Method and display system for operating a projection display system in a mobile device

A display system for a motor vehicle, the display system comprising:

• a projection device including a display device, which is configured to output image-bearing light for projecting a display image into an eye area of a user via a display surface;
• a combiner surface configured to reflect the image-bearing light into the eye area of the user;
• and
• a data processing device configured to
• obtain an eye pose of the user,
• transform the display image to be displayed before the display on the display surface based on a post-transformation matrix so that local flaws in a surface section of the combiner surface which result in a distortion or a fuzziness of a perception image perceptible by the user are compensated for, wherein the surface section depends on the eye pose of the user and corresponds to detail from the combiner surface, via which the display image is perceived by the user, and
• output a post-transformed display image via the display device;
• wherein the data processing device is configured to post-transform the display image to be displayed so that the post-transformed display image is provided which compensates for local flaws that correspond to deviations from a global curvature geometry.

• output a post-transformed display image via the display device;
• wherein the data processing device is configured to correct brightness values of pixels of the post-transformed display image pixel-by-pixel depending on a respective brightness value of pixels of a surroundings image detail.

A method for operating a display system for a motor vehicle, which includes a projection device having a display device, which is configured to output image-bearing light for projecting a display image into an eye area of a user via a display surface, and a combiner surface configured to reflect the image-bearing light into the eye area of the user, the method comprising:

• determining an eye pose of the user;
• transforming a display image to be displayed before the display on the display surface based on a post-transformation matrix, so that local flaws in a surface section of the combiner surface, which result in a distortion or a fuzziness of a perception image perceptible by the user, are compensated for, wherein the surface section depends on the eye pose of the user and corresponds to detail from the combiner surface, via which the display image is perceived by the user;
• and
• outputting a post-transformed display image via the display device;
• wherein brightness values of pixels of the post-transformed display image are corrected pixel by pixel depending on a respective brightness value of pixels of a surroundings image detail, wherein the surroundings image detail corresponds to a detail from a surroundings image captured by a surroundings camera, which is perceived by the user through the surface area of the combiner surface.
