Abstract
The present invention is situated within the frame or video processing domain and more particularly in the domain of video interpolation. It relates to a device for generating an interpolated frame from source frames temporarily surrounding it. This device comprises motion estimation means, motion compensated interpolation means, linear interpolation means, means for mixing the frame produced by the motion compensated interpolation means with the frame produced by the linear interpolation means. According to the invention, the mixing coefficients assigned to these two frames depend on the displaced frame difference and/or the frame difference between the source frames surrounding this interpolated frame and/or estimated motion vectors.
