Autostereoscopic video device and system
First Claim
1. A device for displaying an autostereoscopic image on a video screen having a cylindrical lens array disposed in front of it, and comprising cylindrical lenses each having an axis parallel to a direction, and the video screen having pixels made up of p color points placed side by side perpendicularly to said direction, where p is an integer greater than 1, the number of viewpoints for the autostereoscopic image being different from p×
- n where n is a non-zero integer, and wherein the lens array has a pitch equal to the product of the color point pitch multiplied by the number of viewpoints.

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.

4. A method of processing an autostereoscopic image for the purpose of being displayed by a device having a video screen and an array of cylindrical lenses each having an axis parallel to a direction and disposed in front of the video screen, the video screen having pixels made up of p color points placed side by side perpendicularly to said direction, the autostereoscopic image being made up of a number of viewpoints which number is different from p×
- n, n being a non-zero integer, the lens arras having a pitch equal to the product of the color point pitch multiplied by the number of viewpoints, the method including a step of pixel color point permutation such that an observer sees the p color points of each pixel belonging to each viewpoint in p successive lenses of the lens array.
