摘要： The invention relates to layered depth data. In multi-view images, there is a large amount of redundancy between images. Layered Depth Video format is a well-known formatting solution for formatting multi-view images which reduces the amount of redundant information between images. In LDV, a reference central image is selected and information brought by other images of the multi- view images that are mainly regions occluded in the central image are provided. However, LDV format contains a single horizontal occlusion layer, and thus fails rendering viewpoints that uncover multiple layers dis-occlusions. The invention uses light filed content which offers disparities in every directions and enables a change in viewpoint in a plurality of directions distinct from the viewing direction of the considered image enabling to render viewpoints that may uncover multiple layer dis-occlusions which may occurs with complex scenes viewed with wide inter-axial distance.

本发明涉及分层深度数据。在多视图图像中，图像之间存在大量的冗余。分层深度视频格式是用于格式化多视图图像的众所周知的格式解决方案，可减少图像之间的冗余信息量。在LDV中，选择参考中心图像，并提供多视图图像的其他图像所带来的信息，这些图像主要是中央图像中被遮挡的区域。但是，LDV格式包含单个水平遮挡层，因此无法呈现揭示多个图层遮挡的视点。本发明使用光场内容，其在各个方向上提供视差，并且使得在与所考虑的图像的观看方向不同的多个方向上改变视点，使得能够呈现可以揭示可能出现在复杂场景中的多层分布的视点以宽广的轴间距离观看。

摘要： The invention consists in a method for generation of 3D image signals. A graphic object is inserted in said image at a determined depth. A frame of a determined thickness surrounds the object to be inserted. A transition zone is defined by the frame around the inserted graphic object. The depths of image elements of the transition zone vary progressively from the external edge to the internal edge of the frame of the graphic object to be inserted. The present invention also relates to a device for generation of said display signals.

摘要： 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 and a right view from an incoming video signal to be viewed at a distance by a viewer. The device comprises: Means for measuring the distance between the viewer and the display; means for determining a disparity threshold value in relation with the determined size of the display screen and the measured distance to achieve a 2D and 3D compatibility level; means for editing a disparity map corresponding to the values of disparity between the left and the right views; means for analyzing with an histogram the disparity values of the disparity map in comparison to the determined threshold value; and means 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.

摘要： L'invention concerne un procédé de traitement d'images source destiné à lutter contre leur copie par un caméscope ou une caméra lors de leur affichage, par exemple dans une salle de cinéma. La séquence d'images source représente une scène. Selon l'invention, le procédé comprend les étapes suivantes :
- détection (20) , dans ladite scène, d'au moins une zone correspondant à un objet de la scène,
- sélection (21) de la totalité des pixels de ladite au moins une zone dans au moins une image source de la séquence ; et
- traitement (22) de ladite au moins une image source pour modifier la couleur des pixels sélectionnés ou la composition spectrale de la lumière émise par les pixels sélectionnés de sorte que la couleur perçue des pixels sélectionnés soit inchangée dans l'image source traitée par rapport à l'image source.
摘要翻译：该方法涉及检测与场景中的对象相对应的区域，以及选择包括在源图像序列的区域中的像素。处理源图像以便改变所选择的像素的颜色或由所选择的像素发射的光的光谱组成，使得所处理的源图像中所选择的像素的感知颜色相对于原始源图像不变。还包括用于显示源图像序列的方法的独立权利要求。

摘要： 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.
