Tessera Licenses OptiML Focus to AzureWave

Photonics.com
Mar 2010
SAN JOSE, Calif., March 25, 2010 – Tessera Technologies Inc. announced it has licensed its OptiML Focus image enhancement solution to AzureWave Technologies Inc. of Taiwan.

The solution, which provides automatic focus capabilities in camera-enabled devices to deliver high-quality images with no moving parts, will be integrated into the latter company’s next-generation camera modules for laptop computers, webcams, cell phones and other camera-enabled devices.

The OptiML Focus image enhancement solution enables all objects in an image to be in focus simultaneously, for the entire depth of field, with no mechanical parts. Providing an alternative to current autofocus solutions that require moving parts, the technology provides improved image quality when compared to current fixed focus solutions, according to the company. Additionally, it enables barcode and full document capture for fixed lens camera based solutions.

The former company received an initial fee from the latter company under the licensing agreement in the fourth quarter 2009.

GLOSSARY
camera
A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
depth of field
The distance, on either side of the object plane focused on, through which satisfactory image definition can be obtained. For the special case of an imaging system with lens axis perpindicular to the image plane, focused at a range of 25 ft, and with definition acceptable for objects from 20 to 40 ft; the depth of field extends from 5 feet in front of, to 15 feet behind, the object plane focused on.
focus
1. The focal point. 2. To adjust the eyepiece or objective of a telescope so that the image is clearly seen by the observer. 3. To adjust the camera lens, plate, or film holder so that the image is rendered distinct. 4. To move an entire microscope body tube relative to a specimen to obtain the sharpest possible image.
image enhancement
The digitization process by which an image is manipulated to increase the amount of information perceivable by the human eye.
lens
A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
