MOTION ESTIMATION DEVICE, DEPTH ESTIMATION DEVICE, AND MOTION ESTIMATION METHOD

摘要

The motion estimation device according to one embodiment of the present invention is a motion estimation device (300) that uses multifocal image groups (226) corresponding to one scene and having different focal points to estimate the motion for multiple first regions included in the corresponding scene, and is equipped with: a cost value calculation unit (305), which uses the aforementioned multifocal image groups (226) to calculate, for each of the multiple first regions, a cost value that indicates the difference between the amount of blurring for the corresponding first region and a standard amount of blurring that has been set for each distance in the depth direction; and a motion estimation unit (306), which uses the aforementioned cost values to estimate the motion for the first regions corresponding to those cost values.
