Method for determining two-dimensional motion vector fields in an image sequence and image processing device for this purpose

摘要

A method of detecting two-dimensional motion vector fields in an image sequence comprises the steps of: - taking at least one image of a scene with a first exposure time; Recording the same scene with a second exposure duration that is longer than the first exposure duration, such that the image of the scene captured with the second exposure duration has a greater motion blur than the at least one image of the same scene taken with the first exposure duration, and determining two-dimensional motion vector field from the longer exposure image of the scene with higher motion blur taken with the second exposure duration with respect to the temporally associated with this image of the scene at least one captured with the first exposure time image of this scene with first exposure time.
