Patent number: 6400411Abstract: The invention overcomes the need to adjust the video level settings of different video capture devices for each source by saving each setting as a difference between the actual setting and a default setting when digitizing source material. These saved differences are called differential settings. An actual setting for another capture device that provides consistent video levels when digitizing the same source may be derived from both the differential setting obtained when digitizing using the first capture device and the default setting of the other capture device. As a result, source material is mapped to consistent internal digital levels when used on the different devices. Accordingly, video characteristics such as gain, black, saturation and hue can be maintained correctly regardless of the unique settings due to manufacturing and calibration tolerances of the different video capture devices.Type: GrantFiled: January 13, 1998Date of Patent: June 4, 2002Assignee: Avid Technology, Inc.Inventors: Stephen A. Bayes, Donald E. Nelsen
