Methods and systems for evaluating an imager that produces bi-chrome images from a scanner or a digital imaging device. The bi-chrome images have pixels of a first and second color. A method of evaluating an imager includes generating an image with a hand-held imaging device, the image having pixels of a first color and a second color. The image is analyzed to determine information about particles of the first and second color contained in the image. Each particle comprises contiguous pixels of the same color. The particle information is information on particle size and count of particles of the first and second colors. The image is determined to be acceptable or unacceptable based on predetermined objective criteria and the particle information. |
