Abstract
A CCD image sensor is operated in an asynchronous mode to enable it to capture short lived events, or to freeze rapid motion. The image is acquired during an integration period which is triggered by a strobe pulse, and the resulting charge is held in a storage section of the CCD sensor until a regularly occuring field read-out period, during which the charge is read-out to constitute a video signal.
