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( 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.

摘要： To capture an image, the image sensing period of this image is subdivided into a plurality of successive illumination periods, and the value which is assigned to each pixel to capture the image is the sum of the integrals of intensity of illumination of this pixel over each of said successive illumination periods. According to the invention, this sum is weighted by an apodization function in order to emulate a mechanical shutter. Temporal aliasing issues and temporal ringing artifacts of digital imaging are prevented or at least limited.

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.
摘要翻译：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。

摘要： The present invention relates to the architecture of a valve of liquid crystal elements with pixel memory for front or rear projector. The valve (1) comprises elements arranged in rows and columns, each of the elements comprising a liquid crystal controlled by drive means so as to display video information relating to at least one image. According to the invention, one seeks to reduce the size of the drive means of the liquid crystals. Accordingly, capacitors and transistors of the drive means are shared in common between several elements of the valve. The video information intended to be displayed by each of the elements of the valve is coded as a common value (VC) shared by a group of at least two adjacent elements of the valve and a specific value (VS1, VS2) before being transmitted to the valve (1).

摘要： The present invention relates to a method of displaying video images on a display device and especially on a plasma display panel. The frame for displaying a video image is divided into two subframes, both comprising approximately the same number of subscans. The subscans of the first subframe are arranged in a first order in which their weights increase and those of the second subframe in the reverse order. The second subframe is consecutive to the first subframe. Each cell of the PDP changes state at least once during the first subframe. The same applies during the second subframe.

摘要： The present invention is directed to a method and a device for dealiasing borders in a 3D interpolated view, the interpolated view comprising at least foreground pixels with foreground video information (V1 ) and background pixels with background video information (V2). The method comprises the step of detecting, in an interpolated disparity map, associated to the 3D interpolated view, an aliased border between the foreground pixels with a foreground disparity value (D1 ) and the background pixels with a background disparity value (D2), the aliased border delimiting an inner aliased contour formed by foreground pixels and an outer aliased contour formed by background pixel, the aliased border having the form of a stair line; determining a weighting/dealiasing coefficient (DC) for each pixel of the outer contour said coefficient corresponding to the part of the pixel area included in the virtual right triangle defined by the two sides of each stair line to the area of the pixel; calculating video information for each pixel of the outer contour in combining the background video information and the foreground video information in a proportion defined by the determined weighting/dealiasing coefficient (DC) and replacing video information for each pixel of the outer contour by the calculated video information.
