Description

[Technical Field] Various embodiments of the disclosure relate to a method of providing a guide map, and an electronic device supporting the method. [Background Art] An electronic device such as a smart phone may enlarge or reduce a preview image displayed on a display. For example, the electronic device may enlarge or reduce the preview image displayed on the display, based on one of a plurality of magnifications. [Disclosure of Invention] [Technical Problem] However, when the electronic device shakes (e.g., when a hand tremor is detected) in a situation where the preview image is enlarged by at least a designated magnification (e.g., 20.0x magnification), a phenomenon may occur in which an area other than an area intended to be enlarged is displayed on the display. For example, when the electronic device shakes slightly (e.g., 3mm) in a state where the preview image is enlarged by 100 magnification, another area outside the area originally intended to be enlarged may be disposed on the display. Various embodiments of the disclosure may provide a method of providing a guide map and an electronic device supporting the method, so that the guide map is provided to display which part of an enlarged preview image displayed on a display corresponds to an image obtained through a camera, when the electronic device shakes in a situation where the preview image is enlarged by at least a designated magnification. [Technical Solution] An electronic device according to an embodiment of the disclosure may include a display, a camera, and a processor. The processor may be configured to display, on the display, a first image obtained through the camera, display, in response to the first image being enlarged by one magnification in a designated first magnification range, the enlarged first image as a second image, display, in a designated area of the display, a guide map including a first guide box indicating a location of the second image and having a size which varies in response to a magnification change in the first magnification range, and when the first image or the second image is enlarged to a third image in response to the first image or the second image being enlarged by one magnification in a designated second magnification range greater than the first magnification range, change the first guide box to a second guide box having a fixed size. The second guide box may indicate a location of the third image on the guide map. An electronic device according to an embodiment of the disclosure may include a display, a sensor, a camera, and a processor. The processor may be configured to display, on the display, a first image obtained from the camera, enlarge the first image by one magnification in a first magnification range, and upon detecting shaking of the electronic device through the sensor while the first image is enlarged by one magnification in the first magnification range, display a guide map in a designated area of the display. In addition, a method of providing a guide map according to an embodiment of the disclosure may include displaying, on a display, a first image obtained from a camera of an electronic device, displaying, in response to the first image being enlarged by one magnification in a designated first magnification range, the enlarged first image as a second image, displaying, in a designated area of the display, a guide map including a first guide box indicating a location of the second image and having a size which varies in response to a magnification change in the first magnification range, and when the first image or the second image is enlarged to a third image in response to the first image or the second image being enlarged by one magnification in a designated second magnification range greater than the first magnification range, change the first guide box to a second guide box having a fixed size. The second guide box may indicate a location of the third image on the guide map. [Advantageous Effects of Invention] According to various embodiments of the disclosure, when an electronic device shakes in a situation where a preview image is enlarged by at least a designated magnification, a guide map indicating a location of the preview image enlarged and displayed on a display is provided to identify whether the preview image displayed on the display is a preview image intended to be enlarged. In addition, according to various embodiments of the disclosure, when an area of a preview image enlarged and displayed on a display is a different area outside an area originally intended to be enlarged, a graphic effect may be applied to a guide map, which indicates a location of an area currently displayed on the display and a location of the area intended to be enlarged, thereby providing a guide to display on the display the area of the preview image intended to be enlarged. In addition thereto, various effects which are directly or indirectly understood through the disclosure may be provided.
