Pupilometer for 3d display

The binocular distance recognition device for 3D display is disclosed. The apparatus, in the 3D image under the control of the standard binocular distance (criteria pupil distance) display unit, a control, and a view cone to control the view cone (view cone) that make up the 3D image and outputs the 3D image corresponding to the It includes parts of artifacts (artifact) a user input for receiving user feedback as to whether observed. Control unit, which can be moved within the margin (margin) corresponding to the view cone based on a bilateral distance, based on the user feedback, to change the reference distance, or both eyes, it is possible to determine the distance based on both eyes in binocular distance of the user.
