Definitions
- the present invention relates to an autostereoscopic display device based on lenticular. It also aims at an autostereoscopic visualization method implemented in this device, as well as an associated autostereoscopic image synthesis method.
- the field of the invention is more particularly that of three-dimensional color display screens, intended for example for the dissemination of advertising messages or information to the public.
- An autostereoscopic display screen generally comprises:
- a two-dimensional electronic LCD screen or plasma screen broadcasting a previously coded content, and a 2D-3D conversion screen, disposed at a short distance from the two-dimensional screen and operating in transmission, this screen being able to be of the parallax barrier type or the lenticular type.
- Parallax barriers are simple to implement, inexpensive to manufacture, but are an obstacle to too many photons, especially when wants to encode many angles of view.
- the transmission of a mask of an autostereoscopic screen may be less than 10%. This results in problems of photon flux and brightness of the screen.
- the problem is then to find an appropriate way of coding the P views on the 2D electronic screen to standardize the horizontal and vertical loss of resolution, while maintaining the color coding RGB (Red Green Blue) or RGB (Red Green Blue) .
- RGB Red Green Blue
- RGB Red Green Blue
- the document WOO010332 thus discloses a horizontal coding on a line.
- the color coding is also performed horizontally on a line, with a different color per successive 3D pixel (lenticule).
- the lenticules are vertical, but the loss of resolution is only on the horizontal axis.
- the image for each shot is very dissymmetrical. For example, if we consider a 2D screen of dimensions in pixels 1200x768 and if we code 8 images, the resolution for each view is then 150x768, which represents a significant loss in resolution on the overall image.
- the colors coding a 3D pixel are very far apart, with 2 times the pitch of the lenticule to code the three colors. We get a color fusion that is not very good on the retina, if we want a lot of angles.
- the views are coded globally horizontally, but also vertically on 3 lines of screen pixels at least.
- the coding surface of the color is at least equal to once the size of the lenticule (in horizontal) by 3 screen pixels (in vertical).
- the loss in resolution is homogeneous in horizontal and vertical.
- it can not be suitable. satisfactorily for plasma screens in which the cells are very close, even almost joined, which would lead to a significant mixture of images of different views between they.

- the image emitted by the display screen is constituted by a set of three-dimensional pixels each constituted by the plurality P of views of an image pixel of the scene to be displayed, and in each three-dimensional pixel the different points of view of an image pixel concerned are coded horizontally while the three colors associated with each point of view of said image pixel concerned are coded in three rows along a coding axis substantially parallel to the lenticular axis.

- each three-dimensional pixel is coded, for each point of view among the plurality P of viewpoints, in the form of a first cell of a first color, d a second cell of a second color and a third cell of a third color, said first, second and third cells being respectively arranged on three consecutive rows and three consecutive color columns along a diagonal substantially parallel to the axis of the lenses, the P successive points of view associated with the same image pixel being arranged consecutively along the horizontal axis with a cyclic shift of said first, second and third colors.
- the lenticular array is advantageously arranged so that each lens of the lenticular array substantially covers on a row of the matrix screen a number of cells equal to the number P of points of view.
- the pitch of the lenticular array is preferably chosen to be substantially equal to the product of the horizontal width of the plurality P of points of view of the same image pixel and the cosine of the angle of inclination a.
- the angle of inclination a. is then advantageously chosen such that tan a is substantially equal to the ratio of the width of a color cell to the height of said color cell.

- the image emitted by the display screen is constituted by a set of three-dimensional pixels each constituted by the plurality P of views of an image pixel of the scene to be displayed, and in each three-dimensional pixel the different points of view of an image pixel concerned are coded horizontally while the three colors associated with each point of view of said image pixel concerned are coded in three rows along a coding axis substantially parallel to the lenticular axis.

- FIG 1 is a synoptic view of an autostereoscopic display device according to the invention
- FIG. 2 illustrates the internal structure of a coded image processed by the autostereoscopic display device according to the invention
- FIG. 3 illustrating the main steps of the image synthesis method according to the invention.
- the autostereoscopic display device 1 comprises a plasma screen 2 connected to an electronic module 3 for generating coded images, and a lenticular filter 4 in the form of a network of cylindrical lenses. parallel and inclined at an angle ce relative to the vertical axis of the plasma screen, this lenticular filter 4 being disposed in front of the plasma screen at a distance substantially equal to the focal length Fl of the lenses, which in a concrete example of embodiment is 20 mm, while each color cell of the display screen has a width of 286 microns.
- the autostereoscopic display device 1 is intended to provide a display of advertising or information messages at a sufficiently large distance D from the screen, for example at a distance greater than 4.5 m, so that each eye OG, OD of a viewer receives distinct optical Im, In images provided by the lenticular network 4 and that by stereoscopic effect this viewer perceives a three-dimensional image.
- the focal length of the cylindrical lenses depends on the optimal distance desired. It is necessary, at this optimal distance, that two successive images - coded by two successive color cells - are separated from the average distance Dy between two eyes, for example 65 mm.
- the focal length f of the lenses can be determined according to the width CCh of a color cell and the optimal distance Dopt, by the formula:
- the plasma screen consists, with reference to FIG. 2, of a matrix of elementary cells, comprising V rows of pixels - in FIG. 2, L1-L6 - and H pixel columns C1-C6 - in FIG. -C6-, each column of pixels comprising three columns of RVB color cells.
- Each cell has, as a nonlimiting example, a height CCv and a width CCh.
- the columns of the visualization matrix are successively columns of cells of Red, Green and Blue color. In the case described, the number P of viewpoints taken into account in the stereoscopic coding of the image is equal to 9.
- each cell has a height CCv equal to 808 microns and a width CCh 286 ⁇ m.
- the visualization matrix MC is coded so as to constitute a set of three-dimensional pixels or 3D pixels, each 3D pixel consisting of 9 coding pixels each corresponding to a point of view of a coded image pixel and arranged horizontally within the pixel. 3D.
- each 3D pixel can be considered, with reference to FIG. 1, as an assembly of P (for example 9) coding pixels Pk of the same coded image point in the visualization matrix under P points of view.
- a 3D pixel 12 which corresponds to a coordinate image point (1,2), consists of 9 coding pixels (li, 2 ), (2i, 2 ), (3i / 2 ) ( 4i, 2 ), (5i, 2 ), (6i, 2 ) / (7i, 2 ), (81,2), (9i, 2 ) each associated with a point of view for the image pixel [ 1,2] concerned.
- the coding pixel (li, a) is itself composed of the following three cells:
- the 9 coding pixels of the 3D pixel 12 are horizontally nested and substantially covered by the cylindrical lenticule Li which has an angle of inclination a and a width 2 which are determined to ensure this coverage of 3D pixels.
- the angle of inclination a is such that tan is equal to the ratio of the height CCv of a cell to its width CCh.
- the width of the lenticule depends in particular on the optimum distance desired. Indeed, when the spectator is at the optimal distance (finite distance), the distance separating two points of the two-dimensional screen seen simultaneously by a spectator's eye through two successive cylindrical lenses is not exactly equal to the horizontal distance separating the axes of the cylindrical lenses. The proportionality relation is equal to Dopt / (Dopt + f).
- the width Z of each lenticular element can thus be determined from the following formula:
- Each coding pixel is thus composed of three color cells each belonging to a row of pixels and a color column consecutive within the 3D pixel, so that this coding pixel has a color coding axis substantially parallel to the axis of the lenticular array. Furthermore, the color sequence of each coding pixel is shifted cyclically to each consecutive coding pixel within a 3D pixel.
- FIG. 3 will now be an example of an implementation of a method for synthesizing autostereoscopic images according to the invention, these images being intended to feed an autostereoscopic display device according to the invention.
- a prior phase (I) for obtaining digital images is considered according to a plurality of points of view, for example 9 in number, suitably chosen to provide a stereoscopic effect.
- These digital images can be either synthesized or collected from remote sites or image banks, or still acquired by shooting.
- Each of these digital images Ii, I2, • •, IK, • • -, Ip is constituted, for each point of view, of a matrix of image pixels, each of these image pixels Pi (i, j), .. , P ⁇ (i, j) containing three color information RV B.
- a second phase (II) of the synthesis method consists in constructing a display matrix MC by elaborating, for each image point (i, j), a 3D pixel , referenced P3D (i, j) in FIG.
- the display arrays MC each corresponding to an image of a coded sequence SC are then stored in a US image storage unit intended to be requested in response to a request from a control processor of an autostereoscopic display device 1 according to the invention.
- the invention is not limited to the examples that have just been described and many adjustments can be made to these examples without departing from the scope of the invention.
- the invention is not limited to the single case of a plasma screen but can be implemented with other types of matrix structure screen, contiguous or spaced cells.
