<p>PROBLEM TO BE SOLVED: To measure the speed of an object from one image generated by imaging the object.SOLUTION: An image processor includes image acquisition means 251 for acquiring an image from a camera that images an object of a target of speed measurement, edge extraction means (edge vector calculation means 254, edge determination means 255) for extracting an edge of the image acquired by the image acquisition means 251, blur amount calculation means 257 for calculating the blur amount of the edge extracted by the edge extraction means, and speed calculation means (blur amount/luminance image generation means 258, speed calculation means 25a) for calculating the speed of the object on the basis of the blur amount calculated by the blur amount calculation means 257, and correlation information between a blur amount of an image of the moving object from the camera and the speed of the moving object.</p> |
