Method and Display System for Operating a Projection Display System in a Mobile Device

A display system for a motor vehicle includes a projection device having a display device which is configured to output image-bearing light for projecting a display image in an eye area of a user via a display surface. A combiner surface reflects the image-bearing light into the eye area of the user. A device configured to obtain an eye pose of the user transforms a display image with the aid of 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. A display image is displayed on the display surface using brightness values so that a homogeneous and high contrast representation results based on the eye pose of the user and the detail of the combiner surface. The transformed display image is output via the display device.
