Patent ID: 7697029

Claim:
An image display apparatus that converts a viewpoint of an original image of a driving environment obtained with an imaging device based on a depression angle of the imaging device to display a bird's eye view image, the image display apparatus comprising: a road surface condition detection device that detects a distance between the imaging device and a road surface; a depression angle correction calculation device that adds a correction angle to the depression angle of the imaging device so as to make the distance between the imaging device and the road surface constant in response to a change in distance between the imaging device and the road surface detected by the road surface condition detection device; a depression angle correction modification device that reduces the correction angle; and a three-dimensional object detection device that detects a three-dimensional object present on the road surface, wherein the depression angle correction modification device reduces the correction angle if it is determined that the distance between the imaging device and the road surface detected by the road surface condition detection device is equal to a distance between the three-dimensional object detected by the three-dimensional object detection device and the imaging device.
