Abstract:
1. A method of detecting a picture repetition mode of film material comprising a series of consecutive fields, the method comprising the following steps: establishing a motion parameter pattern for said film material; comparing said pattern with a number of predetermined motion parameter patterns; and determining said picture repetition mode using the result of the preceding step, characterized in that said establishing step comprises the sub-steps: identifying a plurality of different objects within said consecutive fields, an object being defined as an image portion of said consecutive fields that can be described with a single motion model; and establishing a motion parameter pattern for each one of said objects within said consecutive fields, in that said comparing step comprises comparing each established motion parameter pattern with a number of predetermined motion parameter patterns, in that said determining step comprises determining said picture repetition mode for each one of said objects using the result of the comparing step.
