US Patent 7911485 Method and apparatus for visual display calibration system

The present disclosure provides methods and apparatuses for calibration of a visual display. In one exemplary implementation of the invention, a visual display module is placed in a test station and a digital camera captures image data from the module. The digital camera can include a CCD digital camera and a lens for imaging. The captured image data is sent to an interface that compiles the data. The interface then calculates correction factors for the image data that may be used to achieve target color and brightness values for the image data. The interface then uploads the correction factors back to the visual display module.
