Claim 5:
6. The video processing device according to claim 1, wherein the one movement information estimation that is selected when the scene class identified by the scene class information represents a first-person viewpoint video is performed to:
calculate optical flow in a first region of the input video content, the first region reflecting a movement experienced by a photographer in a traveling direction;
calculate optical flow in a second region of the input video content, the second region reflecting a movement experienced by the photographer in a direction other than the traveling direction; and
determine a weighted sum of a representative value of the optical flow in the first region and a representative value of the optical flow in the second region and output the determined weighted sum as a movement vector for the video content.
