## Abstract

A periphery display control device includes: an image acquisition unit acquiring captured image data obtained by imaging a periphery of an own vehicle; a target acquisition unit acquiring a target position to which the own vehicle moves; an image generation unit generating a virtual viewpoint image while moving, based on a relative angle of the target position with respect to a movement direction of the own vehicle when moving to the target position, at least one of a virtual viewpoint set at a position facing the target position across the own vehicle and a gazing point when facing an area including at least one of the own vehicle and the target position from the virtual viewpoint in a state where a distance between and heights of the virtual viewpoint and the gazing point are maintained; and an output unit outputting the virtual viewpoint image to a display device.

## Claims

### Claim 1

A periphery display control device comprising:
at least one processor configured to implement:
an image acquisition unit configured to acquire captured image data obtained by imaging a periphery of an own vehicle;
a target acquisition unit configured to acquire a target position to which the own vehicle moves; an image generation unit configured to generate a virtual viewpoint image while moving, based on a relative angle of the target position with respect to a movement direction of the own vehicle when the own vehicle moves to the target position, at least one of a virtual viewpoint set at a position facing the target position across the own vehicle and a gazing point when facing an area including at least one of the own vehicle and the target position from the virtual viewpoint in a state where a distance between the virtual viewpoint and the gazing point is maintained and heights of the virtual viewpoint and the gazing point are maintained; and
an output unit configured to output the virtual viewpoint image to a display device, wherein the image generation unit sets the virtual viewpoint and the gazing point on an outer peripheral surface of a virtual cylinder set around the own vehicle.

### Claim 2 (depends on 1)

The periphery display control device according to claim 1, wherein
the image generation unit sets the virtual viewpoint on an outer peripheral surface of a virtual cylinder set around the own vehicle and sets the gazing point at a position corresponding to a vehicle center of the own vehicle.

### Claim 3 (depends on 2)

The periphery display control device according to claim 2, wherein
the image generation unit changes the height of the virtual viewpoint when the own vehicle completes movement to the target position.

### Claim 4 (depends on 1)

The periphery display control device according to claim 1, wherein
the image generation unit sets the virtual viewpoint on an outer peripheral surface of a virtual cylinder centered on the target position and sets the gazing point at the target position.

### Claim 5 (depends on 4)

The periphery display control device according to claim 4, wherein
the image generation unit changes the height of the virtual viewpoint when the own vehicle completes movement to the target position.

### Claim 6 (depends on 1)

The periphery display control device according to claim 1, wherein
the image generation unit changes the height of the virtual viewpoint when the own vehicle completes movement to the target position.
