Abstract

A system which can automatically display either regular two dimensional images or three dimensional images: The system includes, a processor which executes a program, a display, eye glasses which have electronically controllable lenses, and a detector unit connected between the processing unit and the display. Prior to displaying a three dimensional image, the processor sends a signal to the display which represents a particular bar code. The bar code indicates if the following three dimensional images will be displayed in page flip mode or in an interlaced mode. The detector unit detects the bar code and activates the special glasses so that the lenses in the glasses are alternatively opened and closed as frames are displayed. At the end of the three dimensional presentation, the processor sends another bar code to the display. The detector detects this bar code and the systems resumes normal two dimensional operation with both lenses in the glasses being open at all times. The present system can display a three dimensional "widow" on a screen which has normal two dimensional data. The three dimensional window is surrounded by a border which is detected by the detector unit and on…
