Abstract

The disclosure provides for a display system for a vehicle comprising at least one image sensor, an image processor, and a display apparatus. The image sensor is configured to capture image data. The image processor is in communication with the image sensor and configured to generate augmented image data from the image data. The augmented image data is configured counteract a farsightedness of an occupant of the vehicle. The display apparatus is in communication with the image processor and configured to communicate the augmented image data independently to each of a right eye and a left eye of the occupant.

Claims

1. A vehicle display device comprising:

at least one image sensor configured to capture image data;

a tracking sensor configured to capture tracking data indicating a position of an occupant;

an image processor in communication with the image sensor and the tracking sensor, the image processor configured to generate augmented image data from the image data, wherein the augmented image data is configured to counteract a farsightedness of an occupant of the vehicle; and

a display apparatus in connection with the vehicle and in communication with the image processor, the display apparatus comprising a pixel array aligned with an optic array, wherein the display apparatus is configured to selectively activate pixels of the pixel array based on the position of the occupant communicating the augmented image data independently to each of a right eye and a left eye of the occupant via the optic array.

2. The display system according to claim 1, wherein the augmented image data is configured to counteract a visual correction of at least one corrective lens worn by the occupant.

3. The display system according to claim 2, wherein the visual correction corresponds to a specific prescription of the corrective lens.

4. The display system according to claim 2, wherein the at least one corrective lens comprises a first corrective lens and a second corrective lens, and wherein the augmented image data comprises right image data configured to correct for a first prescription of the first lens and left image data configured to correct for a second prescription of the second lens.

5. The display system according to claim 4, wherein the display apparatus comprises the pixel array and a lenticular lens.

6. The display system according to claim 5, wherein the image processor manipulates the image data by pairing light field rays of the pixels of the pixel array with retinal positions of the occupant.

7. The display system according to claim 5, wherein the right image data and the left image data are communicated to the occupant by selectively activating pixels of the pixel array aligned through the lenticular lens with the right eye and the left eye of the occupant respectively.

8. The display system according to claim 7, wherein the display apparatus is configured to direct the right image data to the right eye and the left image data to the left eye based on the position identified by the tracking sensor.

9. The display system according to claim 1, wherein the display apparatus corresponds to an autostereoscopic display.

10. The display system according to claim 1, wherein the display apparatus corresponds to a rearview display apparatus.

11. A display system for a vehicle comprising:

at least one image sensor configured to capture image data;

an image processor in communication with the image sensor and configured to generate augmented image data from the image data, wherein the augmented image data is configured to counteract a farsightedness of an occupant of the vehicle;

a tracking sensor configured to capture tracking data indicating a position of an occupant;

a display apparatus in connection with the vehicle and in communication with the image processor, the display apparatus comprising a pixel array aligned with an optic device, wherein the display apparatus is configured to selectively activate pixels of the pixel array aligned with the position of the occupant via the optic device communicating the augmented image data to the occupant.

12. The display system according to claim 11, wherein the augmented image data is processed by the image processor providing a perception of a magnification.

13. The display system according to claim 11, wherein the augmented image data is configured to counteract a farsightedness of an operator of the vehicle.

14. The display system according to claim 13, wherein the farsightedness comprises a specific prescription and wherein the augmented image data is manipulated by the processor correcting for the farsightedness.

15. The display system according to claim 14, wherein the image data is converted by the farsightedness of the operator thereby reverting the augmented image data to appear in focus to the operator.

16. The display system according to claim 11, wherein the optic device comprises an optic array configured to communicate the augmented image data as a right image data to the right eye and a left image data to the left eye.

17. The display system according to claim 16, wherein the optic array comprises a lenticular lens configured to project the right image data in a first direction and the left image data in a second direction.

18. A vehicle display device comprising:

at least one image sensor configured to capture image data;

a tracking sensor configured to capture tracking data indicating a position of an occupant;

an image processor in communication with the image sensor and the tracking sensor, the image processor configured to generate augmented image data from the image data, wherein the augmented image data is configured to counteract a farsightedness of an occupant of the vehicle; and

a display apparatus in communication with the image processor, the display apparatus comprising a pixel array and a lenticular lens configured to communicate the augmented image data independently to a right eye of the occupant as right image data and a left eye of the occupant as left image data, wherein the display is configured to selectively activate pixels of the pixel array aligned through the lenticular lens with the right eye and the left eye of the occupant respectively based on the position of the occupant.

19. The display system according to claim 18, wherein the augmented image data is configured to counteract a visual correction of a corrective lens of the occupant comprising a specific prescription.

20. The display system according to claim 18, wherein the image processor manipulates the image data by pairing light field rays of the pixels of the pixel array with retinal positions of the occupant, wherein the retinal positions are identified by the tracking sensor.
