Abstract

The device is provided with an image acquisition unit for acquiring a peripheral image of a vehicle, the peripheral image being captured by an image pickup device provided to the vehicle; a display device for displaying the peripheral image, the display device being provided inside a vehicle cabin; and an indicator line output unit for causing an indicator line as a guide for a driver during a driving operation to be displayed superimposed on the peripheral image, at least one of a shadow portion and a side surface portion adjacent to the indicator line being added to the indicator line.

Claims

1. A vehicle peripheral display device comprising:

an image acquisition unit for acquiring a peripheral image of a vehicle, the peripheral image being captured by an

image pickup device provided to the vehicle;

a display device for displaying the peripheral image, the display device being provided inside a vehicle cabin; and

an indicator line output unit for causing an indicator line serving as a guide for a driver during a driving operation to be displayed superimposed on the peripheral image, a side surface portion on the side of the indicator line close to the image pickup device being added to the indicator line,

wherein the indicator line output unit displays the side surface portion so that the indicator line appears to float over a road surface in the peripheral image.

2. The vehicle peripheral display device according to claim 1,

wherein the indicator line includes a predicted trajectory line which extends in the direction of travel of the vehicle and indicates the predicted trajectory of movement of the vehicle in accordance with a steering angle, and

the indicator line output unit causes the predicted trajectory line to be displayed superimposed on the peripheral image.

3. The vehicle peripheral display device according to claim 1,

wherein the indicator line includes an extension from the vehicle width, extending in the direction of travel of the vehicle, and

the indicator line output unit causes the extension to be displayed superimposed on the peripheral image.

4. The vehicle peripheral display device according to claim 1,

wherein the indicator line includes a distance reference line used as a reference of forward distance from a front end of the vehicle or rearward distance from a rear end of the vehicle, and

the indicator line output unit causes the distance reference to be displayed superimposed on the peripheral image.

5. The vehicle peripheral display device according to claim 1,

wherein the indicator line includes a parking frame line for indicating a parking space, and

the indicator line output unit causes the parking frame line to be displayed superimposed on the peripheral image.

6. The vehicle peripheral display device according to claim 1,

wherein the indicator line output unit adds and displays a shadow portion adjacent to the side surface portion.

7. The vehicle peripheral display device according to claim 1,

wherein the peripheral image has three-dimensional depth and the indicator line output unit displays the side surface portion so that the indicator line is displayed in three dimensional fashion by the side surface portion over a road surface in the peripheral image.

8. The vehicle peripheral display device according to claim 1,

wherein the indicator line is a broken line.

9. The vehicle peripheral display device according to claim 1,

wherein the indicator line is intermittently arranged and drawn as an indicator having an arbitrary shape.

10. The vehicle peripheral display device according to claim 1,

wherein the indicator line output unit displays the indicator line and the side surface portion or shadow portion added to the indicator line so as to have a smaller width the greater the distance is from the image pickup device.
