Abstract:
The invention relates to a method for displaying a settings menu. In order to optimize the graphical representation of setting carried out by a spectator, the method comprises steps for: - displaying said settings menu comprising a three-dimensional graphical element (20) of which one of the dimensions extends according to a depth direction (z), - displaying, on said graphical element, of at least one setting (203, 204, 205) representative of at least one item of depth information.
Abstract:
The present principles relate to the optimization of distribution of audiovisual content destined for display devices of different types, such as multi-view autostereoscopic 3D displays, single view 3D displays, and 2D displays. A peer-to-peer network is used for smart distribution of so-called monoscopic views of content, so that each of the heterogeneous set of display devices can be quickly served with the content views that it needs from display devices in its neighborhood.
Abstract:
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.
Abstract:
A method to display images using four or more different primaries having different spectral distributions wherein, in the LMS color space, at least two of these primaries have the same L coordinates and the same M coordinates; thanks to the invention, different metamers, when being legally displayed, will be not only perceptually indistinguishable to a viewer with normal color vision but also indistinguishable by most of the viewers with non-normal color vision.
Abstract:
To generate a full-color left view, a the cyan(left) component of the anaglyph is added with its red component after being laterally shifted to the left, and, symmetrically, to generate a full-color right view, the red(right) component of the anaglyph is added with its cyan component after being laterally shifted to the right. According to the invention, the shift to the left of the red(right) component is obtained by adding the "details" of the cyan(left) component to a blurred red(right) component, and vice-versa. The "details" of the cyan(left) component is preferably calculated by subtracting a blurred cyan(left) component from the cyan(left) component itself.
Abstract:
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.
Abstract:
A method and an apparatus capable of increasing the video depths depending on the video content of each line in order to provide a maximum of color gradation for each given scene shall be proposed. For this purpose there is disclosed an apparatus for driving a display device (16) including input means (11) for receiving a digital value as video level for each pixel or cell of a line of the display device (16), reference signalling means (19) for providing at least one reference driving signal and driving means (15) for generating a driving signal on the basis of the digital value and the at least one reference driving signal. The apparatus further includes adjusting means (18) for adjusting the at least one reference driving signal in dependence of the digital values of at least a part of the line.
Abstract:
To generate a rising or falling edge simultaneously on the electrodes Ys and Ysa of a plasma display cell, the invention provides for the use of the power recovery circuit (2) of the control device in order to apply, to one of the electrodes Yas and Y, the rising edge applied to the other of the electrodes by a dedicated circuit (3).
Abstract:
A method for presenting a content on a display device (100) includes modifying the content by applying a geometric transformation to the content so that an area of the content on the display device is presented to a viewer with higher density of information than that in the rest of the content (S18).
Abstract:
In one embodiment, it is proposed a method for displaying a 3D content on a multi-view display device, said multi-view display device being able to display k-views, with k an integer greater or equal to two, said method being implemented on said multi-view display device. Such method is remarkable in that it comprises: - obtaining a user's input being a depth level and/or a viewpoint; - modifying said user's input in function of at least one configuration parameter, said modifying defining a group of images, said images from said group being spatially successive images of a scene at a same time; and - displaying k-views on said multi-view display device, said k-views being obtained from a process taking into accounts elements from said group of images.
