Advanced Camera Technologies for Broadcasting

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.

High-Resolution Image Sensor and Camera

The demand for high-reality video systems has been increasing, and to meet this demand, NHK has been researching and developing ultra-high-definition television^{1, 2} (UDTV) as a next-generation television broadcasting system. This system aims to improve the viewing experience by conveying the sense of being there and the sensation of realness through wider and higher-resolution pictures. We call this TV system Super Hi-Vision. SHV has a 7,680-pixel by 4,320-line resolution.
