Chapter 3 Optics and Lighting White Balance Implementation White balance is a processing operation performed to ensure proper color fidelity in a captured digital image. The image sensor does not detect light exactly as the human eye does, and so some processing or correction of the detected image is necessary to ensure that the final image realistically represents the colors of the original image. Proper white balance is required to take into account the “color temperature” of the light source, which refers to the relative “coolness” of white light.
The main purpose of white balance as it relates to the Vision HAWK is to render neutral colors correctly (gray/white) and to provide consistent color results. Factory pre-set white balance calibration should be satisfactory for most applications, but the Vision HAWK allows for user adjustment or calibration of the white balance to account for exposure to different lighting conditions.
