Synthetic 3D Photo Frame

Almost all stereoscopic displays – such as 3DTVs – share one limitation. Even though you can see which objects are closer to you in the image than others, you still can’t peek around them to see what’s behind. To do this requires that the display support “motion parallax”, which means that the views change when you move your head. There are some volumetric and holographic displays that can do this, but your typical stereoscopic display only has one image available for each eye.

That’s not the case with the 3D LCD photo frame shown by Newsight Japan at SID 2010. You can start with a two-view stereoscopic image (in MPO data format), or even with just a 2D single view from a standard digital camera (in JPEG format). The image is then processed by a program on a PC that extracts the depth information from the image data. Using this information, it creates a total of five separate images. You can then display the processed image on the photo frame. The lenticular lens design makes it auto-stereoscopic, so no special glasses are required. And when you move your head to one side or another, you can “see around” objects in the front of the image and see what’s behind them.

The next generation of the photo frame will have the conversion software contained in the controller, so that it can automatically convert original 2D and 3D images. And a third generation model is planned with telecommunications features so that the panel can send and receive images from other panels. --Alfred Poor,
