Abstract: The present disclosure relates to a method, a computer program comprising instructions and a device for reducing masking by a virtual image of a head-up display of a transport. The disclosure additionally relates to a head-up display for a transport in which such a method or such a device is used. In a first step, a horizon is determined. Afterward, an image to be displayed is subdivided into a plurality of partial areas. In this case, the partial areas are rectangular and their vertical extent varies over the area of the image to be displayed. For the individual partial areas, masking areas are determined and checking is carried out to ascertain whether the determined masking area exceeds a permissible size for at least one of the partial areas. If this is the case, a warning signal is output. Finally, at least one measure for reducing the masking is implemented in response to the warning signal.

Abstract: The present disclosure relates to a method, a computer program comprising instructions and a device for reducing masking by a virtual image of a head-up display of a transport. The disclosure additionally relates to a head-up display for a transport in which such a method or such a device is used. In a first step, a horizon and/or a vanishing point is determined. Afterward, an image to be displayed is subdivided into a plurality of partial areas. In this case, the partial areas are trapezoidal and their size varies over the area of the image to be displayed. For the individual partial areas, masking areas are determined and checking is carried out to ascertain whether the determined masking area exceeds a permissible size for at least one of the partial areas. If this is the case, a warning signal is output. Finally, at least one measure for reducing the masking is implemented in response to the warning signal.

Abstract: A head-up display having a display apparatus comprising a picture generating unit comprising a display element for displaying an image and a driver for the display element, an optical unit for projecting the image onto a projection surface, and an image control unit for controlling the display element via the driver. The picture generating unit further comprises an image brightness monitoring device, which has an image signal input connected to an image signal output of the image control unit and has a signal output connected to a signal input of the display element.
