Abstract

A method for adjusting the resolution of an electronic device may comprise the operations of changing resolution of a screen, which is displayed through a display functionally connected to the electronic device, when a load of a system resource is sensed, and displaying the screen through the display on the basis of an image having the changed resolution.

First claim

The invention claimed is:

1. A method for adjusting resolution of an electronic device, the method comprising:
displaying a first screen including an image through a display, the image having a first resolution;
in response to detecting a change in a system resource load, determining to change the first resolution of the image to a second resolution lower than the first resolution;
rendering a second screen including the image having the second resolution; and
displaying, through the display, the second screen by up-scaling,
wherein the determining to change the first resolution of the image to the second resolution further comprises:
displaying a screenshot based on a user input;
displaying a user interface related to a change of a resolution of the screenshot; and
receiving the user input related to the adjustment of the resolution through the user interface and changing of the resolution.

2. The method of claim 1 ,
wherein the detecting of the system resource load further comprises:
detecting at least one of memory use higher than a predetermined value and power consumption higher than a predetermined value, and

wherein the determining to change the first resolution of the image further comprises:
reducing the size of the first screen.

3. The method of claim 1 , wherein the determining to change the first resolution of the image to the second resolution further comprises:
changing the image from the first resolution to the second resolution based on at least one of the user input or predetermined information.

4. The method of claim 1 , further comprising:
generating a second image based on the second resolution; and
storing the second image in a frame buffer.

5. The method of claim 1 , wherein the determining to change the first resolution of the image to the second resolution further comprises:
displaying a user interface including an icon related to a change of a resolution when the system resource load is detected; and
changing the resolution based on the user input obtained through the user interface.

6. The method of claim 3 , wherein the determining to change the first resolution of the image to the second resolution further comprises:
displaying a notification status bar including a user interface related to the change of the resolution through the display; and
changing the resolution based on the user input obtained through the user interface.

7. The method of claim 3 , wherein the determining to change the first resolution of the image to the second resolution further comprises:
releasing the image corresponding to an application from a frame buffer when the user input for displaying the application list is received;
changing the first resolution of the image; and
displaying the second screen based on the image having the second resolution when re-launching of the application is requested.

8. An electronic device comprising:
a display;
an input/output interface;
a memory; and
at least one processor is configured to:
display a first screen including an image through a display, the image having a first resolution,
in response to detecting a change in a system resource load, determining to change the first resolution of the image to a second resolution lower than the first resolution,
render a second screen including the image having the second resolution,
display, through the display, the second screen by up-scaling,
display a screenshot on the display based on a user input requesting for a resolution change,
display a user interface for changing a resolution of the screenshot, and
receive the user input for adjusting the resolution through the user interface and change the resolution.

9. The electronic device of claim 8 , wherein the at least one processor is further configured to control to:
detect at least one of memory use higher than a predetermined value or power consumption higher than a predetermined value,
detect the system resource load,
reduce the size of the first screen, and
change the resolution.

10. The electronic device of claim 8 , wherein the at least one processor is further configured to change the image from the first resolution to the second resolution according to the user input received through the input/output interface or predetermined information stored in the memory.

11. The electronic device of claim 8 , wherein the at least one processor is further configured to:
generate a second image based on the second resolution, and
store the second image in a frame buffer.

12. The electronic device of claim 8 , wherein the at least one processor is further configured to:
display a user interface including an icon related to a change of a resolution on the display when the system resource load is detected, and
receive the user input obtained by the user interface through the input/output interface and change the resolution.

13. The electronic device of claim 10 , wherein the at least one processor is further configured to:
display a screenshot on the display based on the user input requesting for a resolution change,
display a user interface for changing a resolution of the screenshot, and
receive the user input for adjusting the resolution through the user interface and change the resolution.

14. The electronic device of claim 10 , wherein the at least one processor is further configured to:
display a notification status bar including a user interface for changing the resolution through the display, and
receive the user input for adjusting the resolution through the user interface and change the resolution.
