Image processing device
First Claim
1. An image processing device for calculating an optical flow on the basis of image information within a window for a processing target using a plurality of images captured at different times, comprising:
- position acquisition means which acquires position information of the processing target; and
setting means which sets a size of a window for calculating an optical flow on the basis of the position information acquired by the position acquisition means;
wherein the setting means increases the window size as a lateral position difference becomes larger, the lateral position difference being a difference between an image capture position where a camera is attached and a position where the processing target exists.

Abstract
An image processing device for improving the accuracy of optical flow calculation when an optical flow is calculated in a window unit. An image processing device for calculating an optical flow on the basis of image information within a window for a processing target using a plurality of images captured at different times includes position acquisition means which acquires position information of the processing target and setting means which sets a size of a window for calculating an optical flow on the basis of the position information acquired by the position acquisition means.
