At least one image registering unit records at least one series of images representing a subject. A control unit controls an operation sequence for the at least one image registering unit in such a manner that a subsequent data processing unit receives a repeating sequence of image frames there from, wherein each period (P) contains at least one image frame of a first resolution (501) and at least one image frame of a second resolution (602) being different from the first resolution (501). Based on the registered image frames, the data processing unit produces eye/ gaze tracking data with respect to the subject. |
