Pixel-intensity modulation technique for frame-sequential stereo-3D displays

A processing unit configured to perform operations comprising:

• arrange alternating first-perspective and second-perspective images for frame-sequential stereoscopic display into a sequence comprising a first string of multiple first-perspective images and a second string of multiple second-perspective images for display;
• alter a pixel intensity of a first boundary image in the first string, wherein the first boundary image is next to a boundary between the first string and the second string, such that the pixel intensity of the first boundary image is closer to a pixel intensity of a second boundary image in the second string, wherein the second boundary image is next to the boundary between the first string and the second string;
• and
• adjust a pixel intensity of a second image in the first string such that an average pixel intensity of images in the first string remains substantially the same.

A system, comprising:

• a processing unit configured to prepare images for frame-sequential stereoscopic display, wherein the preparation of the images for frame-sequential stereoscopic display includes
• arranging alternating first-perspective and second-perspective images for the frame-sequential stereoscopic display into a sequence comprising a first string of multiple first-perspective images and a second string of multiple second-perspective images for display,
• altering a pixel intensity of a first boundary image in the first string, wherein the first boundary image is next to a boundary between the first string and the second string, such that the pixel intensity of the first boundary image is closer to a pixel intensity of a second boundary image in the second string, wherein the second boundary image is next to the boundary between the first string and the second string, and
• adjusting a pixel intensity of a second image in the first string such that an average pixel intensity of images in the first string remains substantially the same;
• and
• a display configured to display the images prepared by the processing unit.

A computer-program product comprising a non-transitory computer-readable storage medium containing instructions that, if executed on a computing device, define a processing unit for preparing images for frame-sequential stereoscopic display, wherein the processing unit is configured to:

• arrange alternating first-perspective and second-perspective images for the frame-sequential stereoscopic display into a sequence comprising a first string of multiple first-perspective images and a second string of multiple second-perspective images for display;
• alter a pixel intensity of a first boundary image in the first string, wherein the first boundary image is next to a boundary between the first string and the second string, such that the pixel intensity of the first boundary image is closer to a pixel intensity of a second boundary image in the second string, wherein the second boundary image is next to the boundary between the first string and the second string;
• and
• adjust a pixel intensity of a second image in the first string such that an average pixel intensity of images in the first string remains substantially the same.
