Description

  The present invention relates to a video observation apparatus for viewing a stereoscopic video displayed on a display unit of an information processing terminal.

  2. Description of the Related Art Conventionally, a technique for realizing stereoscopic vision by separately providing a left-eye image and a right-eye image, which are two-dimensional images with parallax in the left and right eyes of an observer, is known. As a method of providing the left-eye video only to the left eye and providing the right-eye video only to the right eye, for example, the left-eye video and the right-eye video are alternately displayed and synchronized with this alternate display. There is a shutter system that opens and closes the left and right shutters of the glasses worn by the observer. Further, for example, there is a polarization method in which the polarization direction of the left-eye image and the right-eye image is made different so that only one image is transmitted by the polarization filter of the glasses worn by the observer. Furthermore, there is a method using an apparatus including an optical system that provides an image independently to the left and right eyes of an observer, such as HMD (Head Mounted Display) (for example, Patent Document 1).
