April 6, 2006 Faces are usually the most important part of any photo, so it makes sense to ensure that the face is captured to the best of the camera’s ability. That’s the reasoning behind the development of a new technology by imaging and connectivity solutions company FotoNation. Face Tracker for camera phones uses a radically new approach to identify and lock onto human faces in a camera phone’s preview image, tracking them as they move around within the frame and automatically adjusting focus, exposure, and white balance before the image is captured, ensuring that faces are optimally taken and that skin tones are reproduced with exceptional accuracy.

Especially important for shooting under poor lighting conditions and at night-time, Face Tracker draws a box around the face, showing the user which face is being tracked. It can also track multiple faces in the preview image simultaneously. Because of its advanced tracking algorithm, Face Tracker accurately follows and adjusts exposure on the selected faces as they move in frontal or profile positions and establishes the correct image orientation automatically.

FotoNation Face Tracker also takes into account any processing speed limitations within the camera phone. The Face Tracker technology is highly optimized, allowing sufficient processing power for the camera phone to run its own algorithms while faces are being detected, continuously maximizing the available resources.
