Method of performing previewing and electronic device for implementing the same
An electronic device is configured to perform a method of previewing images photographed by a plurality of cameras. The method includes displaying a main preview image of a first one of the cameras, and displaying a sub preview image of a second one of the cameras in the main preview image; changing a property of the sub preview image in response to movement of the electronic device; and when the movement of the electronic device stops, restoring the changed property to an original property before the changing.
1. A method of previewing images photographed by a plurality of cameras, by an electronic device, the method comprising:
displaying a main preview image of a first one of the cameras, and displaying a sub preview image of a second one of the cameras in the main preview image;
changing a property of the sub preview image in response to a movement of the electronic device; and
when the movement of the electronic device stops, restoring the changed property to an original property before the changing.
2. The method of claim 1 , wherein the changing of the property of the sub preview image comprises at least one of:
changing the sub preview image to be semi-transparent; and
reducing a size of the sub preview image.
3. The method of claim 1 , wherein the changing of the property of the sub preview image comprises one of:
changing the sub preview image to be semi-transparent without a change in a display location of the sub preview image;
reducing a size of the sub preview image without the change in a display location of the sub preview image; or
terminating the displaying of the sub preview image.
4. The method of claim 1 , further comprising:
determining when the movement of the electronic device stops.
5. The method of claim 1 , wherein the electronic device is a smart phone.
6. An electronic device comprising:
a plurality of cameras;
a display unit configured to preview images photographed by the cameras;
a sensor unit configured to detect a movement of the electronic device; and
a processor configured to:
control the display unit to display, in a main preview image of a first one of the cameras, a sub preview image of a second one of the cameras;
change a property of the sub preview image in response to the movement of the electronic device; and
restore the changed property to an original property before the changing when the movement of the electronic device stops.
7. The electronic device of claim 6 , wherein to change the property of the sub preview image, the processor is configured to at least one of:
change the sub preview image to be semi-transparent; and
reduce a size of the sub preview image.
8. The electronic device of claim 6 , wherein to change the property of the sub preview image, the processor is configured to one of:
change the sub preview image to be semi-transparent without a change in a display location of the sub preview image;
reduce a size of the sub preview image without the change in a display location of the sub preview image; and
terminate the displaying of the sub preview image.
9. The electronic device of claim 6 , wherein the processor is further configured to determine when the movement of the electronic device stops.
10. The electronic device of claim 6 , wherein the electronic device is a smart phone.
