Problems solved by technology

The size of products is hard to reduce due to the restrictions of shapes of lens elements and material selection in conventional photographing modules, and it is also hard to keep a balance among molding of lens elements, assembling convenience and system sensitivity.
In the past, developments of interactive games or storages of images are mostly limited to two-dimensional space.
However, there are still certain differences among two-dimensional images and the real images seen by eyes.
