    • The invention concerns a device and a method for generating on a defined display screen of determined size a 3D image including a left view( 1) and a right view (2) from an incoming video signal to be viewed at a distance by a viewer. The device comprises: -Means for measuring the distance (D) between the viewer and the display; -means 7 for determining a disparity threshold value in relation with the determined size of the display screen 5 and the measured distance 6 to achieve a 2D and 3D compatibility level; -means 4 for editing a disparity map corresponding to the values of disparity between the left and the right views; -means 8 for analyzing with an histogram the disparity values of the disparity map in comparison to the determined threshold value; -and means 9 for replacing one of the left or right view by a view interpolation so that the disparity level of the histogram is below the determined threshold value, if the disparity level of the histogram is above the determined disparity threshold value.
    • 本发明涉及一种用于在定义的显示屏幕上生成确定尺寸的装置和方法,该三维图像包括从观看者一段距离观看的输入视频信号的左视图(1)和右视图(2)。 该装置包括: - 用于测量观看者和显示器之间的距离(D)的平均值; - 用于确定与所确定的显示屏幕5的尺寸和测量距离6相关的视差阈值以实现2D和3D兼容性水平的装置7; - 用于编辑与左视图和右视图之间的视差值相对应的视差图; - 用于与直方图分析视差图的视差值与确定的阈值相比的方法8; 并且如果直方图的视差水平高于所确定的视差阈值,则装置9用于通过视图插值来替换左视图或右视图中的一个,使得直方图的视差水平低于确定的阈值。

    • The invention relates to a method for combating the copying of source pictures by means of a camera while they are being displayed, for example using a camcorder in a movie theatre. To this end, it is known, in classical projection systems, to modulate by a carrier wave the brightness of some pixels of the pictures. The frequency of the carrier wave is usually constant and generally half the refresh frequency. The main problem with such systems is that once a pirate has figured out what the modulation frequency is, he can configure his camcorder shutter to filter out this frequency and bypass the anti-camcorder method. According to the invention, the frequency of the carrier is changed at least once throughout the displaying of the sequence pictures or the movie, to defeat all camcorders standards (PAL/NTSC) and shutter configurations.
    • 本发明涉及一种用于在例如使用电影院中的摄像机的情况下,通过照相机对源图像进行复制的方法。 为此,在经典投影系统中,通过载波调制图像的某些像素的亮度是已知的。 载波的频率通常是恒定的,通常是刷新频率的一半。 这种系统的主要问题是,一旦盗版者了解了调制频率,他就可以配置摄像机快门来滤除这个频率,并绕过反摄像机的方法。 根据本发明,在整个序列图像或电影的显示期间,载波的频率至少改变一次,以抵消所有摄像机标准(PAL / NTSC)和快门配置。

    • The invention relates to the insertion of graphic items as subtitles in a 3D video. During the displaying, if an object of the 3D video is deeper than the graphic item, i.e. positioned behind this graphic item, the human perception will be fine. At the contrary, if the subtitles is inserted in a zone that should be partially masked by an 3D object of the image, this object being placed in front of the subtitle 3D this object, the viewer' cue is very bad. In this case, a video processing is applied to the graphic item, to help the human brain putting in accordance the 3D stereoscopic information and the interposition psychological depth cue. According to the invention, the portions of the objects of the video that are located before the graphic items, i.e. with a smaller depth, are made transparent in order to be able to display the entire graphic items. The invention relates also the terminal implementing the method of displaying.
    • 本发明涉及将图形项目作为字幕插入到3D视频中。 在显示期间,如果3D视频的对象比图形项目更深,即位于该图形项目后面,人的感知将是正常的。 相反,如果字幕被插入到应该被图像的3D对象部分掩盖的区域中,则该对象被放置在该字幕3D的该对象之前,观众的提示非常糟糕。 在这种情况下,视频处理被应用于图形项目,以帮助人脑根据3D立体信息和插入心理深度提示。 根据本发明,为了能够显示整个图形项目,将位于图形项目之前,即具有较小深度的视频的对象的部分变得透明。 本发明还涉及实现显示方法的终端。
