According to various embodiments, an electronic device includes at least one camera and at least one processor. The processor is configured to acquire, through the at least one camera, a first video of which the maximum luminance is a first luminance, check a first tone mapping function for converting the first video into a second video of which the maximum luminance is a second luminance that is lower than the first luminance, and check a second tone mapping function for converting the first video into a third video of which the maximum luminance is a third luminance that is lower than the second luminance. The processor is configured to relate, to the first video, first metadata based on the first tone mapping function and second metadata based on the second tone mapping function and store same.
