Abstract
A time video registration arrangement in which, with the use of a television camera, a storage device and a display device, each constructed in accordance with a television standard, time measurements can be performed at intervals smaller than the standard field period. To that end the arrangement is provided with a signal generator for supplying a field synchronization-deflection signal to the camera, which signal has a repetition period which is an integral part of the field period, while a video signal of standard field frequency is applied to the storage device.
Claims5
A time registration circuit arrangement for use with a television camera and a display device, said circuit comprising a storage device means adapted to be coupled to said camera and said display device for storing a video signal which is produced by the television camera and which represents a scene, a signal generator means adapted to be coupled to the television camera for supplying to the camera a field synchronisation-deflection signal having a repetition frequency which is essentially an integral multiple of the field frequency according to a television standard, and means adapted to be coupled to the television camera and coupled to the storge device for providing a video signal having the field frequency in accordance with the standard.
