Image processing apparatus and method, recording medium, and program |
摘要 |
An image processing apparatus that performs image processing on a first image and a second image includes a dividing unit dividing the first image into a plurality of blocks; a first motion-vector calculator calculating first motion vectors representing movements from the blocks of the first image to corresponding regions of the second image; a second motion-vector calculator calculating second motion vectors representing movements of the blocks that occur when the blocks are transformed based on a first positional-relationship parameter representing positional relationship between the first image and the second image; a difference-vector calculator calculating difference vectors representing differences between the first motion vectors and the second motion vectors; and an extracting unit extracting blocks including a moving object or blocks including a non-moving object based on distribution density of end points of the difference vectors.
