Abstract
An electronic device according to various embodiments may comprise: a communication module; an image sensor; a control circuit electrically connected to the image sensor, acquiring a first image and a second image in order by using the image sensor, compressing the first image according to a first compression scheme by using attribute information generated in relation to an operation of compressing an image acquired before acquisition of the first image, compressing the second image according to the first compression scheme by using first attribute information generated in relation to an operation of compressing the first image, and generating second attribute information in relation to an operation of compressing the second image, and a processor electrically connected to the control circuit and the communication module, wherein the processor is configured to: acquire, from the control circuit, the first image compressed by the first compression scheme and the second image compressed by the first compression scheme, decompress the first image compressed by the first compression scheme and the second image compressed by the first compression scheme, compress the decompressed first …
