Abstract: A method is disclosed for providing a virtual image to a user in a Head-Mounted Display (HMD) device. The method includes detecting an ambient illumination, calculating a target transmissivity of window provided in the HMD device, based on the ambient illumination, adjusting a transmissivity of the window based on the calculated target transmissivity, and providing a virtual image to the user by projecting light to the window from a projector provided in the HMD device.
