Abstract
According to an embodiment, a method may include segmenting a first image into a first block and a second block, generating first compression loss data corresponding to the first block and second compression loss data corresponding to the second block, identifying a first compression property, segmenting a second image into a third block and a fourth block and compressing the second image, wherein the compressing includes compressing the third block according to the first compression property, generating third compression loss data corresponding to the third block, when a difference between the first compression loss data and the third compression loss data meets a first predetermined condition, compressing the fourth block according to the first compression property, and when the difference meets a second predetermined condition, compressing the fourth block according to a second compression property. Other various embodiments are possible as well.
