The present invention relates to a head mount system for providing a surgery support image, the system including: a head mount body wearable on a user's head; a near-infrared camera installed on the head mount body and capturing near-infrared light; a near-infrared image projection unit installed on the head mount body and projecting a near-infrared image; a near-infrared image processing unit receiving a captured image taken by the near-infrared camera, generating the near-infrared image, and transmitting the near-infrared image to the near-infrared image projection unit; and a transparent optic system installed on the head mount body to be positioned in front of user's eyes when the head mount body is worn on the user's head, transmitting visible light to enable a user to see a user's front, reflecting the near-infrared light coming from the user's front to the near-infrared camera to allow the near-infrared camera to capture the near-infrared light.
