A display control device comprising: an image acquisition unit that is provided to a vehicle and is configured to acquire a display target image that is at least one of a front image acquired from a front image capture unit that is configured to capture a region including a front of the vehicle and a rear image acquired from a rear image capture unit that is configured to capture a region including a rear of the vehicle; a projection plane acquisition unit configured to acquire a three-dimensional virtual projection plane(Sp) to which the display target image is projectable, the three-dimensional virtual projection plane(Sp) including at least a side surface that rises in a height direction from a ground contact surface(Gr) of the vehicle; a correction unit that is configured, in a case where the display target image acquired by the image acquisition unit is projected on the virtual projection plane(Sp), to correct a projection position of the display target image to a second direction, which is from a first coordinate corresponding to a position where the virtual projection plane(Sp) intersects with a first virtual straight line extending in a first direction corresponding to a vehicle length direction of the vehicle from the front image capture unit or the rear image capture unit that is configured to capture the display target image to a second coordinate corresponding to a position where the virtual projection plane(Sp) intersects with a virtual reference line extending in the first direction that is apart from the first virtual straight line in a vehicle width direction of the vehicle; and an image synthesis unit configured to project the display target image on a corrected projection position, and to generate a three-dimensional image, characterized in that the correction unit is configured to acquire a correction ratio for correcting the projection position to the second direction on the basis of a first distance(ΔX) in the second direction between the second coordinate and a fourth coordinate where the virtual projection plane(Sp) intersects with a second virtual straight line connecting between a process target image capture unit that is configured to capture the display target image and a third coordinate where the virtual reference line intersects with a virtual reference plane(Rp) set at a predetermined distance from the process target image capture unit in the first direction, and a second distance in the second direction between the first virtual straight line and the virtual reference line, and wherein the virtual reference line extends in the first direction along a left side surface or a right side surface of a vehicle body of the vehicle. an image acquisition unit that is provided to a vehicle and is configured to acquire a display target image that is at least one of a front image acquired from a front image capture unit that is configured to capture a region including a front of the vehicle and a rear image acquired from a rear image capture unit that is configured to capture a region including a rear of the vehicle;
