Description

  The present invention relates to a three-dimensional viewer. In particular, the present invention relates to a simple three-dimensional viewer using a mobile terminal such as a smartphone.

Humans recognize objects as three-dimensional objects by looking at them with both eyes shifted left and right, recognizing perspective in the head from the parallax of the left and right eyes, and simultaneously connecting them with a plane. It recognizes as creating a stereoscopic image.
Therefore, if one object is photographed with two cameras separated by a certain distance, and each of them is displayed separately in the left and right eyes, the images seen with both eyes can be perceived and synthesized simultaneously in the brain. Can be recognized three-dimensionally.
A viewer for stereoscopically viewing an image using this principle has been proposed.

  For example, in Patent Document 1, a video observation apparatus including a lens unit arranged corresponding to the left and right eyes, a pedestal unit on which an information processing terminal is placed, and a connecting unit that fixes the positional relationship between the lenses. Therefore, it is a device that can be placed on a desk or the like for stable observation.

  This device is easy to observe, such as adjusting the position of the lens and the pedestal. However, for the general public, the device is complicated, it is difficult to assemble the device, it is difficult to view and use the 3D viewer immediately after obtaining it, and it is bulky and difficult to mail by cheap mail. There was a problem.
