## Abstract

The present disclosure provides a vehicle display control device including a processor and an image forming section configured to form an AR image having a shape that conforms to a dividing line of a lane in which a vehicle travels, using information from a sensor that recognizes the dividing line, wherein the processor is configured to control the image forming section so as to form the AR image, and determine a length, in an extension direction of the lane, of the AR image that the image forming section is caused to form, based on a reliability of a detection result of the sensor.

## Claims

### Claim 1

A vehicle display control device comprising:
a processor; and
an image forming section configured to form an AR image, having a shape that conforms to a dividing line of a lane in which a vehicle travels, using information from a sensor that recognizes the dividing line,
wherein the processor is configured to:
control the image forming section so as to form the AR image, and
determine a length, in an extension direction of the lane, of the AR image that the image forming section is caused to form, based on a reliability of a detection result of the sensor.

### Claim 2 (depends on 1)

The vehicle display control device according to claim 1, wherein the processor does not cause the image forming section to form the AR image, when the reliability is lower than a predetermined value.

### Claim 3 (depends on 1)

The vehicle display control device according to claim 1, wherein the lower the reliability is, the shorter the length of the AR image that the processor causes the image forming section to form is.

### Claim 4 (depends on 1)

The vehicle display control device according to claim 1, wherein the sensor is a camera, and the processor is further configured to recognize the dividing line only based on image data acquired by the camera.

### Claim 5 (depends on 4)

The vehicle display control device according to claim 4, wherein a characteristic amount of the image data is used to determine a level of the reliability of the detection result of the sensor.

### Claim 6 (depends on 5)

The vehicle display control device according to claim 5, wherein the processor is further configured to:
receive the image data acquired by the camera; and
upon determining that the image data includes the dividing line, determine the level of the reliability by referring to a reliability determination map that associates different levels of the reliability with corresponding characteristic amounts of the image data.

### Claim 7 (depends on 1)

The vehicle display control device according to claim 1, wherein the AR image is formed by the image forming section to have the determined length, and the formed AR image is displayed on a windshield of a vehicle.

### Claim 8

A vehicle display control method, comprising, by a processor:
causing an image forming section to form an AR image, having a shape that conforms to a dividing line of a lane in which a vehicle travels, using information from a sensor that recognizes the dividing line; and
determining a length, in an extension direction of the lane, of the AR image that the image forming section is caused to form, based on a reliability of a detection result of the sensor.

### Claim 9

A non-transitory recording medium storing a program executable by a computer to perform processing, the processing comprising:
causing an image forming section to form an AR image, having a shape that conforms to a dividing line of a lane in which a vehicle travels, using information from a sensor that recognizes the dividing line; and
determining a length, in an extension direction of the lane, of the AR image that the image forming section is caused to form, based on a reliability of a detection result of the sensor.
