Temporal filter with criteria setting maximum amount of temporal blend

Abstract:

An apparatus includes a processor circuit and a correction circuit. The processor circuit may be configured to receive a sequence of pictures. The correction circuit may be configured to (i) generate a motion score based upon target samples from a target picture and reference samples from one or more reference pictures of the sequence of pictures, (ii) generate a first weight value based upon the motion score and a first weight limit value, and (iii) generate a plurality of blended picture samples by combining the target samples and the reference samples based upon the first weight value.
