Based in San Jose, Calif., DigitalOptics Corp., a wholly owned subsidiary of Tessera Technologies Inc., has licensed its Face Tracker technology to South Korea-based Cammsys Co. Ltd., a camera module maker focused on the mobile phone market. The technology enables cameras to automatically adjust focus, color and exposure settings, optimizing portraits even in challenging conditions. Using face-oriented algorithms, the technology instantly detects faces in a camera viewfinder and tracks them moving through the image if the camera is rotated or subjects shift their poses.
