Abstract
A method is disclosed for automatic white balance correction of color cameras. The method includes capturing a first image of a target object, the first image containing a calibration area defined by a symbology and a calibration zone within the calibration area. The symbology encodes data and has first-color elements and second-color elements. The calibration zone is defined by at least some of at least one of the first-color elements and second-color elements. The method includes obtaining a location of the calibration area in the first image, and capturing a second image of the target object, the second image being multicolor. The method includes locating the calibration area in the second image based on the location, and analyzing the calibration zone within the calibration area of the second image. The method includes calculating and applying at least one white balance compensation bias based on the analyzed calibration zone.
