According to one embodiment, if the user of electronic device 400 presses the decorating key 450e shown in FIG. 6, at operation 830, processor 480 converts the decoded third image to a file And store it in the second memory 470.

According to one embodiment, the processor 480 may convert the third image into a file and delete it from the first memory 460 before storing it in the second memory 470, .

According to one embodiment, the first memory 460 stores only the URI (Uniform Resource Identifier) address for the third image, instead of storing the original data for the third image to be newly synthesized in a bit map form .

According to one embodiment, at operation 840, the processor 480, in combination with the synthesized first image 610 and the second image 620, which is converted to a file and stored in the second memory 470, The first image 610, the second image 620, and the third image can be displayed through the touch screen 440. [0050] FIG.

Using operations 810 through 840 described above, the processor 480 may synthesize one or more other newly added images.

13 is a flow diagram illustrating a method for restoring synthesized first and second images according to various embodiments of the present disclosure to original first and second images prior to synthesis.

According to one embodiment, at operation 910, the processor 480 may receive a decompression command to restore the first image 610 and the second image 620 synthesized in the operation 770 described above to their original state .

For example, the user of the electronic device 400 may press the decode release key 450k, shown in Fig. 6C, to display the original first image 610 before the first image 610 and the second image 620 are synthesized (610) and the second image (620), respectively.

According to one embodiment, at operation 920, the processor 480 may use the URI address for the original image of each of the first image 610 and the second image 620 to generate a first image 610 and a second image 620, The original image of the image 620 may be decoded into a frame form and stored and restored in the first memory 460.

According to various embodiments, the processor 480 may store the original first image 610 and the second image 610 stored in the second memory 470, for a restoration rate of the first image 610 and the second image 620, (620). For example, when the first image 610 and the second image 620 stored in the second memory 470 are deleted, the processor 480 deletes the first image 610 and the second image 610 using the URI address for the original image, ) And the second image 620, as shown in FIG.

On the other hand, if the first image 610 and the second image 620 stored as files in the second memory 470 including the file storage or the file system are deleted, the following method can be used.

According to one embodiment, the processor 480 may utilize a shared preference to restore the first image 610 and the second image 620 to their original form before being deleted.

According to one embodiment, even if the electronic device 400 is reset, the shared preference functions to restore the first image 610 and the second image 620 by storing the setting information of the electronic device 400 as it is .

According to one embodiment, the processor 480 reads the URI address of each of the first image 610 and the second image 620 using the shared preference, and reads the first image 610 through the read URI address, And the second image 620 can be extracted.

According to one embodiment, the processor 480 decodes the extracted first image 610 and the second image 620 again in the first memory 460 in the form of a bitmap, 1 image 610 and the second image 620 into a file and then store and update it in the second memory 470 again.

In addition, the following method may be used so that the first image 610 and the second image 620 stored as files in the second memory 470 including the file storage or the file system are not deleted.

According to one embodiment, the processor 480 may use the getfilesdir () application program interface (API), which the user of the electronic device 400 can not delete the file for, for example, "/ data / data / Application / Files "in the application storage space.
