## Abstract

Provided is a vehicle periphery monitoring system that facilitates a driver's understanding about a photographing direction of an object which appears in an overlapping area of a bird's-eye view image generated from multiple photographed images. A displaying bird's-eye view image is generated by combining bird's-eye view image segments generated from the multiple photographed images photographed in a partially overlapping manner with superimposing mutually overlapped areas thereof. In displaying the displaying bird's-eye view image, a boundary-added bird's-eye view image formed by adding a boundary indicator to the overlapping area of the bird's-eye view image is displayed on a display unit; then, a merged superimposed image is displayed. The merged superimposed image is obtained by merging the overlapped areas of the bird's-eye view image according to a preset merger relationship.

## Claims

### Claim 1

A vehicle periphery monitoring system comprising:
a bird's-eye view image generation section generating bird's-eye view image segments from multiple photographed images photographed to be partially overlapped in a vehicle circumference direction;
a boundary indicator addition section adding a boundary indicator indicating a boundary area of the bird's-eye view image segments adjacent each other to an overlapped area of the bird's-eye view image segments;
a merger section generating a merged overlapped image by merging mutually overlapped areas of the bird's-eye view image segments according to a preset merger relationship;
a displaying bird's-eye view image generation section generating a merged bird's-eye view image containing a boundary-added bird's-eye view image having the boundary indicator and the merged overlapped image as a displaying bird's-eye view image;
a displaying section displaying the displaying bird's-eye view image; and
a displaying image determination section displaying the merged bird's-eye view image in the displaying section after displaying the boundary-added bird's-eye view image therein.

### Claim 2 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein the boundary-added bird's-eye view image is generated as the overlapped area in the boundary-added bird's-eye view image appropriates the overlapped area of one bird's-eye view image segment; and the merged bird's-eye view image is generated as this overlapped area is replaced by the merged overlapped image generated by the merger section.

### Claim 3 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein the displaying image determination section is configured to display the merged bird's-eye view image after lapse of a period set after displaying of the boundary-added bird's-eye view image in the displaying section.

### Claim 4 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein in a display switchover process from displaying of the boundary-added bird's-eye view image to displaying of the merged bird's-eye view image as the displaying bird's-eye view image, displaying is switched over to displaying of the merged overlapped image progressively and concentrically from vicinity of the vehicle.

### Claim 5 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein in a display switchover process from displaying of the boundary-added bird's-eye view image to displaying of the merged bird's-eye view image as the displaying bird's-eye view image, displaying is switched over sequentially from displaying of an area of the boundary indicator to displaying of the merged overlapped image.

### Claim 6 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein the boundary indicator is displayed with emphasis in a display switchover process from displaying of the boundary-added bird's-eye view image to displaying of the merged bird's-eye view image as the displaying bird's-eye view image.

### Claim 7 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein in the boundary-added bird's-eye view image, no merger process is effected for the overlapped area where the multiple bird's-eye view image segments are overlapped with each other.

### Claim 8 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein the boundary-added bird's-eye view image is displayed after startup of the vehicle periphery monitoring system.

### Claim 9 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein the merged bird's-eye view image is added with a boundary indicator.

### Claim 10 (depends on 9)

The vehicle periphery monitoring system according to claim 9, wherein the boundary indicator added to the merged bird's-eye view image is semitransparent.

### Claim 11 (depends on 9)

The vehicle periphery monitoring system according to claim 9, wherein the boundary indicator added to the merged bird's-eye view image is shorter than the boundary indicator added to the displaying bird's-eye view image.

### Claim 12 (depends on 9)

The vehicle periphery monitoring system according to claim 9, wherein the boundary indicator added to the merged bird's-eye view image is a dotted line.

### Claim 13 (depends on 9)

The vehicle periphery monitoring system according to claim 9, wherein the boundary indicator added to the merged bird's-eye view image is thinner than the boundary indicator added to the displaying bird's-eye view image.

### Claim 14 (depends on 1)

The vehicle periphery monitoring system according to claim 1, wherein the merged bird's-eye view image is added with a boundary indicator in a displaying form different from a displaying form of the boundary indicator of the displaying bird's-eye view image.
