Abstract
A head-up display for a vehicle provides image warping. The head-up display comprises at least one sensor, an image generator, a display unit and a mirror unit. A correction unit is furthermore arranged following the image generator.
Claims16
A head-up display comprising:
- an image generator which generates an image,
- at least one sensor capable of detecting a fast change in position in at least one of the image, a pre-warped image signal, and a display signal,
- a display unit, and
- a correction unit for a mirror unit, wherein the correction unit is arranged following the image generator, and wherein the correction unit applies an offset to the at least one of the image, the pre-warped image signal, and the display signal that corresponds to the fast change in position, and wherein the offset is reduced according to a time constant.
1 more element
A method for the operation of a head-up display, comprising:
- generating image content to be displayed on the head-up display;
- pre-warping the image content according to optical boundary conditions of the head-up display;
- generating a display signal from the pre-warped image signal;
- detecting a fast change in position of the intersection point of the direction of view of a user with a surface of a mirror unit of the head-up display;
- applying of an offset corresponding to the fast change in position that has been detected in at least one of the image content, the pre-warped image signal, and the display signal;
- reducing the offset according to a lime constant;
- and
- displaying the display signal to which the offset has been one of directly and indirectly applied.

A computer comprising software code sections with instructions for:
- generating image content to be displayed on a head-up display;
- pre-warping the image content according to optical boundary conditions of the head-up display;
- generating a display signal from the pre-warped image signal;
- detecting a fast change in position of the intersection point of the direction of view of a user with a surface of a mirror unit of the head-up display;
- applying of an offset corresponding to the fast change in position that has been detected to at least one of the image content, the pre-warped image signal, and the display signal;
- reducing the offset according to a time constant;
- and
- displaying the display signal to which the offset has been one of directly and indirectly applied.
