movement data storage means for storing data indicative of any movement detected picture point by picture point; and
selector means for selectively outputting stored picture information picture point by picture point from a single or both fields in dependence on the stored movement data to provide information from both fields during parts of the picture where no movement has been detected and from only a single field from parts of the picture where movement has occurred.
