摘要

Japan Broadcasting Corp. (NHK) has been researching and developing Super Hi-Vision with 33 megapixels (7680 pixels by 4320 lines of resolution) as the next-generation ultra-high-definition television (UHDTV) broadcast system. In 2011, 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 the International Telecommunications Union Recommendations Section's Recommendation BT.2020. This paper reports on 120 Hz Super Hi-Vision devices that have been developed. One is a 120 Hz Super Hi-Vision image-capture device that uses three 120 Hz, 33-megapixel complementary metal oxide semiconductor image sensors. The sensors use 12-bit analog-to-digital converters and operate at a data rate of 51.2 Gbits/sec. A 120 Hz Super Hi-Vision projector has also been developed using three 8-megapixel liquid crystal on silicon chips. These 120 Hz Super Hi-Vision devices were exhibited at NHK's open house in May 2012 and demonstrated superb picture quality with less motion blur.
