Abstract
A T.V. picture freeze system capable of capturing a video frame comprising first and second fields. Movement is detected between fields for each picture point and data indicative of any movement is stored and is used on read out to determine whether the picture information is taken from a single field, when movement has occurred or from both fields when movement has not occurred for that portion of the picture.
