摘要：
A new telecine design has been equipped with a flying-spot scanner system. The new telecine model tracks and scans a frame of continuously moving film by combining a vertically oriented CCD-line sensor (which reads the instantaneous position of the moving perforation) with highly accurate deflection control equipment. The running speed of the film can be varied from still frame up to 48 frames/s, forward and reverse, by means of a single lever. Instanteneous starts and stops are also possible. The new design has many advantages when compared with ordinary telecine equipment. It is currently in use for program production at NHK (Japan Broadcasting Corp. )
