Abstract:
1. A method for detecting a motion of an object using an image recording system which includes an image sensor, comprising: performing a first reset and a second reset at a first time interval during an exposure of the image sensor; measuring a first extent of a first region of constant brightness from an image of an object detected by the image sensor; and ascertaining the motion of the object at a first point in time from a relationship between (i) the measured first extent and (ii) the first time interval between the first and second resets; wherein the motion of the object is ascertained from a single image; performing at least one third reset at an additional time interval during the exposure of the image sensor; measuring a second extent of a second region of constant brightness from the image of the object; and ascertaining the motion of the object at an additional point in time from a relationship between (i) the measured second extent and (ii) the additional time interval between the second reset and the third reset; wherein a change in the motion of the object is determined based on the motion of the object at the first point in time and the motion of the object at the additional point in time.
