Abstract
In a device for correcting picture instabilities in film scanners, at least one motion vector describing the motion of at least one part of the picture between two scanned pictures is derived and an actuator situated in the path of the video signals obtained by scanning is controlled in a manner dependent on said motion vector, in each case the at least one motion vector of successive pictures being fed to a filter, the filter containing a plurality of registers, to which the at least one motion vector can be fed and which are assigned a state variable which is set if the respective register content is valid, the contents of the registers with a set state variable being accumulated by a new motion vector when the latter arrives, the state variable being reset if the state variable was set before the arrival of the new motion vector and the content of the respective register exceeds a predetermined threshold, the content of one of the registers with a reset state variable being set to zero and the state variable being set to one and an average value being formed from the contents of the registers with a set state variable, said average value being fed to the actuator with an opposite sign.
