Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
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.
Claim 2
Dependent Claim
120 words
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.
Claim 3
Dependent Claim
67 words
A time registration circuit arrangement as claimed in claim 1, wherein said signal generator comprises a signal shaper comprising a pair of input means for receiving a standard field synchronisation signal and a signal having pulses which occur at double the line frequency respectively, and an output means for supplying said field synchronisation-deflection signal with pulses which occur at an integral multiple of said standard field frequency.
Claim 4
Dependent Claim
59 words
A time registration circuit arrangement as claimed in claim 2, wherein said signal shaper comprises an output means for supplying a switching signal which occurs at the field frequency, which switching signal comprises switching pulses having a pulse duration within which pulses occur which are present in said field synchronistion-deflection signal and which occur outside standard field blanking times.
Claim 5
Dependent Claim
52 words
A time registration circuit arrangement as claimed in claim 3, further comprising a time signal generator, and a switching stage having a switching input coupled to said switching signal output and a pair of input means adapted to be coupled to the television camera and coupled to said time signal generator respectively.
Claim 6
Dependent Claim
50 words
A time registration circuit arrangement as claimed in claim 2, wherein said signal shaper comprises setting-resetting stages, and divider stages each having input means for releasing and blocking coupled to said setting-resetting stages respectively, and input means for receiving the signal having pulses which occur at double the line frequency.
