Crosstalk compensation in autostereoscopic displays using binocular summation

A system comprising:

• an autostereoscopic display;
• and
• at least one processor configured to:
• obtain information indicative of a relative location of a first eye and of a second eye of at least one user with respect to an image plane of the autostereoscopic display;
• generate or retrieve a first image and a second image to be directed toward the first eye and the second eye, respectively, based on the relative location of the first eye and of the second eye with respect to the image plane;
• for a given first segment of the first image presenting at least a part of a virtual object, determine an amount of crosstalk toward the first eye, based on at least the second image;
• determine a given second segment of the second image that also presents at least said part of the virtual object;
• adjust intensity values of pixels in the given second segment of the second image, based on the amount of crosstalk determined for the given first segment of the first image;
• generate an autostereoscopic image using the first image and the second image;
• and
• display the autostereoscopic image via the autostereoscopic display;
• wherein a first display region and a second display region of the autostereoscopic display are employed to emit light corresponding to the given first segment of the first image toward the first eye and to emit light corresponding to the given second segment of the second image toward the second eye, respectively,
• wherein the intensity values of the pixels in the given second segment of the second image are adjusted such that a binocular sum of:
• (i) a luminance of the light emitted from the first segment toward the first eye,
• (ii) a luminance of the light emitted from the second segment toward the second eye, and
• (iii) a luminance of the crosstalk toward the first eye,
• lies within a predefined threshold range of a target binocular luminance corresponding to said part of the virtual object:
• wherein the binocular sum (Lbinocular) is calculated using an expression:
• L
• binocular
• =
• L
• first
• 2
• +

• second
• ,
• wherein:
• Lfirst denotes a sum of (i) the luminance of the light emitted from the first segment toward the first eye and (iii) the luminance of the crosstalk toward the first eye, and
• Lsecond denotes (ii) the luminance of the light emitted from the second segment toward the second eye.
