Upscalers also seeks to improve local contrast and color within video.
It's also critical for upscalers to be able to tell the difference between detail and noise/Mpeg artifacts, as there's no use in upscaling the latter. 'It doesn't just look at the pixel in isolation, it looks at the pixels around it, and on each diagonal, and also it will look up the pixels across multiple frames, to give a consistency in the picture quality,' explains McCarron. 'When you're upscaling from Full HD to 4K there is a lot of guesswork, and what we're trying to do it to remove as much of the guesswork as possible.' Sony's 4K X-Reality PRO, like other picture processors, upscales at a pixel level.
Sony claims its 'lens to living room' approach is unique since it takes advantage of Sony Picture's vast experience with producing movies and TV shows, as well as its expertise manufacturing 4K video cameras used by the TV and movie industry.
