Vehicle peripheral display device

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 indicator lines serving as a guide for a driver during a driving operation to be displayed superimposed on the peripheral image,

wherein the indicator lines includes a pair of first indicator lines spaced apart from each other in a width direction of the vehicle and extending in a travel direction of the vehicle, and a pair of second indicator lines extending in a direction intersecting the pair of first indicator lines,

wherein side surface portions are added to the sides of the pair of second indicator lines close to the image pickup device for parking assist,

wherein the indicator line output unit adds and displays shadow portions adjacent to the side surface portions, and

wherein the shadow portions includes a pair of first shadow portions added to the sides of the pair of first indicator lines close to the image pickup device, and a pair of second shadow portions added to the side surface portions added to the pair of second indicator lines.

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

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

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

wherein the indicator lines are broken lines.

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

wherein the indicator lines are intermittently arranged and drawn as indicators having an arbitrary shape.

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

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

10. The vehicle peripheral display device according to claim 1 , wherein the control unit detects the parking operation in response to detecting a shift to a reverse operation of the vehicle.

11. The vehicle peripheral display device according to claim 1 , wherein the indicator line output unit displays the side surface portions so that the indicator lines appear to float over a road surface in the peripheral image.

12. The vehicle peripheral display device according to claim 1 , wherein a brightness of the side surface portions provided in the indicator lines for giving parking assist during a parking operation is set to be lower than a brightness of the indicator lines.
