초록

FHD(Full High Definition Television)의 시대를 지나 UHD(Ultra High Definition Television) 시대를 맞이하였다. 두 TV에서 화소(Pixel)수의 차이에 따라 발생하는 문제에 대하여 이야기하고 이를 개선할 수 있는 방법을 도입하고자 한다. 이 방법은 WENO(Weighted Essential Non-Oscillation)으로 주어진 영상(Image)에 적합한 보간법을 시행하는 방법이다. 이를 통하여 영상의 왜곡현상을 줄이고 보다 나은 화질을 보장할 수 있다. 따라서 예전에 만들어진 영상물을 UHD TV로 시청하려고 할 때 WENO 방법론을 활용하면 화소수에 따른 화질의 저하 없이 UHD TV의 고화질을 누릴 수 있다.

It has passed the era of Full High Definition Television (FHD) and ended the era of Ultra High Definition Television (UHD). We will talk about the problems caused by the difference in the number of pixels in the TVs and introduce a method to improve them. This method is a method of performing an interpolation method suitable for a given image with Weighted Essential Non-Oscillation (WENO). Thus, it is possible to reduce the distortion of the image and to ensure a better image quality. Therefore, if we use the WENO methodology, when we watch old video material on UHD TV, we can enjoy high definition of UHD TV without changing the number of pixels.
