Abstract

A display system for a commercial vehicle, having a capturing unit for acquiring image data of the vehicle environment, a calculation unit and a display unit for displaying an image to be displayed with an image portion. The calculation unit is adapted to carry out a modification of the image data acquired by the capturing unit and to supply the modified image data to the display unit for display. The modification uses overlaying or superimposing of an overlay portion on the image portion of the image to be displayed, wherein the overlay portion is positioned within or directly adjacent to the image portion, and wherein the image portion further includes a measuring portion. An image characteristic of the image portion is acquired in the measuring portion. The calculation unit is adapted to determine an overlay portion characteristic dependent on the acquired image characteristic.

First claim

What is claimed is:

1. A display system for a vehicle, comprising:
an image capturing unit for capturing image data of the vehicle environment;
a calculation unit, and
a display unit for displaying an image to be displayed, the image to be displayed having at least one image portion, the at least one image portion being displayed on the display unit;
wherein the calculation unit is adapted to carry out a modification of the image data captured by the image capturing unit and to supply the modified image data to the display unit for display,
wherein the modification includes overlaying or superimposing an overlay portion for display by the display unit on at least a portion of the image to be displayed on the display unit, the overlay portion being displayed on the display unit so that the overlay portion is displayed at a location on the display unit within or directly adjacent to a display location of the at least one image portion,
wherein each of the at least one image portion, has a sub-region adjacent to the overlay portion of the respective at least one image portion and which forms a measuring portion at which an image characteristic of the at least one image portion that is displayed on the display unit is acquired, the image characteristic being calculated by the calculation unit based on an analysis of a portion of the image data: (a) captured by the image capturing unit to form the image displayed on the display unit, and (b) corresponding to the measurement portion of the displayed at least one image portion, and wherein the calculation unit is adapted to change an overlay portion characteristic based on a result of the analysis of the image data by the calculation unit, the changed overlay portion characteristic including at least one selected from the group of: color shade, brightness, contrast, saturation and transparency, and
wherein the calculation unit is adapted to determine the overlay portion characteristic time-delayed with regard to the acquisition of the image characteristic of the at least one image portion, if a certain characteristic of the at least one image portion is present for a certain period of time.

2. The display system according to claim 1 , wherein the at least one image portion comprises a plurality of image portions and wherein the overlay portion comprises a separating portion between plural image portions and/or a frame around one image portion.

3. The display system according to claim 2 , wherein the overlay portion comprises a superimposition portion which entirely or at least partly overlaps the at least one image portion.

4. The display system according to claim 2 , wherein the measuring portion is within or directly adjacent to the overlay portion in the at least one image portion.

5. The display system according to claim 2 , wherein the calculation unit is provided in the image capturing unit and/or in the display unit.

6. The display system according to claim 2 , wherein a processing unit (ECU) is provided, and wherein the calculation unit is, at least partly, provided in the processing unit (ECU).

7. The display system according to claim 2 , wherein the calculation unit is adapted to map the image characteristic of the at least one image portion to the overlay portion characteristic by a mathematical function.

8. The display system according to claim 1 , wherein the overlay portion comprises a superimposition portion which entirely or at least partly overlaps the at least one image portion.

9. The display system according to claim 1 , wherein the measuring portion is within or directly adjacent to the overlay portion in the at least one image portion.

10. The display system according to claim 1 , wherein the acquired image portion characteristic is a characteristic regarding color shade, brightness, contrast and saturation, or a combination of these characteristics.

11. The display system according to claim 1 , wherein the calculation unit is provided in the image capturing unit and/or in the display unit.

12. The display system according to claim 1 , wherein a processing unit (ECU) is provided, and wherein the calculation unit is, at least partly, provided in the processing unit (ECU).

13. The display system according to claim 12 , wherein size and/or position and/or type of the overlay portion are changed dependent on current vehicle driving parameters.

14. The display system according to claim 13 , wherein at least two image portions are provided, which image portions are horizontally and/or vertically separated from each other by the overlay portion.

15. The display system according to claim 12 , wherein at least two image portions are provided, which image portions are horizontally and/or vertically separated from each other by the overlay portion.

16. The display system according to claim 1 , wherein at least two image portions are provided, which image portions are horizontally and/or vertically separated from each other by the overlay portion.

17. The display system according to claim 1 , wherein the calculation unit is adapted to map the image characteristic of the at least one image portion to the overlay portion characteristic by a mathematical function.
