Abstract
The present disclosure provides methods and apparatuses for on-site calibration of a visual display sign. In one exemplary implementation of the invention, an imaging device captures image data from a visual display sign. The imaging device can include a CCD digital camera and optics for long-range 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 adjusted image data back to the visual display sign.
