method of defining an overlay region for an application in a user interface control region on a screen of a display in a mobile device, the method comprising:

calculating, when a platform of the mobile device is queried about an overlay region desired to be generated based on a basic resolution set in the application from the application, an approximate region satisfying an overlay region condition for the queried overlay region and informing the application of the approximate region; and

displaying, by the platform, when an overlay region corresponding to the approximate region is generated by the application, the generated overlay region on the screen of the display.

6. The method as claimed in claim 5, wherein the overlay region condition includes a condition limited by a module for processing an image of the overlay region.

7. The method as claimed in claim 6, wherein the overlay regions and the approximate region are defined by an X axis coordinate and a Y axis coordinate indicating a reference position within the user interface control region and a width and a height of a corresponding region, respectively.

8. The method as claimed in claim 7, wherein the overlay region condition includes at least one of a condition limiting a width and a height of an overlay region after scaling performed according to a physical resolution of the mobile device and a condition limiting a reference position of the overlay region.

9. A method of defining an overlay region in a user interface control region on a screen of a display in a mobile device by an application, the method comprising:

querying, by the application, a platform of the mobile device about an overlay region desired to be generated based on a basic resolution set in the application;

calculating, by the platform, an approximate region satisfying an overlay region condition for the queried overlay region and informing the application of the approximate region;

generating, by the application, an overlay region corresponding to the approximate region; and

displaying, by the platform, the generated overlay region on the screen.

10. The method as claimed in claim 9, wherein the overlay region condition includes a condition limited by a module for processing an image of the overlay region.

11. The method as claimed in claim 10, wherein the overlay regions and the approximate region are defined by an X axis coordinate and a Y axis coordinate indicating a reference position within the user interface control region and a width and a height of a corresponding region, respectively.

12. The method as claimed in claim 11, wherein the overlay region condition includes at least one of a condition limiting a width and a height of an overlay region after scaling performed according to a physical resolution of the mobile device and a condition limiting a reference position of the overlay region.

13. An apparatus for defining an overlay region for an application in a user interface control region on a screen of a display in a mobile device, the apparatus comprising:

a controller for executing the application and a platform of the mobile device,

wherein the controller controls such that the application generates an overlay region corresponding to an approximate region calculated by the platform to satisfy a overlay region condition, and the platform displays the overlay region on the screen.

14. The apparatus as claimed in claim 13, wherein the controller controls such that the application queries the platform about an overlay region desired to be generated based on a basic resolution set in the application, and the platform calculates the approximate region satisfying the overlay region condition for the queried overlay region and informs the application of the approximate region.

15. The apparatus as claimed in claim 14, wherein the overlay region condition includes a condition limited by a module for processing an image of the overlay region.

16. The apparatus as claimed in claim 15, wherein the overlay regions and the approximate region are defined by an X axis coordinate and a Y axis coordinate indicating a reference position within the user interface control region and a width and a height of a corresponding region, respectively.

17. The apparatus as claimed in claim 16, wherein the overlay region condition includes at least one of a condition limiting a width and a height of an overlay region after scaling performed according to a physical resolution of the mobile device, and a condition limiting a reference position of the overlay region.
