Referring to FIG. 13, the electronic device detects one or more third images corresponding to one or more candidate images (or at least one final candidate image) among one or more third images acquired through the second camera for a predetermined time in operation 1301. The one or more third images corresponding to the one or more candidate images (or the at least one final candidate image) may include one or more third images acquired at a capture time point, which is the same as or similar to the capture time point (e.g., a time stamp) of the candidate images (or the final candidate image). The third images having a capture point similar to that of the candidate images (or the final candidate image) may include one or more third images, which differ from the candidate images within a predetermined range in terms of difference in time information. The candidate images (or the final candidate image) may include one or more second images determined to be captured at an optimal photographing time among the one or more second images.
In operation 1303, the electronic device sets a display region for the candidate images (or the final candidate image) based on the third images corresponding to the candidate images (or the final candidate image). The display region may include one or more regions in the candidate images (or the final candidate image) for extraction or cropping in order to adjust the image magnification of the candidate images (or the final candidate image).
