Abstract
A method for motion detection based on observing several pictures. The method may include computing a first motion score of an area in a target picture of a sequence of pictures by a comparison of the area between the target picture and a first reference picture; computing a second motion score of the area by another comparison of the area between a second reference picture and a third reference picture, where the target picture is a different picture than the second reference picture and the third reference picture; and temporal filtering the target picture with the first reference picture based on the first motion score and the second motion score. At least one of the computing of the first motion score, the computing of the second motion score, and the temporal filtering is controlled by one or more gain settings applied to the sequence of pictures in a circuit.
