When the plurality of cameras are driven in operation 901, the electronic device acquires a plurality of first images having a first attribute and one or more second images having a second attribute based on image information (e.g., a raw image) acquired through the first camera for a predetermined time in operation 903. For example, as illustrated in FIG. 5, the first images are a plurality of preview images acquired in the first cycle 520 through the first camera 500 for the predetermined time 550, and may have a first attribute having a relatively lower resolution than the second images. The second images are one or more captured images acquired through the first camera 500 for the predetermined time 550, and may have a second attribute having a relatively higher resolution than the first images. The time points 530 at which the second images are acquired may be determined based on one or more request signals 512 generated during the predetermined time 550.
