    摘要: The present invention relates to a method for detection of film mode or camera mode of a video sequence. This detection is carried out using histograms of video levels of frames of the video sequence. Difference histograms are calculated then compared with each other so as to generate difference parameters for each video frame of the sequence. The pattern formed by these difference parameters is then compared with predetermined patterns to deduce the mode, film or camera, of the sequence. The advantage of this method is that it requires just small memory resources for its implementation and can therefore be implanted in an FPGA circuit.

    摘要: 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.

    摘要: The invention proposes a motion compensated video interpolation that is not sensitive to the errors in the motion estimation vectors. The invention proposes a motion compensated video interpolation method in which the interpolation step varies according to the amplitude and/or a reliability index of the estimated motion vector for the considered pixel. The number of pixels to be taken into account for interpolation and the weighting factors associated with these pixels are made to vary according to the amplitude and/or reliability index of the estimated motion vector.
