Abstract
A method for automatically focusing a camera (10), having an optical unit (11) for focusing and a driveable actuator unit (12) for adjusting the optical unit (11), on at least one object (20, 21), wherein an image is recorded by the camera, wherein the at least one object (20, 21) in the image is automatically detected by the camera (10) via image content analysis, wherein a distance (120, 121) between the at least one object (20, 21) and the camera (10) is automatically ascertained, and wherein the driveable actuator unit (12) is driven in a targeted manner based on the ascertained distance (120, 121) such that the optical unit (11) is focused on the at least one object (20, 21).
