## Abstract

The present invention relates to a display controlling device and method that is capable of achieving excellent ease in operations in relation to the display output of an in-vehicle display device. The device comprises an image acquiring means for acquiring a captured image of a vehicle's vicinity, a region setting means for setting a prescribed region between displaying means, installed within the vehicle's cabin and a position of a vehicle occupant within the cabin, a function setting means for setting a display function associated with a prescribed region, a viewpoint position detecting means for detecting a position relating to a viewpoint of the vehicle occupant, and an image controlling means for controlling the displaying means to display the captured image. When the position relating to the viewpoint is detected in a prescribed region, the controlling means executes the display function on the captured image displayed.

## Claims

### Claim 1

A display controlling device comprising:
a camera for acquiring a captured image wherein a vicinity of a vehicle has been imaged;
at least one display installed within a cabin of the vehicle; and
a processor communicatively coupled to the camera and the at least one display, wherein the processor is configured to:
set a prescribed region between the at least one display and a position wherein a vehicle occupant is within the cabin of the vehicle,
set a display function chosen by the vehicle occupant from among multiple display functions as the display function associated with the prescribed region,
detect a position relating to a viewpoint of the vehicle occupant, and
control the at least one display so as to display the captured image, wherein:
when the position relating to the viewpoint is detected as being in the prescribed region, the processor executes the display function on the captured image displayed by the at least one display.

### Claim 2 (depends on 1)

A display controlling device set forth in claim 1, wherein:
the processor generates a virtual view image that is an image of the outside of the vehicle that is calculated as being visible from the viewpoint of the vehicle occupant, by processing the captured image based on the position relating to the viewpoint of the vehicle occupant, and, if the position relating to the viewpoint is identified as being within the prescribed region, executes the display function on the virtual view image.

### Claim 3 (depends on 1)

A display control device set forth in claim 1, wherein:
the display function zooms the captured image.

### Claim 4 (depends on 3)

A display controlling device set forth in claim 3, wherein:
the processor sets a display function from the multiple display functions that zooms the captured image for a prescribed region that is set in the vicinity of the at least one display; and
the processor zooms the captured image, and causes the captured image to be displayed on the at least one display, when the position relating to the viewpoint moves toward the at least one display to enter into the prescribed region.

### Claim 5 (depends on 3)

A display controlling device set forth in claim 3, wherein:
the processor sets a plurality of divided regions, with different distances to the at least one display, in the prescribed region; and
the processor sets different enlargement ratios for the plurality of divided regions.

### Claim 6 (depends on 1)

A display controlling device set forth in claim 1, wherein:
the display function adds route information to the display of the captured image that is displayed on the at least one display.

### Claim 7

A display controlling method, performed by:
a display controlling device, for controlling display of at least one display that is installed within a cabin of a vehicle, including at least a processor communicatively connected to the at least one display, the display controlling method includes:
acquiring a captured image wherein the vicinity of the vehicle has been imaged;
setting a prescribed region between the at least one display and a position wherein a vehicle occupant is within the cabin of the vehicle;
setting a display function chosen by the vehicle occupant from among multiple display functions as the display function associated with the prescribed region;
detecting a position relating to a viewpoint of the vehicle occupant; and
controlling the at least one display so as to display the captured image, wherein:
when the position relating to the viewpoint is detected as being in the prescribed region, the processor executes the display function on the captured image displayed by the at least one display.
