1. An image display method for displaying a combined image of a vehicle, the method comprising:
- capturing images corresponding to areas surrounding a vehicle using a corresponding plurality of cameras fixedly mounted to the vehicle;
calculating a plurality of displacement vectors for a plurality of points on each of the images captured by the cameras upon the application of a load to the vehicle sufficient to change an attitude of any of the plurality of cameras on the vehicle;
determining image borderlines between two adjacent images such that a difference in the directions of displacement vectors in the neighborhood of each image borderline does not exceed a predetermined angle;
combining the captured images into a virtual top-view image of the vehicle; and
displaying the virtual top-view image on a display device.

Abstract
An image display method for displaying a combined image by capturing images at areas surrounding a vehicle includes a) calculating a plurality of displacement vectors for a plurality of points taken on images captured by a plurality of cameras upon the application of a load that changes the attitude of a camera on the vehicle, and b) determining each image borderline between two adjacent images such that a difference in the directions of displacement vectors in the neighborhood of each image borderline between two adjacent images does not exceed a predetermined angle.
