Frame rate up-conversion based on mixed interpolation

Frame rate up-conversion is used to reduce large area flicker. In this paper, frame average interpolation and interpolation based on motion compensation are analyzed and the results are compared. Based on the differences that the interpolated pixel projects on the two connective frame, a simple and effective interpolation algorithm which is sum of the result of frame average and motion compensation is presented. Experiment results show that this mixed interpolation can maintain the advantages of motion compensation interpolation and at the same time use the motion vectors more safety, that makes it more appreciable in the still areas than motion compensation interpolation.
