Method and apparatus for integrated motion compensated noise reduction and frame rate conversion

摘要

A video processing system may receive a current raw video frame and may estimate motion between the current frame and a previous frame to determine motion vectors (mv). Based on the same mvs, motion compensated (MC) noise reduction may be performed and MC frame rate conversion (FRC) may generate a new frame. The previous frame may be noise reduced and/or a raw video frame. A MC frame may be generated based on the previous video frame and the mvs. Noise reduction may comprise blending the current raw frame with the MC frame. A blending factor may be determined based on similarity between pixels of the current video frame and MC pixels of the previous frame. The mvs may be scaled for FRC. Noise reduction may be performed in parallel and/or prior to the FRC depending on whether raw or noise reduced frames are utilized.
