Abstract :
A high-performance high-definition television camera is described. This camera, which employs a recently developed 1-in HARP pickup tube, provides high-quality pictures and provides 32 times maximum sensitivity compared with an HDTV camera using Saticon tubes. This camera´s amplitude response is more than 40% at 800 TV lines. Some unique techniques are developed to correct misregistration precisely and provide fine focusing
