Design considerations for new 3D image display system with improved compatibility with invisibility and readability

This paper describes design considerations for acquiring improved performance on a new type of display system for regenerating three-dimensional images with an invisible high-frequency code pattern whose attribute depends on the depth of object. Three-dimensional images to be demonstrated on the new 3D image display system will be generated in the following 3 steps: That is; firstly embedding data of depth information into a 2D object image while taking it with a camera, secondly estimating true value of depth information embedded, and thirdly eliminating invisible pattern from an object image taken or diminishing contrast ratio depending on an estimated value of image depth. Here, we have to note that the diminished contrast implies reduced readability on an object image. With these three steps, improved compatibility with invisibility and readability on an invisible pattern was set up at optimum with an allowable margin.
