Abstract
A novel noise suppression method for a high-definition CCD (charge coupled device) camera, the RDS (reflection-delayed noise suppression) method, is described. By using the reflection in a delay line, it has become possible to obtain both significant noise suppression and a wide frequency bandwidth. The method is superior to conventional methods in that its frequency bandwidth is very wide and its high-speed operations are very stable. The performance of a HDTV (high-definition TV) three-CCD color camera using this method is reported
