The Scan'o'vision principle

This was the first continuous- image electronic recording device to combine precision and practicality in the field. The beauty of its invention lies in the fact that it can record continuous images at different speeds and transfer them without distortion on to a single-speed video recorder.

The Scan'o'vision produces two recordings of the same finish: one on magnetic tape, trough the dynamic memory, and the other stored in the static image memory. In a continuous- image film camera, the clock and the pick- up speed are independent. In a continuous- image CCD camera, the clock links the two functions. Apart from the technical aspect, that is the most important difference in principle. Fusion of the chronograph and the time detector has thus been achieved.
