Picture manipulation in video systems
First Claim
1. A video system for manipulating picture information in the form of a plurality of picture points comprising adaptive processing means for receiving a number of picture points from more than one field to provide a synthesised picture point from information on a number of existing picture points adjacent said synthesised picture point and from more than one field;
- andselector means for determining the portions of information used from the picture points from each field in dependence on picture movement therebetween.

Abstract
A video system and method for manipulating picture information in the form of a number of picture points. The information is manipulated by sequentially synthesizing a picture point from information on a number of existing picture points adjacent the synthesized picture point from at least one field. The portions of the picture points used from current and previous fields may be varied in dependence on picture movement detected between fields.
