1. A virtual golf simulation device for simulating movement of a ball on a virtual golf course, the virtual golf simulation device comprising:
a memory configured to store a hardness value indicative of a degree of hardness of a terrain in the virtual golf course; and
an image processor configured to simulate a movement trajectory of a ball on the virtual golf course based on shot data on a user's golf shot and the hardness value,
wherein the image processor simulates the movement trajectory of the ball by adjusting a clamp range based on the hardness value and calculating an out-speed based on the adjusted clamp range.
