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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The head-up display as claimed in claim 1, wherein the sensor comprises at least one sensor with a low latency time which is connected to an input of the correction unit. ### Claim 3 (depends on 1) The head-up display as claimed in claim 1, wherein the at least one sensor is one of: a gyro-sensor, a steering angle sensor and a braking force sensor that is connected to an input of the correction unit. ### Claim 4 (depends on 1) The head-up display as claimed in claim 1, wherein the image generator comprises multiple elements with different latency times, and the correction unit follows the element with the highest latency time. ### Claim 5 (depends on 1) The head-up display as claimed in claim 1, wherein a high-pass filter is present for the signal of the at least one sensor. ### Claim 6 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. ### Claim 7 (depends on 6) The method as claimed in claim 6, further comprising: detecting a 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; generating the image content to be displayed on the head-up display; pre-warping of the image content corresponding to optical boundary conditions of the head-up display and to a low-frequency component of the change in position; 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 the mirror unit of the head-up display; applying an offset corresponding to the fast change in position that has been detected to one of the image content, the pre-warped image signal, and the display signal; and displaying the display signal to which the offset has been one of directly and indirectly applied. ### Claim 8 (depends on 6) The method as claimed in claim 6, further comprising detecting the fast change in position with a gyro-sensor. ### Claim 9 (depends on 6) The method as claimed in claim 6, further comprising detecting the fast change in position with a signal of an eye movement sensor. ### Claim 10 (depends on 9) The method as claimed in claim 9, further comprising filtering the fast change in position with the signal of the eye movement sensor. ### Claim 11 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. ### Claim 12 (depends on 11) The computer as claimed in claim 11, further instructions comprising: detecting a 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; generating the image content to be displayed on the head-up display; pre-warping of the image content corresponding to optical boundary conditions of the head-up display and to a low-frequency component of the change in position; 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 the mirror unit of the head-up display; applying an offset corresponding to the fast change in position that has been detected to one of the image content, the pre-warped image signal, and the display signal; and displaying the display signal to which the offset has been one of directly and indirectly applied. ### Claim 13 (depends on 11) The computer as claimed in claim 11, further instructions comprising detecting the fast change in position with a gyro-sensor. ### Claim 14 (depends on 11) The computer as claimed in claim 11, further instructions comprising detecting the fast change in position with a signal of an eye movement sensor. ### Claim 15 (depends on 14) The computer as claimed in claim 14, further instructions comprising filtering the fast change in position with the signal of the eye movement sensor. ### Claim 16 (depends on 11) The computer claimed in claim 11, further instructions comprising a non-volatile storage medium comprising the software code sections.
