Abstract: A display screen with P screen points-of-view, P being an integer greater than or equal to 6, displays an autostereoscopic image at I image points-of-view, I being an integer greater than or equal to 2, less than or equal to P/3. The screen includes a matrix (10) of pixels arranged by rows and by columns; an optical array configured so that the P points-of-view of the screen can be perceived successively in lobes, each covering I times the average inter-pupillary distance of an observer (8), so that the screen points-of-view of each pair of points-of-view visible to the observer are separated by at least T buffer points-of-view, T being greater than or equal to 2, so that it is possible to display successively for each lobe, each of the I image points-of-view, each repeated P/I times, and that each point-of-view visible to the observer can be surrounded by at least 2 buffer points-of-view each displaying this same image point-of-view.

Abstract: The invention relates to displaying an autostereoscopic image of two viewpoints, each formed of strips of subpixels, called image strips, on an autostereoscopic display screen configured to display N viewpoints, N being greater than or equal to 3. The method includes detecting the position of a privileged observer relative to the screen; determining, for each eye of the observer, strips of the screen visible by the eye at the detected position; determining, for each eye of the observer, strips that are not visible by either of the two eyes at the position; an assignment to the subpixels, of the visible strips of the screen for each eye, of subpixels corresponding to the image strip of the corresponding eye; an assignment to the subpixels, of the non-visible strips of the screen, of subpixels corresponding to safety viewpoints constructed from subpixels of the image strips.

Abstract: A method for displaying an N-view autostereoscopic image formed of N elementary images interlaced according to a predetermined mixing scheme on a mobile display screen includes pivoting the screen; detecting a pivot angle ? of the screen; rotating the N elementary images by an inverse angle of the detected pivot angle ?, interlacing the N elementary images rotated according to the mixing scheme of the N elementary images in an initial direction, and displaying the N elementary images rotated on the display screen.

Abstract: 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 ? 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 ? relative to the direction of said columns and at a pitch that enables M?2 sub-pixels to be covered.

Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: 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.
