국문 초록

In 2014, UHD transmission was launched for the first time in the world through several pay channels in Korea. Then on May 31st, 2017, three terrestrial broadcasters started using UHD broadcasting in the metropolitan area with a frequency of 700 MHz. However, there still remains a problem of standardization and hardware problem of conversion of expensive equipment and a shortage of UHD contents due to lack of production resources. The selection of color space and lens in the content production stage is a factor that determines the quality of UHD HDR image. Therefore in this paper, we analyzed differences of the four types of lens: ARRI (Ultra Prime, 85mm), SONY Prime (85mm), FUJINON (ZK3.5x85, 85-300mm) and CANON (CN7x17KSA, 17-120mm) in BT.709 and BT.2020 color space in order to produce UHD HDR contents. For this purpose, 35 participants were subjected to a corresponding sample T test. The results show that there is a difference in color depending on the type of lens in the BT.709 gamut and a little difference in color in the BT.2020 gamut depending on the lens type. It will be applied to the uniform quality control of contents through color correction in BT.2020.
