1. A method of tracking an object, the method comprising:
- setting a plurality of patterns having various sizes, according to a distance from a horizon in an image to a plurality of pixels corresponding to the plurality of patterns in the image captured by a camera;
extracting an object matching one of the plurality of patterns having various sizes, while scanning the image using the plurality of patterns having various sizes; and
displaying information about a position of the extracted object in the image,wherein the setting the plurality of patterns comprises;
detecting the horizon from the image;
obtaining information about a height of the camera;
obtaining information about an actual size of the object; and
setting the plurality of patterns having various sizes to be used for scanning the image using the distance from the horizon in the image to the plurality of pixels in the image, the obtained information about the height of the camera, and the obtained information about the actual size of the object.
