CLAIMS:

1 . A head-up display apparatus comprising:

an image source configured to generate a composite image comprising a first image and a second image;

an image splitter configured to separate the first image and the second image from the composite image;

a first imaging assembly arranged to project the first image to a first eyebox to produce a first virtual image;

a second imaging assembly arranged to project the second image to a second eyebox to produce a second virtual image; and

wherein the first eyebox is located at a position different to the position of the second eyebox.

2. A head-up display apparatus as claimed in claim 1 , wherein the first and second imaging assemblies are arranged to crop the composite image to form said first and second virtual images.

3. A head-up display apparatus as claimed in claim 1 or claim 2, wherein the image source is configured to generate the composite image from a plurality of pixels;

the first and second images being formed by the same number of pixels in the composite image; or

the first and second images being formed by different numbers of pixels in the composite image.

4. A head-up display apparatus as claimed in any preceding claim, wherein the image splitter is configured to output the first image to the first imaging assembly, and the second image to the second imaging assembly.

5. A head-up display apparatus as claimed in claim 4, wherein the image splitter comprises an optical switch for controlling the output of said first and second images to the respective first and second imaging assemblies.

6. A head-up display apparatus as claimed in claim 4, wherein the image splitter comprises a directional image source configured to control the output of said first and second images to the respective first and second imaging assemblies.

7. A head-up display apparatus as claimed in any one of the preceding claims, wherein:

the first imaging assembly comprises a first imaging mirror arranged to reflect the first image to the first eyebox; and/or

the second imaging assembly comprises a second imaging mirror arranged to reflect the second image to the second eyebox.

8. A head-up display apparatus as claimed in claim 7, wherein the first imaging mirror and/or the second imaging mirror comprises any one of: a spherical surface, an aspherical surface, or a free-form surface.

9. A head-up display apparatus as claimed in claim 7 or claim 8, wherein the first imaging assembly comprises a first light guide disposed between the image source and the first imaging mirror; and/or the second imaging assembly comprises a second light guide disposed between the image source and the second imaging mirror.

10. A head-up display apparatus as claimed in claim 9, wherein the first light guide comprises one or more fold mirrors; and/or the second light guide comprises one or more fold mirrors.

1 1 . A head-up display apparatus as claimed in any one of the preceding claims, wherein the first imaging assembly is arranged to project the first image onto a first optical combiner and the second imaging assembly is arranged to project the second image onto a second optical combiner.

12. A vehicle comprising a head-up display apparatus as claimed in any one of the preceding claims.

13. A vehicle as claimed in claim 12 comprising a windscreen, the image source being disposed in a dashboard;

wherein the first imaging assembly comprises a first fold mirror disposed above the dashboard for reflecting the first image to a first imaging mirror, and/or the second imaging assembly comprises a second fold mirror disposed above the dashboard for reflecting the second image to a second imaging mirror.

14. A vehicle as claimed in claim 13 wherein the first fold mirror and/or the second fold mirror are disposed behind a rear-view mirror.

15. A vehicle as claimed in any one of claims 12, 13 or 14 comprising first and second combiners, the first and second imaging assemblies being arranged to project the first and second images onto the first and second combiners respectively.

16. A vehicle as claimed in any one of claims 12 to 15, wherein the first imaging assembly is arranged to produce a first virtual image for viewing by a driver of the vehicle, and the second imaging assembly is arranged to produce a second virtual image for viewing by a passenger of the vehicle.

17. A head-up display apparatus substantially as herein described with reference to the accompanying figures.

18. A vehicle substantially as herein described with reference to the accompanying figures.
