Abstract:
1. A motion vector calculation method in which multiple pieces of image data are input to calculate motion vectors between/among images, the method comprising: multi-resolution image generation processing for calculating and storing multi-resolution data up to a predetermined resolution level L (where L is a natural number) of the input multiple pieces of image data; input motion vector calculation processing for calculating input motion vectors for the resolution level L of a reference image; and processing for estimating motion vectors per resolution by using the reference image, a target image and the input motion vectors at the resolution level L calculated by the processings above to perform: wherein the motion vectors between the reference image and the target image are calculated by using the finally calculated motion vectors of the resolution level L as input motion vectors of a resolution level L-1, which is a higher resolution, and by repeating the processing for estimating motion vectors per resolution on image data having higher resolutions sequentially.
