1. An electronic device comprising:
a camera configured to configure a plurality of exposure values;
a sensor configured to detect an image capturing environment of the electronic device;
memory storing instructions, a first application, and a second application, and
at least one processor electrically connected with the camera and the sensor,
wherein the instructions, when being executed by the at least one processor, cause the electronic device to:
while the first application is executed:
acquire information on the image capturing environment through the sensor,
configure two or more exposure values among the plurality of exposure values based on the acquired information on the image capturing environment,
acquire frames to which the two or more configured exposure values are alternately applied,
generate an uncompressed video file based on the acquired frames, and
store the uncompressed video file, at least one index, and the information on the image capturing environment, wherein the at least one index indicates at least one index frame determined at least partially based on an exposure value from the acquired frames; and
while the second application is executed:
determine a first frame from among the at least one index frame indicated by the at least one index,
determine at least one second frame from the uncompressed video file based on the information on the image capturing environment, and
acquire a composite image by composing the first frame and the at least one second frame.
