There are few industry segments that are more competitive than the smartphone market. The market is not just competitive but it is also driven by technology speed and innovation. Most Smartphone OEMs have to balance cost, time to market (TTM) with product differentiation and innovation. The poLight technology offers a unique possibility to create innovation around one of the most critical features of a mobile phone, the camera functionality.
Some examples of unique use cases that the Tlens technology can bring. One is the now more or less classical selfie case where the user would like to take an image with focus on all persons and the background, in this case the ultra quick TLens® takes 3 images with different focus. These images are stitched together into one “All in Focus ” image, see illustration below.
Another use case is when the user would like to create an image with the traditional back camera and getting everything “in Focus”. The picture below illustrates such a case. The technology is the same, three or four images are created within a very short time and these images are stiched together into one image with everything in focus. Above illustrates one of several unique use cases that can be created by use of the TLens technology. There are several alternatives for the Smartphone OEMs to implement utilize the unque capabilites of the poLight products. These alterntives spans from adding a TLens on top of a fixed camera modula all the way to extensive design and application changes. poLight will here be a partner to support you in your design activities.
The video below illustrates the difference between the two technologies. On the left hand side, the advantages of the TLens® can be cleary seen, extremely quick focus and no “Field of View ” variation. The phone used is a mid-tier phone with the TLens® mounted on a fixed focus camera and with a contrast based auto-focus algorithm.
The right hand video shows a high-end smartphone with a VCM including PDAF. Please notice the significant lower speed and the some times inability to focus at all, as well as the “pumping effect” due to the use of VCM technology.
The video clearly illustrates the paramount advantages the new TLens® teachnology can bring to the camera experience in a smartphone.
What can the poLight technology bring to a multi camera device? The poLight technology and the first product launched, the TLens® Silver, is based on a polymer lens that can be tuned by a piezo element. The TLens® Silver provide extremely quick Focus functionality without the drawbacks of the VCM technology and the traditional VCM modules can simply be removed. The TLens® technology provides a range of capabilities such as extremely quick Auto Focus but also some unique capabilities in a multi-camera implementation:
The listed unique capabilities are not only applicable for dual camera cases but several of them removes the main drawbacks with dual camera technologies and allow OEMs to fully utilize the advantages. The two main drawbacks with dual or multiple camera configurations can be eliminated by use of the TLens® by:
