在广播摄象机中,具有尺寸小、惰性低、寿命长和满意的信噪比的固态传感器,自然优于尺寸较大和寿命有限的摄象管.然而,因有图象无缺陷、低噪声的小型氧化铝视象管可供使用,将使摄象管式彩色摄象机的应用至少再延长几年.因为摄象管具有高的分辨率,在高性能摄象机和高分辨率电视(HDTV)中目前多使用摄象管.本文将对典型固态传感器和摄象管的性能加以比较.
In broadcast video cameras, solid-state sensors with small size, low inertia, long lifetime and satisfactory signal-to-noise ratio naturally outperform those with larger size and limited lifespan, however, because of image-free defects, low noise Of the small alumina tube available for use will make it possible to extend the use of the tube color camera for at least a few more years because of the high resolution of the tube and its combination with high performance cameras and high resolution television (HDTVs) are currently using camera tubes.This paper compares the performance of typical solid-state sensors and camera tubes.
