摘要： An HMD is provided with two piezoelectric vibrating gyros which detect vertical and horizontal angular velocities, and a horizontal sensor which detects a vertical angle. While the user's head rotates, shooting direction of a three-dimensional camera is varied in accordance with the angles obtained by integration of the detected angular velocities. While the head is stationary, the obtained vertical angle and the output of the gyro is corrected based on the angle detected by the horizontal sensor. The shooting direction of the camera can be manually set irrespective of the direction of the head, and information on the viewing direction is displayed together with a taken image.

摘要： In a reflective LCD, a liquid crystal element has a back surface reflection light reducer. The back surface reflection light reducer may be a back surface reflection prevention coating provided on the air-side surface of a liquid crystal sealing base member as a second base member, or may be an inclined surface which is the air-side surface of the second base member inclined relative to the reflective surface of the LCD. When the back surface reflection light reducer is a back surface reflection prevention coating, the image light emerging from white-displaying pixels is hardly reflected on a back surface in the liquid crystal sealing base member, is extracted through the liquid crystal sealing base member to the air side, and is directed through an observation optical system to the optical pupil. Thus, even with a construction in which image light emerging in an oblique direction from the reflective surface of the reflective LCD is directed through an axis-asymmetric observation optical system to an observer's eye, it is possible to prevent a lowering in the contrast of the displayed image due to back surface reflection.
