When receiving a user input for acquiring an image content, the processor 301 may acquire a plurality of first images having a first attribute and one or more second images having a second attribute different from the first attribute based on image information (e.g., raw data) acquired through the camera 303 for a predetermined time. The first images may be a plurality of preview images acquired in a first cycle for a predetermined time, and may have a first attribute having a relatively lower resolution compared to the second images. The second images may be one or more captured images acquired for a predetermined time, and may have a second attribute having a relatively higher resolution compared to the first images.
When the camera 303 supports an auto-focus (AF) function, the second images may be acquired based on focus information on an external object (e.g., a subject) for a predetermined time. For example, the second images may be acquired when the camera 303 is focused. When the camera 303 does not support the AF function, the second images may be acquired for a predetermined time in a second cycle different from the first cycle. For example, the second cycle may be relatively longer than the first cycle. Because the second images and the first images are generated based on image information acquired through the camera 303 for a predetermined time, the second images may include the same time information (e.g., time stamp) as at least some of the first images.
