ABSTRACT
<p>NHK, the Japan Broadcasting Corporation, has developed many camera technologies for broadcasting. This article focuses on three of their latest innovations: an 8,000-pixel by 4,000-line high-resolution camera, a high-speed camera that captures images at up to 1 million frames per second, and a high-sensitivity camera that is 50 times more sensitive than conventional broadcasting charge-coupled device (CCD) cameras.</p>
INDEX TERMS
Super hi-vision; SHV; broadcasting camera; high-speed, high-gain avalanche rushing amorphous photoconductor; HARP
