20080204455 | Method For Displaying an Autostereoscopic Image Having N Viewpoints - The invention relates to a method for displaying an autostereoscopic image having N viewpoints on at least a portion of a screen containing display pixels arranged in lines and columns, each display pixel containing a first, a second and a third color point aligned on the same line and each being of a different color (R.V.B.). The first display pixel of one line is constituted of color points of row 1 to 3, the second display pixel of one line is constituted of color points of row 4 to 6, the display pixel of row q of a line is constituted of color points of row (3q 2) to 3q. According to the inventive method, N is greater than 1 and the pixels of an autostereoscopic image to be displayed are displayed in such a manner that the 3 color points of each display pixel display 3 homologous color component color points of pixels of the autostereoscopic image coming from at least two pixels of the same row of at least two different viewpoints. The invention is characterized in that, for at least one group of two successive image lines comprising a first, a second and a third line, said spatial distribution of the 3 color points is offset by a step corresponding to a color point when passing from one line of the group to an adjacent line. | 08-28-2008 |
20120229896 | LENTICULAR ARRAY INTENDED FOR AN AUTOSTEREOSCOPIC SYSTEM - The invention relates to a lenticular array intended to be placed in front of a screen so as to carry out autostereoscopic viewing and comprising lenticules separated by a spacing P and extending in a longitudinal direction and which are joined together via a longitudinal principal join line, characterized in that each micro-lens is comprised of at least N′ contiguous plane faces which are joined together via a longitudinal secondary join line with N′ greater than or equal to 2, each plane face defining in cross-section perpendicular to the said longitudinal direction a straight segment, and in that the ends of the said straight segments are situated on a circular arc centred on a point O situated in the mid-plane of the said micro-lens, or else on a portion of parabola, hyperbola or ellipse with focus (F) situated in the said mid-plane (MP). | 09-13-2012 |
20130249974 | Method of Displaying an Autostereoscopic Image - Method of displaying an autostereoscopic image having N viewpoints in which at least one group of three successive screen rows having first, second, and third rows, the second row is identical to the first row, and for the third row, the spatial distribution of the three sub-pixels of the autostereoscopic image is offset relative to the second row by a pitch corresponding to one sub-pixel, the offsetting being in an elementary sequence AB, where A designates the fact that a row is identical to the preceding row, and B designates applying to a row of the image relative to the preceding row a said offset of the sub-pixels of the autostereoscopic image through a pitch corresponding to one sub-pixel. | 09-26-2013 |
20140029095 | Method of Autostereoscopic Display on a Screen Having its Largest Dimension in a Vertical Direction - A method for autostereoscopic display of an autostereoscopic image with N points of view of rank between 1 and N—in an ascending order from right to left—on a screen having pixels arranged in rows and in columns, said pixels consisting of a plurality of subpixels of different colors (R, G, B), wherein said screen is arranged with its largest dimension in the vertical direction so that the subpixels forming each pixel are arranged in said vertical direction, and each column of the screen is filled with blocks of at least three subpixels corresponding to a set of subpixels of one of the points of view of the image to be displayed, separated by blocks of one or more subpixels that are off or darkened. | 01-30-2014 |
20140078025 | Display Screen, In Particular For Autostereoscopy - A display screen (E), advantageously of the flat type, comprising a matrix of pixels (P) arranged in rows and columns perpendicular to said rows, each pixel comprising three or more sub-pixels (SP) of different colors (RGB), in alignment in the direction of said rows and presenting a shape that is elongate, the screen being characterized in that each said sub-pixel presents a main dimension forming a non-zero angle α relative to the direction of said columns. The screen may advantageously be fitted with an angle selection array for autostereoscopic display having main axes forming an angle α relative to the direction of said columns and at a pitch that enables M≧2 sub-pixels to be covered. | 03-20-2014 |

20090201824 | ESTIMATING ENDPOINT PERFORMANCE IN UNIFIED COMMUNICATION SYSTEMS - Performance of endpoints, client devices and servers within a communication system, is determined by collecting call quality data from each endpoint by a quality monitoring server/application. Call quality data includes predefined metrics based on network and end device characteristics during each call. Calls include voice, video, and data exchanges. Collected metric values are then aggregated according to a formula for consistency and scaled based on factors such as traffic volume. Resulting performance values are used to order the endpoints such that those with degraded quality and prioritized based on factors like traffic volume can be attended to first. | 08-13-2009 |
20090237240 | DETERMINING QUALITY MONITORING ALERTS IN UNIFIED COMMUNICATION SYSTEMS - Performance of endpoints, client devices and servers within a communication system, is monitored by collecting call quality data from each endpoint. The collected metric data is retrieved periodically from a database, categorized based on endpoint location and metric type, and compared to predefined thresholds for different endpoint types, metric categories, and call configurations. If an alert condition is met indicating a problem with quality of experience in the system, an alert is issued to an administrator. | 09-24-2009 |
