Patent ID: 8351510

Claim:
A noise reducer for generating a noise reduced frame in a video sequence, the video sequence including a target frame and at least one reference frame, the noise reducer comprising: a motion estimation engine configured to generate a predictor for a target data segment of the target frame from the at least one reference frame, the predictor representing a data segment of the at least one reference frame that best matches the target data segment; and an image processor coupled to the motion estimation engine and comprising: a directional interpolation module configured to generate a first pixel of a first data segment by performing directional interpolation on an interlaced field of the target frame; a recursive motion compensation deinterlacing module configured to generate a second pixel of a second data segment by performing motion compensation on the interlaced field of the target frame using at least the predictor, a location of the second pixel in the second data segment corresponding to a location of the first pixel in the first data segment; and a blender configured to generate a third pixel in an output data segment in the target frame by at least blending the first pixel and the second pixel.
