Abstract

The invention relates to a method for adapting a brightness (28) of a high-contrast image (20, 22) of an environmental region (9) of a motor vehicle (1) including the following steps of: a) capturing a first image with a first camera parameter of a camera system (2) of the motor vehicle (1) and a second image with a second camera parameter of the camera system (2) by means of the camera system (2), b) generating a first high-contrast image (20) of the environmental region (9) with the first image and the second image, c) determining a high-contrast brightness value (23) of the first high-contrast image (20), d) comparing the high-contrast brightness value (23) to a predetermined high-contrast target brightness value, e) adapting the first high-contrast image (20) depending on the comparison according to step d), f) determining a first brightness value of the first image and/or a second brightness value of the second image, g) comparing the first brightness value to a first target brightness value (26) and/or the second brightness value to a second target brightness value (27), h) adapting the first camera parameter and/or the second camera parameter depending on the comparison according to step g), i) capturing a third image of the environmental region (9) with the adapted first camera parameter and a fourth image of the environmental region (9) with the adapted second camera parameter by means of the camera system (2), j) generating a second high-contrast image (22) of the environmental region (9) with the third image and the fourth image, k) providing the second high-contrast image (22) as a high-contrast image (20, 22) adapted in brightness for representing the environmental region (9) of the motor vehicle (1).
