Abstract
A method for use with an identification card printing system to improve contrast of an original image represented by an array of pixels each having a pixel level representing an intensity of the pixel includes a first step of selecting a pixel of the pixel array. Next, an adjusted pixel level is calculated for the selected pixel based upon its pixel level and at least one proximal pixel level defined as the pixel level of a pixel located proximate to the selected pixel. Finally, the selecting and calculating steps are repeated for substantially all of the pixels of the pixel array to form an adjusted pixel array that represents an adjusted image having greater contrast than the original image.
