With the widespread introduction of digital terrestrial broadcasting, HD is now becoming the normal picture quality. Based on these higher expectations for beautiful visual images, 4K resolution is now attracting attention, as it offers four times the definition of HD.
The ultra-high-resolution 4K format can even convey visual details such as texture and air clarity, enabling viewers to experience a realistic picture as never before. Already being used for digital cinematography, 4K resolution is expected to have numerous other applications outside of the entertainment field, including advertising, healthcare, design/engineering, electronic catalogs, and printing.
