MOTION COMPENSATION DEINTERLACER PROTECTION

摘要

A motion compensation deinterlacer producing a progressive scan signal from an interlaced signal is provided. This comprises a motion compensation means (18) for deriving missing lines in an interlaced field for at least one of the fields in the interlaced signal. The means (12) for driving a first confidence measure for the accuracy of the motion compensation means using known lines of the field. The means (10) for deriving a second confidence measure of the accuracy of the motion compensation using known lines of at least two other fields. It is also provided the means (16) for selecting output for display from at least the motion compensation unit (18) and one other deinterlacer (20) in dependence on the confidence measures.
