PROBLEM TO BE SOLVED: To provide a technique for automatically correcting an incline of an image without using a special calibration pattern.SOLUTION: An image processing system comprises: calculation means of dividing an image photographed by an imaging device into right and left regions, and calculating a local gradient direction histogram to each of divided regions; estimation means of estimating a camera parameter showing a rotation amount of the imaging device based on the local gradient direction histogram; and correction means of correcting the image based on the estimated camera parameter.SELECTED DRAWING: Figure 1 |
