Abstract
A method of automatically equalizing image data generated by a surround-view camera system of a vehicle. The method includes receiving a first, second, third, and fourth data set including image data corresponding to a front, left, right, and rear field of view of the vehicle, respectively. The method also includes identifying a darkest region in the first, second, and third data sets and adjusting a brightness of the image data included in the first, second, and third data sets based on the darkest region. The method further includes adjusting a brightness of the image data included in the fourth data set based on a comparison of the brightness of the image data included in the fourth data set and the adjusted brightness of the image data included in the second and third data sets.
