Abstract
A method and a computer readable medium containing instructions for devices marking pixel data as being critical symbology pixel data for verification prior to being displayed a pixel on a display device is presented. The method comprises determining by a computing device whether the pixel data is critical symbology pixel data and assigning an intensity threshold level to the pixel data. The threshold is based at least in part on the status of the pixel data as being critical symbology pixel data. Further, the method includes determining whether an intensity of the pixel data is less than or equal to the assigned intensity threshold level and then marking the pixel data as critical symbology pixel data when the intensity of the pixel data is greater than the intensity threshold.
