Abstract
The invention relates to a device for display an autostereoscopic image on a video screen (20) having a cylindrical lens array (10) disposed in front of it.
The video screen (20) has pixels made up of p color points (RGB) placed horizontally side by side, the number of viewpoints for the autostereoscopic image is different from p×n (where n is a non-zero integer), and the lens-- array (10) has a pitch equal to the product of the pitch of the color points (R, G, B) multiplied by the number of viewpoints, e.g. four.

8. A device for displaying an autostereoscopic image made up of image pixels having p color points, comprising:
-
a video screen having an array of screen pixels disposed in columns and rows, each screen pixel including p color points arranged along the pixel row, where p is an integer greater than 1, wherein the p color points of each image pixel of each viewpoint are spread between p different screen pixels belonging to p different columns, and a cylindrical lens disposed in front of said video screen and through which the screen pixels may be viewed, wherein the lens array has lenses at a pitch covering more than p color points in the pixel row, and such that an observer sees said spread p color points of each image pixel belonging to each viewpoint in p successive lenses of the lens array. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
