摘要： Provided are an apparatus and method for processing motion picture and a record medium, which decompose a motion picture into unit frames and insert copyright information into the unit frames, enabling to determine the infringement of copyright when the motion picture is illegally circulated. The apparatus includes a processing unit, a merging unit and an output unit. The processing unit decomposes a motion picture into a plurality of unit frames, and generates a main frame, a sub-frame including copyright information for the motion picture and a degree frame which is paired with the sub-frame, based on the unit frames. The merging unit merges the sub-frame into the main frame according to a degree of mergence of the degree frame. The output unit continuously outputs the merged frames in time order.
