Patent ID: 8331458

Claim:
A method for composite noise filtering, comprising the steps of: (A) detecting if a current block in a current field of a composite video is part of a still picture using a circuit; (B) detecting if said current block is part of a telecine sequence; (C) generating a pair of motion compensated blocks from two repeated fields in said telecine sequence where said current block is part of said telecine sequence, said repeated fields having a same parity as each other; (D) determining one of a plurality of modes to filter said current block where said current block is part of said telecine sequence; and (E) generating a filtered block version of said current block in response to said pair of motion compensated blocks according to said one mode, wherein said modes comprise (i) a first mode where said current field is a later of said repeated fields, (ii) a second mode where said current field in an earlier of said repeated fields and (iii) a third mode where said current field is different than both of said repeated fields.
