description A method for determining a rotational speed of a rotatably mounted component of a machine is disclosed, wherein image data of a marked region of the machine component are obtained in the form of a plurality of frames via a video camera, and the image data are evaluated, in order to determine the periodicity of the rotation of the machine component from the change over time of the image data in the frames of the machine component. The video camera is configured by selecting an active region for obtaining the image data from the total number of pixels of the video camera, in which an observation area is imaged, which is passed through by the marked region during the rotation of the machine component, wherein the active region comprises only a portion of the total number of pixels of the video camera, to increase the frame rate correspondingly.
