Claim 0:
1. A method for operating a visual field display apparatus for a motor vehicle, which visual field display apparatus is designed to generate a projection light beam with display content and to project the display content onto a partly transparent reflecting projection screen of the motor vehicle such that a virtual display image superimposed into a visual field of a user is generated therebehind,
the method comprising:
ascertaining vertical image element edges, or image element edges with a vertical component, in the virtual display image to be superimposed; and
tilting the image element edges thus ascertained to a respective tilt angle with respect to a vertical direction, which tilt angle is adapted in such a way that horizontally offset double images of the respective image element edges, which are caused by a double reflection of the projection light beam at two optical interfaces of the projection screen, are overlaid for the user in the virtual display image and consequently appear substantially sharp.
