NHK has been researching and developing SUPER Hi-VISION, with 33 megapixels (7,680-pixel by 4,320-line of resolution), as the next-generation ultra-high definition television (UHDTV) broadcast system. Last year, NHK reported that it had decided to double the frame rate of SUPER Hi-VISION video to 120 Hz to improve its motion portrayal quality. This UHDTV system has been standardized as Recommendation ITU-R BT.2020. — We report on 120-Hz SUPER Hi-VISION devices that we have developed in this paper. One is a 120-Hz SUPER Hi-VISION image-capture device that uses three 120-Hz, 33-megapixel CMOS image sensors. The sensor uses 12-bit ADCs and operates at a data rate of 51.2 Gbit/s. We have also used three 8-megapixel LCOS chips and e-shift technology to develop a 120-Hz SUPER Hi-VISION projector. These 120-Hz SUPER Hi-VISION devices were exhibited at our open house in May 2012 and demonstrated superb picture quality with less motion blur.
