The invention concerns a method and a device for inserting 3D graphic animation in a 3D image, each 3D graphic element of the graphic animation being defined in size and in depth for the insertion in a determined insertion zone of said 3D image. The method comprises the step of determining for the graphic element to be inserted a depth range with a maximum allowed depth value, replacing the out of range depth values by the maximum allowed depth value when depth values of the graphic element are out of range and compensating the depth difference between the depth values of the graphic element and the maximal allowed depth value in reducing the graphic element in size proportionally to the reduction of depth for the graphic element.

A method for processing a stereoscopic image that includes a first image and a second image that has at least one first black band. To reduce the display errors linked to black bands, the method estimating at least one first parameter representative of the at least one first black band generating a third image from the stereoscopic image by disparity compensated interpolation. The third image includes at least one second black band, with at least one second parameter representative of the at least one black band being a function of at least one first parameter. The invention also relates to a corresponding stereoscopic image processing module and a display device including the processing module.

The process is characterized in that it performs: Application relates to image interpolation.

Method for detecting saturation of a motion vector field

A method of detecting the reliability of a field of movement vectors of one image in a sequence of video images. The method includes a stage of calculating a stability parameter, Det_Stab(t), for the field. The parameter is based on a comparison (), over two successive images, of the number of occurrences of the majority vectors of the movement-vectors fields of each of these images. A field is defined as stable if the variation in the number of occurrences lies within a predefined bracket. Reliability () is decided on the basis of this stability parameter.

A device for decoding a video stream in trick mode includes a random access source of coded video pictures, a means for establishing an order for pictures to be decoded, a plurality of reconstruction buffers for storing decoded pictures, and a video decoder for decoding coded pictures. The decoding device further includes a means for monitoring the availability of the reconstruction buffers. In one embodiment, a method of the present invention performed, for example by the coding device, includes establishing an order of decoding pictures and commanding the video decoder to decode a picture upon availability of a reconstruction buffer.

A process comprises a step ( ) of creating histograms of an image representing the occurrences of the luminance values as a function of these values. A further step compares ( ) a histogram of an image T(t) with a histogram of a previous image T(t&minus; ), and is characterized in that the step of comparing ( ) consists of calculating, for an occurrence histo lum (n,t) corresponding to a luminance value n in the image T(t), the absolute differences between this occurrence and the occurrences histo_lum (n&plus;k, t&minus; ) of the previous image, where K is a natural integer and varies from &minus;K to &plus;K. The process is further characterized by choosing the minimum value Min_Diff (n, t) from among these differences, and is characterized further by in summing ( ) the minimum values for the set of luminance values of the histogram, and comparing ( ) the sum obtained with a threshold.
