IMAGE GENERATION APPARATUS
First Claim
1. An image generation apparatus that is used in a vehicle and generates an image that shows a periphery of the vehicle, the image generation apparatus comprising:
- an input that acquires shot images from a plurality of cameras, each of which captures the periphery of the vehicle in a different direction;
a controller that determines a traveling direction of the vehicle;
a generator that generates a composite image including a first area and a second area in a seamless manner based on the shot images, the first area showing the periphery of the vehicle viewed from a virtual viewpoint that is set looking down at the vehicle, the second area showing an area that includes an outside of the first area and is in a direction opposite to the determined traveling direction; and
an output that transmits a display image including the composite image to a display apparatus to display the display image on the display apparatus.

Abstract
A shift determining part of an image display system determines a traveling direction of a vehicle. A composite image generator generates a composite image that shows a periphery of the vehicle and an area that is in a direction opposite to the determined traveling direction of the vehicle in a seamless manner. The periphery is viewed from a virtual viewpoint that is set looking down at the vehicle. A display displays a display image including the composite image. Since the display image includes the composite image that shows the area that is in the direction opposite to the determined traveling direction of the vehicle, a user can notice an object that exists in the direction opposite to the traveling direction of the vehicle by looking at the display image.

7. An image generation apparatus that is used in a vehicle and generates an image that shows a periphery of the vehicle, the image generation apparatus comprising:
-
an input that acquires shot images from a plurality of cameras, each of which captures one of an area in front of the vehicle and an area behind the vehicle; a controller that determines a traveling direction of the vehicle; a generator that generates a display image based on the shot images; and an output that transmits the display image to a display apparatus to display the display image on the display apparatus, wherein the generator generates as the display image, a first display image that shows the area in front of the vehicle when the determined traveling direction of the vehicle is a forward direction, and selectively one of a second display image and a third display image in conformity with a user'"'"'s operation when the determined traveling direction of the vehicle is a backward direction, the second display image showing the area behind the vehicle, the third display image showing the area in front of the vehicle in a different form than the first display image. - View Dependent Claims (8, 9, 10)

11. An image generation apparatus that is used in a vehicle and generates an image that shows a periphery of the vehicle, the image generation apparatus comprising:
-
an input that acquires a shot image from a side camera that captures a side area of the vehicle; a controller that determines a traveling direction of the vehicle; a detector that detects a state of a side mirror of the vehicle; a generator that generates a display image that shows the side area covering the determined traveling direction of the vehicle based on the shot image acquired from the side camera, when the side mirror is retracted; and an output that transmits the display image to a display apparatus to display the display image on the display apparatus. - View Dependent Claims (12)

13. An image generation method for use in a vehicle and for generating an image that shows a periphery of the vehicle, the image generation method comprising the steps of:
-
(a) acquiring shot images from a plurality of cameras, each of which captures the periphery of the vehicle in a different direction; (b) determining a traveling direction of the vehicle; (c) generating a composite image that shows a first area and a second area in a seamless manner based on the shot images, the first area showing the periphery of the vehicle viewed from a virtual viewpoint that is set looking down at the vehicle, the second area showing an area that includes an outside of the first area of the vehicle and is in a direction opposite to the determined traveling direction; and (d) displaying a display image that includes the composite image.
