Sungkyunkwan University is a private research university with campuses in Seoul and Suwon. Originally, it was founded in 1398 by the Joseon Dynasty located in the heart of central Seoul. It was authorized as Sungkyunkwan, the foremost educational institution of Joseon, by the great code of the state administration pertaining to the royal assent.Today, the university has two campuses: the Humanities and Social science Campus in Seoul, and the Natural science Campus in Suwon. Eighteen schools and three colleges offer degrees at the bachelor's level, and twelve graduate schools confer various degrees at both the masters and doctoral levels. SKKU offers Korea’s first fully English-taught Global MBA program, which has gained tremendous international recognition. SKKU also has one of the best medical schools in South Korea, which is affiliated with the world-famous Samsung Medical Center. Samsung partnered with SKKU in the period of 1965-1977 and took up its partnership in 1996. Recent years have seen a trend of SKKU rising in university rankings, consistently placing in the top 5 nationally. Wikipedia.

According to the present invention, a lens flare generation method and apparatus are provided that may simulate lens flare effects through paraxial approximation-based linear approximation to generate a lens flare utilizing physical characteristics of a lens system while generating a lens flare at remarkably high speed as compared with the conventional art. Further, according to an embodiment of the present invention, a non-linear effect may be added to a linear pattern-based lens flare effect, generating an actual lens flare reflecting most of physical characteristics generated from the lens system. Further, use of a pre-recorded non-linear pattern allows for generation of a lens flare having a similar quality to the existing light tracking-based simulation at higher speed as compared with the conventional art without speed reduction.
