Abstract

Systems and methods are described for determining a tracked position associated with viewing an emitting interface of a display device, generating, using the tracked position, a first mask representing a first set of values associated with the emitting interface of the display device, generating, using the tracked position, a second mask representing a second set of values associated with the emitting interface of the display device, and generating an output image using the first mask and the second mask.

First claim

What is claimed is:

1 . A computer-implemented method comprising:
at least one processing device; and memory storing instructions that when executed cause the processing device to perform operations including:
determining a tracked position associated with viewing an emitting interface of a display device;
generating, using the tracked position, a first mask representing a first set of values associated with the emitting interface of the display device;
generating, using the tracked position, a second mask representing a second set of values associated with the emitting interface of the display device; and
generating an output image using the first mask and the second mask, the generating of the output image including:
obtaining a left image with a first set of pixels and a right image with a second set of pixels,
assigning the first set of values to the first set of pixels in the left image,
assigning the second set of values to the second set of pixels in the right image, and
interleaving the left image with the right image according to the assigned first set of values and the assigned second set of values.

2 . The method of claim 1 , wherein:
providing the output image to the display device, the output image being configured to provide the left image to a left eye of a user viewing the emitting interface of the display device while simultaneously providing the right image to a right eye of the user viewing the emitting interface of the display device.

3 . The method of claim 1 , wherein the first mask and the second mask are derived from topographical four-dimensional surfaces, the first mask and the second mask being generated by applying a non-linear mapping to fractional portions of the surfaces.

4 . The method of claim 1 , wherein:
the first mask represents a first subset of pixels for a detected head position of a user viewing the display device; the second mask represents a second subset of pixels for the detected head position of the user; and the first mask and the second mask are used to obtain, for a plurality of changeable head positions of the user, a value for each pixel associated with the display device.

5 . The method of claim 1 , wherein the first mask and the second mask are color images having red, green, and blue color components, each color component is used to determine a respective color component of the output image.

6 . The method of claim 1 , wherein the tracked position is a head position of a user and wherein the first mask and the second mask are updated based on a detected movement of the head position.

7 . The method of claim 1 , wherein the first mask and the second mask include representations for at least one color index for each pixel of the display device.

8 . The method of claim 1 , wherein the tracked position varies for each row of the display device.

9 . A system, comprising:
at least one computing device including,
a memory storing executable instructions; and
a processor configured to execute the instructions, to cause the at least one computing device to:
generate a first mask representing a first set of values associated with an emitting interface of a display device;
generate a second mask representing a second set of values associated with the emitting interface of the display device; and
obtain a left eye image with a first set of pixels;
obtain a right eye image with a second set of pixels;
assign the first set of values to the first set of pixels;
assign the second set of values to the second set of pixels; and
generate an output image, the output image being generated by weaving together the left eye image and the right eye image according to the assigned first set of values and the assigned second set of values.

10 . The system of claim 9 , wherein:
at least a portion of the first set of pixels is viewable from a first location and the first location is associated with a left eye of a user viewing the display device; and at least a portion of the second set of pixels is viewable from a second location and the second location is associated with a right eye of the user viewing the display device.

11 . The system of claim 9 , wherein the first mask and the second mask are derived from topographical four-dimensional surfaces with plotted lines representing locations of light projected through a plurality of lenticular lenses associated with the emitting interface of the display device, the first mask and the second mask being generated by applying a non-linear mapping to fractional portions of the surfaces.

12 . The system of claim 9 , wherein:
the first mask represents a first subset of pixels for a detected head position of a user viewing the display device; the second mask represents a second subset of pixels for the detected head position of the user; and the first mask and the second mask are used to obtain, for a plurality of changeable head positions of the user, a value for each pixel associated with the display device.

13 . The system of claim 9 , wherein the first mask and the second mask are color images having red, green, and blue color components, each color component is used to determine a respective color component of the output image.

14 . The system of claim 9 , wherein the first mask and the second mask include representations for at least one color index for each pixel of the display device.

15 . A display device system, comprising:
a tracking module; a display panel coupled to a lenticular lens array; at least one processing device; and a memory storing instructions that when executed cause the system to perform operations including:
determining a tracked position associated with viewing an emitting interface of a display device;
generating, using the tracked position, a first mask representing a first set of values associated with the emitting interface of the display device;
generating, using the tracked position, a second mask representing a second set of values associated with the emitting interface of the display device; and
generating an output image using the first mask and the second mask, the generating of the output image including:
obtaining a left image with a first set of pixels and a right image with a second set of pixels,
assigning the first set of values to the first set of pixels in the left image,
assigning the second set of values to the second set of pixels in the right image, and
interleaving the left image with the right image according to the assigned first set of values and the assigned second set of values.

16 . The system of claim 15 , wherein:
providing the output image to the display device, the output image being configured to provide the left image to a left eye of a user viewing the emitting interface of the display device while simultaneously providing the right image to a right eye of the user viewing the emitting interface of the display device.

17 . The system of claim 15 , wherein the first mask and the second mask are derived from topographical four-dimensional surfaces with plotted lines representing locations of light projected through a plurality of lenticular lenses associated with the emitting interface of the display device, the first mask and the second mask being generated by applying a non-linear mapping to fractional portions of the surfaces.

18 . The system of claim 15 , wherein the first mask and the second mask are color images having red, green, and blue color components, each color component is used to determine a respective color com
