an operation of displaying, on the display device, an image obtained by superimposing a distance guidance line indicating a position away from the vehicle by a predetermined distance and an auxiliary line to be added along the distance guidance line and having an appearance different from the distance guidance line, on the image of the vehicle surroundings; and

an operation of changing a mode of combination of the distance guidance line and the auxiliary line in at least one position, wherein

the distance guidance line is displayed in a plurality of positions with different distances from the vehicle, and the mode of combination of the distance guidance line and the auxiliary line is changed along positions having an equal distance from one of the left side or the right side of the vehicle on the plurality of distance guidance lines, and

positions having an equal distance from the one of the left side or the right side of the vehicle on the plurality of distance guidance lines are aligned in a vanishing point direction.

2. The display control device according to claim 1 ,

wherein the positions of changing the mode of combination of the distance guidance line and the auxiliary line are five or less positions.

3. The display control device according to claim 1 ,

wherein the operation further includes operation of adding the auxiliary line to overlap an upper side or a lower side or both sides of the distance guidance line and not adding the auxiliary line in a position where the mode of combination of the distance guidance line and the auxiliary line is to be changed.

4. The display control device according to claim 1 ,

wherein the operation further includes operation of adding the auxiliary line to a position coming in contact with an upper side or a lower side or both sides of the distance guidance line or to a position parallel to the distance guidance line at a predetermined interval and not adding the auxiliary line in the position where the mode of combination of the distance guidance line and the auxiliary line is to be changed.

5. The display control device according to claim 1 ,

wherein the operation further includes an operation of adding the auxiliary line to run along an upper side or a lower side or both sides of the distance guidance line and interrupting both the distance guidance line and the auxiliary line in a position where the mode of combination of the distance guidance line and the auxiliary line is to be changed.

6. The display control device according to claim 1 ,

wherein the operation further includes an operation of adding the auxiliary line to run along an upper side or a lower side or both sides of the distance guidance line and vertically interchanging the distance guidance line and the auxiliary line in a position where the mode of combination of the distance guidance line and the auxiliary line is to be changed.

7. A vehicle surroundings display system comprising:

an imaging device structured to image surroundings of a vehicle, the vehicle having a front end, a rear end, a left side and a right side;

a display control device structured to generate a display image having a distance guidance line indicating a position away from the vehicle by a predetermined distance and an auxiliary line to be added along the distance guidance line and having an appearance different from the distance guidance line superimposed on the image of the surroundings of the vehicle captured by the imaging device; and

a display device structured to display the display image generated by the display control device,

wherein the display control device includes:

a memory structured to store a plurality of instructions; and

a processor structured to operate as follows when the processor executes the plurality of instructions stored in the memory, and

the operation includes an operation of generating a display image in which a mode of combination of the distance guidance line and the auxiliary line is changed in at least one position, wherein

the distance guidance line is displayed in a plurality of positions with different distances from the vehicle, and the mode of combination of the distance guidance line and the auxiliary line is changed along positions having an equal distance from one of the left side or the right side of the vehicle on the plurality of distance guidance lines, and

positions having an equal distance from the one of the left side or the right side of the vehicle on the plurality of distance guidance lines are aligned in a vanishing point direction.

8. A display control device that controls to display an image of surroundings of a vehicle on a display device, the vehicle having a front end, a rear end, a left side and a right side, the display control device comprising:

an image processor structured to superimpose a distance guidance line indicating a position away from the vehicle by a predetermined distance and an auxiliary line to be added along the distance guidance line and having an appearance different from the distance guidance line, on the image of the vehicle surroundings,

wherein a mode of combination of the distance guidance line and the auxiliary line is changed in at least one position,

the distance guidance line is displayed in a plurality of positions with different distances from the vehicle, and the mode of combination of the distance guidance line and the auxiliary line is changed along positions having an equal distance from one of the left side or the right side of the vehicle on the plurality of distance guidance lines, and

positions having an equal distance from the one of the left side or the right side of the vehicle on the plurality of distance guidance lines are aligned in a vanishing point direction.
