Method and apparatus for adjusting an image and control guides displayed on a display

A non-transitory computer-readable medium having recorded thereon a program, which when executed by a computer causes the computer to execute a method for providing a graphical user interface on a touch screen of an electronic device, the method comprising:

• displaying a preview image on the touch screen of the electronic device, wherein the preview image is an image that is currently being provided on the touch screen of the electronic device for photographing an image;
• based on a detecting a hovering over the touch screen of the electronic device, displaying a plurality of GUI items over the preview image being displayed on the touch screen, wherein one GUI item of the plurality of GUI items is for adjusting an attribute of the preview image;
• detecting a drag input corresponding to a selection of the one GUI item;
• determining a drag characteristic value of the drag input;
• and
• adjusting a visual characteristic of the one GUI item over the preview image being displayed on the touch screen and displaying the preview image having the adjusted attribute and the one GUI item having the adjusted visual characteristic on the touch screen while the drag input is detected,
• wherein the drag characteristic value of the drag input comprises at least one of a distance, a velocity, and a direction of the drag input,
• wherein the plurality of GUI items correspond to a plurality of functions for adjusting attributes of the preview image being displayed,
• wherein the visual characteristic of the one GUI item comprises a size of the one GUI item, and
• wherein the adjusting comprises adjusting the visual characteristic of all of the plurality of GUI items.

A display device comprising:

• a touch screen configured to display a preview image and a plurality of GUI items;
• a memory configured to store visual characteristics of the plurality of GUI items;
• and
• a processor configured to control the touch screen to display the preview image, the preview image is an image that is currently being provided on the touch screen of the display device for photographing an image, based on a detecting a hovering over the touch screen of the display device to display the plurality of GUI items over the preview image being displayed on the touch screen, wherein one GUI item of the plurality of GUI items is for adjusting an attribute for a preview image, detect a drag input corresponding to the one GUI item and determine a drag characteristic value of the drag input to adjust a visual characteristic of the one GUI item over the preview image being displayed on the touch screen and display the preview image having the adjusted attribute and the one GUI item having the adjusted visual characteristic on the touch screen while the drag input is detected,
• wherein the drag characteristic value of the drag input comprises at least one of a distance, a velocity, and a direction of the drag input,
• wherein the plurality of GUI items correspond to a plurality of functions for adjusting attributes of the preview image being displayed,
• wherein the visual characteristic of the one GUI item comprises a size of the one GUI item, and
• wherein the processor is further configured to adjust the visual characteristic of the one GUI item by adjusting the visual characteristic of all of the plurality of GUI items.
