According to the invention, the video data to be processed and the configuration data are transferred to the module via one and the same data bus. These modules are advantageously chained in series on a common bus which transfers to each module both the configuration data and the video data to be processed. Preferably, dead time or “blanking” periods between two picture frames transmitted on this bus are used in order to insert the configuration data.

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.

The invention relates to a method for processing a video image for a display device. In order to reduce the visibility of transition regions in the processed image, the method comprises a step of application of a third video pattern to at least one part of the image, the third video pattern resulting from the spatial interleaving of a first video pattern and at least one second video pattern according to a determined model.

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.

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.

The present invention relates to a video picture display method that aims to reduce the effects of blurring and multiple contours when the picture display frequency is doubled. According to the invention, for each source video picture, a video level dissymmetry is created between the two pictures from the source video picture after doubling the frequency in the areas in motion of the source video picture.

The invention relates to a method for video processing of at least one image of a video sequence, said video sequence comprising a plurality of image pairs, each image pair comprising a first image and a second image said first and second images being intended to form a stereoscopic image. In order to reduce display defects, the method comprises a step of generation of at least a third image by motion compensated temporal interpolation from at least two of said second images.
