| Due to its mechanical nature motion picture film has to cope with inaccuracies in positioning the single image in the moment of exposure, projection and scanning. This is the reason for steadiness errors that manifest in a jitter of the whole image. This jitter is not limited to translations but may also include rotational and shearing motion components. The amplitude of these erroneous movements lies in the scope of modern film scanner resolution and thus is a problem of scanning motion picture film especially in real time. The proposed algorithm estimates motion parameters for every image including the steadiness error component. Based on the sequence of these motion parameters a correction signal can be calculated to suppress the subjective jitter of the motion picture. | |||||||||||||
