a signalization signal is determined for signalizing the pixel values of the pixels by means of the optical display device.

2. The method according to claim 1 , wherein the navigation information comprises a driving instruction for a vehicle user.

3. The method according to claim 1 , wherein as a function of specified route data and/or specified environment data, a three-dimensional model is determined for a specified environment of the vehicle, and

the pixel values for the at least one portion of the pixels of the digital image and/or of the graphic element are determined as a function of the three-dimensional model.

4. The method according to claim 2 , wherein as a function of specified route data and/or specified environment data, a three-dimensional model is determined for a specified environment of the vehicle, and

the pixel values for the at least one portion of the pixels of the digital image and/or of the graphic element are determined as a function of the three-dimensional model.

5. The method according to claim 3 , wherein the optical display device comprises a head-up display with a specified display field, and

the pixel values of the graphic element are determined such as a function of the dataset and the three-dimensional model and are displayed on the display field that a viewer of the display field perceives the graphic element from a specified viewing position with a direct reference to the real environment of the vehicle.

6. The method according to claim 4 , wherein the optical display device comprises a head-up display with a specified display field, and

the pixel values of the graphic element are determined such as a function of the dataset and the three-dimensional model and are displayed on the display field that a viewer of the display field perceives the graphic element from a specified viewing position with a direct reference to the real environment of the vehicle.

7. A data determination unit configured to:

determine a dataset as a function of a specified navigation information, the dataset having a metadata structure which is suitable for textually characterizing the navigation information, wherein the dataset consists of only non-graphic text data; and

send the dataset by way of a specified communication interface.

8. An image determination unit, which can be coupled with respect to signals with an optical display device of the vehicle, configured to:

receive a specified dataset which is transmitted by way of a specified communication interface, wherein the dataset consists of only non-graphic text data,

as a function of the received dataset, determine pixel values for at least a portion of pixels of a digital image and/or of a graphic element, and

determine a signalization signal for signalizing the pixel values of the pixels by means of the optical display device.

9. The image determination device according to claim 8 , further configured to:

determine, as a function of specified route data and/or specified environment data, a three-dimensional model for a specified environment of the vehicle, and

determine the pixel values for the at least one portion of the pixels of the digital image and/or of the graphic element as a function of the three-dimensional model.

10. The image determination unit according to claim 9 , wherein the optical display device comprises a head-up display with a specified display field, and wherein the image determination unit is configured to:

determine the pixel values of the graphic element as a function of the dataset and the three-dimensional model and causing them to be displayed on the specified display field of the head-up display such that a viewer of the display field will perceive the graphic element from a specified viewing position with direct reference to the real environment of the vehicle.

11. A display system for a vehicle comprising:

a data determination unit configured to determine a dataset as a function of a specified navigation information, the dataset having a metadata structure which is suitable for textually characterizing the navigation information, and further configured to send the dataset by way of a specified communication interface;

an image determination unit, which can be coupled with respect to signals with an optical display device of the vehicle, the image determination unit configured to:

receive a specified dataset which is transmitted by way of a specified communication interface, wherein the dataset consists of only non-graphic text data,

as a function of the received dataset, determine pixel values for at least a portion of pixels of a digital image and/or of a graphic element, and

determine a signalization signal for signalizing the pixel values of the pixels by means of the optical display device;

a specified communication interface which, with respect to signals, couples the data determination unit and the image determination unit; and

at least one optical display device which is coupled, with respect to signals, with the image determination unit and which is designed for receiving a signalization signal determined by the image determination unit and for signalizing.

12. The display system according to claim 11 , wherein the optical display device is coupled with respect to signals with the image determination unit by way of a specified multimedia interface.
