IMAGE DISPLAY METHOD AND IMAGE DISPLAY APPARATUS
First Claim
1. An image display method for displaying a combined image by capturing images at areas surrounding a vehicle using a plurality of cameras, and combining the captured images into a virtual top-view image of the vehicle, the image display method comprising:
- calculating a plurality of displacement vectors for a plurality of points taken on the images captured by the cameras upon the application of a load that changes the attitude of a camera on the vehicle; and
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.

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.
