The Japanese public broadcaster NHK, in collaboration with the Shizuoka University, an 8K cmos image sensor, developed for the recording of Super Hi-Vision broadcasts of the broadcaster. The maximum frame rate is 120fps.
NHK showed last year, an 8K cmos image sensor, progressive scan-video with a frame rate of 60fps can record, but the new sensor doubles this frame rate to 120fps. The higher frame rate can be used to more fast-moving subject on the sensitive plate to capture the images in slow-motion play.
To achieve this higher frame rate, NHK, in cooperation with the university of Shizuoka a faster readout of the image sensor is generated and the a/d conversion already taking place at the pixel level. The image sensor measures 21,5 at 12,1 mm and the power consumption of the chip would be 2.5 W. Current Super Hi-Vision-videocameracamera’s we use different 4K cmos image sensors from aptina is offering, know DPReview report.
NHK, developer of the current hdtv standard, which by the broadcaster Hi-Vision is called, is expected in 2020 to begin with the first public Super Hi-Vision broadcasting in Japan. During the Olympic Games in London are already proefuitzendingen in the new format done. Super Hi-Vision, also known as ultra-hdtv, has sixteen times the resolution of current full hd.
