Embodiment Construction

[0036] figure 1The illustrated system includes a computer system 10 (eg, a personal computer) that includes a graphics card 12 that drives a monitor 14 to display images on a screen 16 of the monitor. A lens array 18 is disposed in front of the screen 16 , while a video camera forming part of an eye-tracking or head-tracking system 20 is mounted on the monitor 14 and communicates with the computer system 10 .

[0037] Graphics card 12 accesses two texture maps L and R stored in memory of computer system 10 . The texture map L stores image information of the left channel, ie, image information to be displayed to the left eye of a user (not shown) viewing the screen 16 through the lens array 18 . Similarly, texture map R stores image information for the right channel of the user's right eye. The head tracking system tracks any movement of the user's head and notifies these movements to the computer system, which then adjusts the information displayed on the screen 16 according...

Abstract

The present invention provides a method for the autostereoscopic representation of images on a screen, wherein image information of separate channels for a right eye (34) and a left eye (32) of a user is displayed in interleaved segments (52, 54) on the screen, and a lens array (18) is disposed for deflecting light emitted from the screen such that the image information of each channel is visible only for one eye of the user, characterised by the steps of defining a channel mask (44), as determined by the lens array (18), in a display coordinate system that has a fixed relationship to the lens array (18) subjecting the channel mask to a coordinate transformation that corresponds to a projection of the channel mask (44) from a principal plane (p) of the lens array (18) onto on object plane (o) of the screen, with a position (U) of the user as projection centre, thereby to assign to each pixel of the screen a correlation with at least one of the channels, storing, for each channel, a texture map containing the image information of that channel, performing a coordinate transformation that associates each pixel of the screen with an area in at least one of the texture maps, said transformation representing the deflection of light from the pixel by the lens array (18), and determining the contents of each pixel on the basis of its correlations with the texture maps and the contents of the associated area of these texture maps.

Description

technical field [0001] The present invention relates to a method for autostereoscopic display of images on a screen, wherein separate channels of image information for the user's right and left eyes are displayed in alternating sections on the screen, and a lens array is arranged so that from the screen The emitted light is deflected so that the image information of each channel is only visible to one eye of the user. Background technique [0002] According to the general principle of stereoscopy, the impression of spatial depth is produced by presenting the observer's two eyes with two different images showing the same scene from slightly different Reflects the parallax between the observer's left and right eyes. [0003] Conventional systems for presenting different images to the user's left and right eyes employ a headset or light blocking glasses, however these are very annoying to the user. [0004] US 6,302,541 A1 describes a method of the above-mentioned type, which...
