Abstract
A method for temporal filtering based on motion detection on areas of different sizes is disclosed. Step (A) may compute a first motion score of a first area in a target picture by motion detection of the first area between the target picture and a reference picture. Step (B) may compute a second motion score of a second area in the target picture by motion detection of the second area between the target picture and the reference picture. The first area and the second area are generally of different sizes. Step (C) may temporal filter the target picture with the reference picture based on the first motion score and the second motion score to generate a filtered picture. At least one of the first motion score, the second motion score and the filtered picture may be based on one or more gain settings in a circuit.
