Claim 7:
8. A non-transitory computer readable recording medium recording a display program executable by a computer to perform processing, the processing comprising:
detecting a target ahead of a vehicle;
setting an apparent angle of a marker relative to a reference plane in accordance with a distance between the target and the vehicle, the reference plane being related to a road surface on which the vehicle is traveling;
displaying the marker so as to be superimposed on the target as viewed by a driver of the vehicle;
setting the reference plane to the road surface;
setting the apparent angle to an index angle having a magnitude that is no larger than a right angle, the index angle being an angle between the marker and the road surface;
decreasing the index angle in conjunction with a decrease in the distance between the vehicle and the target;
increasing the index angle in conjunction with an increase in the distance between the vehicle and the target;
setting the index angle to a right angle in response to the distance between the vehicle and the target being at least a predetermined distance;
changing a size of the marker in accordance with the distance between the vehicle and the target; and
setting the size of the marker to be constant relative to the target.
