Webcam manufacturers routinely measure the image quality of their video by referring to the megapixel count of the sensor. Logitech has responded to this by developing the QuickCam Ultra Vision camera, which the company says has twice the optical clarity of other webcams. This is achieved by expanding the typically small lens of most webcams to a large 11.1mm (0.44 inches), preventing chromatic aberration and other problems associated with small glass elements. Logitech's 1.3-megapixel design also includes automatic light and sound adjustment that keeps the subject properly lit and eliminates background audio interference. Though its release date has not been announced, the QuickCam Ultra vision will ship for $130 when it becomes available.
