Method and device for obtaining image, and recording medium thereof

A method of obtaining an image in a device, the method comprising:

• changing at least one of parameters about light comprising a preset pattern and projected onto an object and light reflected and fed back by the object to obtain a plurality of depth images of the object;
• merging pieces of depth information respectively obtained from the obtained plurality of depth images with each other, when a motion of the device is less than a threshold;
• and
• obtaining a 3D image of the object, based on the merged pieces of depth information and a color image of the object.

A non-transitory storage medium comprising a program, for obtaining an image on an electronic device, the program comprising program code that, when executed by at least one processor of the electronic device, causes the electronic device to:

• change at least one of parameters about light comprising a preset pattern and projected onto an object and light reflected and fed back by the object to obtain a plurality of depth images of the object;
• merge pieces of depth information respectively obtained from the obtained plurality of depth images with each other, when a motion of the electronic device is less than a threshold;
• and
• obtain a 3D image of the object, based on the merged pieces of depth information and a color image of the object.
