Image display device and method
First Claim
1. An image display device for a vehicle, comprising:
- multiple image pickup devices that capture multiple direct images of the vehicle surroundings in different directions;
an image-processing device that composes a bird'"'"'s-eye view image using the multiple direct images; and
a display device that provides at least one of the bird'"'"'s-eye view image and a direct image picked up by one of the multiple image pickup devices to the driver; and
wherein the image-processing device displays simultaneously on the display device at least two discrete images, a first of the at least two discrete images including the bird'"'"'s-eye view image and a second of the at least two discrete images including a direct image picked up by only one of the multiple image pickup devices;
wherein the image-processing device displays the second of the at least two discrete images with a display size larger than a display size of the first of the at least two discrete images; and
wherein the image-processing device selects the second discrete image to be displayed in response to at least one of a position of a detected obstacle and a gear change of the vehicle.

Abstract
A device and method that allows any differences between the relative position of an obstacle as it appears in a bird'"'"'s-eye view image and its actual relative position can be checked on the same screen. In order to display the vehicle surroundings to the driver, multiple direct images obtained from multiple pickup devices, preferably cameras, oriented in different directions are used to compose a bird'"'"'s-eye view image from which the vehicle surroundings can be known at a glance. The bird'"'"'s-eye view image and a direct image picked up in the direction of an obstacle with respect to the vehicle are simultaneously displayed when the obstacle is detected in the vicinity of the vehicle.

12. An image display device for a vehicle, comprising:
-
means for capturing vehicle surroundings from a plurality of directions; means for composing a bird'"'"'s-eye view image from multiple images of the vehicle surroundings so captured; means for detecting a presence of any obstacles in the vicinity of the vehicle; means for simultaneously displaying at least two discrete images to the driver, a first of the at least two discrete images including the bird'"'"'s-eye view image and a second of the at least two discrete images including a single direct image picked up in a direction of an obstacle in response to detection of the obstacle; and means for sizing the second of the at least two discrete images to have a larger display size than a display size of the first of the at least two discrete images.
