Yahoo: Tessera announced OptiML UFL technology, now avaliable for licensing. It's claimed to improve low-light performance of a camera module by increasing the amount of available light by as much as 250%, without degrading the field depth or other performance factors.
OptiML UFL uses a combination of advanced lens design and embedded processing technology. It has a unique fast lens design, which enables an F number that is significantly lower than a standard lens, without sacrificing the camera module’s close-range focus capability. This greatly improves indoor image capture where low-light situations generally occur.
From the PR it looks like OptiML UFL is based on Tessera EDoF technology, but the depth of focus enhancement is traded for an increased F number.
