Method, head-up display and output system for the perspective transformation and outputting of image content, and vehicle
First Claim
1. A method for perspective transformation and display of a rendered image content by a head-up display, comprising the acts of:
- dividing the rendered image content into a plurality of tiles;
transforming individual ones of the plurality of tiles by perspective transformation;
storing the perspectively transformed tiles in a buffer memory;
combining the perspectively transformed tiles into a transformed image content; and
projecting the perspectively transformed image content onto a projection surface assigned to the head-up display,whereinonly a portion of the individual ones of the plurality of tiles is perspectively transformed,the portion of the individual ones of the plurality of tiles is perspectively transformed includes individual ones of the plurality of tiles which are changed relative to tiles of a perspectively transformed image previously stored in the buffer memory, andduring the act of combining the individual perspectively transformed tiles, the remaining individual ones of the plurality of tiles which were not changed relative to the perspectively transformed image previously stored in the buffer memory are retrieved from the buffer memory and combined with the portion the individual ones of the plurality of tiles perspectively transformed to form the perspectively transformed image content.

Abstract
A method, a head-up display and a display system for the perspective transformation and displaying of rendered image content, as well as a corresponding vehicle, are provided. In the perspective transformation and outputting method, the image content to be displayed is subdivided into a plurality of tiles, and the individual tiles are each transformed in perspective using perspective transformation. The individual tiles that have been transformed in perspective are then combined to form a transformed image content, and the image content transformed in perspective is projected onto a projection area of the head-up display or displayed on a display unit.

1. A method for perspective transformation and display of a rendered image content by a head-up display, comprising the acts of:
-
dividing the rendered image content into a plurality of tiles; transforming individual ones of the plurality of tiles by perspective transformation; storing the perspectively transformed tiles in a buffer memory; combining the perspectively transformed tiles into a transformed image content; and projecting the perspectively transformed image content onto a projection surface assigned to the head-up display, wherein only a portion of the individual ones of the plurality of tiles is perspectively transformed, the portion of the individual ones of the plurality of tiles is perspectively transformed includes individual ones of the plurality of tiles which are changed relative to tiles of a perspectively transformed image previously stored in the buffer memory, and during the act of combining the individual perspectively transformed tiles, the remaining individual ones of the plurality of tiles which were not changed relative to the perspectively transformed image previously stored in the buffer memory are retrieved from the buffer memory and combined with the portion the individual ones of the plurality of tiles perspectively transformed to form the perspectively transformed image content. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A head-up display for the perspective transformation and display of a rendered image content, comprising:
-
a control unit including a first module configured to divide the rendered image content into a plurality of tiles and to store the perspectively transformed tiles in a buffer memory, a second module configured to transform individual ones of the plurality of tiles by perspective transformation, and a third module configured to combine the individual perspectively transformed tiles into a transformed image content; and a projection unit configured to project the perspectively transformed image content onto a projection surface assigned to the head-up display, wherein the second module is configured to perspectively transform only a portion of the individual ones of the plurality of tiles, the portion of the individual ones of the plurality of tiles includes individual ones of the plurality of tiles which are changed relative to tiles of a perspectively transformed image previously stored in the buffer memory, and the third module is configured to, during the combining of the individual perspectively transformed tiles, retrieve from the buffer memory previously stored remaining individual ones of the plurality of tiles which were not changed relative to the perspectively transformed image, and combine previously stored remaining individual ones of the plurality of tiles which were not changed relative to the perspectively transformed image with the individual ones of the plurality of tiles perspectively transformed to form the perspectively transformed image content.
