Driver Assistance System with Variable Image Resolution

Driver assistance system (101) for a vehicle (100), the driver assistance system comprising:

• a camera (102) having a variable or dynamic sensor resolution configured to record images of a vehicle environment;
• wherein the camera is configured to record images of a first type (200) of the vehicle environment (201) in a first recording mode;
• wherein the camera is configured to record images of a second type (204) of a section (203) of the vehicle environment in a second recording mode, wherein the section of the vehicle environment recorded in the images of the second type is of a smaller area of the vehicle environment compared to a larger area of the vehicle environment recorded in the images of the first type;
• wherein the images of the second type are recorded at a higher resolution than the images of the first type, wherein the images of the first type are binned images and the images of the second type are non-binned images;
• wherein the camera is configured to automatically switch between the first recording mode and the second recording mode, wherein the camera is configured to iteratively record the images of the first type and the images of the second type according to predetermined intervals;
• wherein the driver assistance system is configured to analyze at least one of the images of the first type to determine the section of the vehicle environment;
• and
• wherein the driver assistance system is configured to determine a distant area around a vanishing point of the vehicle environment, wherein the distant area is at a far-range of the vehicle environment, and wherein the driver assistance system is configured to locate the section of the vehicle environment around the vanishing point;
• and
• wherein the vanishing point is determined through a determination of a crossing point of an extrapolated border of a road with a horizon recorded by the camera.
