3D VIDEO OBSERVATION DEVICE AND TRANSMITTANCE CONTROL METHOD

摘要

In this 3D video observation device (200), an optically transmissive HMD (208) displays a video observed when a 3D image in a virtual 3D space is projected in a real space. A transmittance alteration unit alters the transmittance of light passing through the optically transmissive HMD (208). A shutter control unit (220) sets the lower limit value for light transmittance to which it is possible for the transmittance alteration unit to alter.
