A new design and image processing algorithm for lenticular lens displays

In this study, a new autostereoscopic 3D display design approach based on our patent specification is proposed and demonstrated. In contrast to common autostereoscopic two-viewdesigns with lenticulars, our approach allows more distance between image splitter and display panel. In comparison to 3D displays showing details at nominal distance, our design projects the images to a near zone in front of the display. As a consequence, the low magnification factor reduces distance errors from relative movements of display panel and image splitter. An image processing algorithm was developed to arrange the content and correct display shortcomings of image allocation caused by optical properties of the lenticulars. In addition, this algorithm allows static adjustment and tracking of observer position in a defined area in front of the display. We integrated the display in a production chain for digitalization and presentation of cultural heritage objects and developed special web-based modules for stereo rendering and user interaction, so that observers may explore cultural content in a natural manner.
