  • Method of adjusting gray scale response to more closely correlate scanner based image analysis systems
    Patent number: 6934055
    Abstract: The present invention provides for a method of adjusting the gray scale response of a first scanner and a second scanner so that the two gray scale responses more closely match one another. The method includes the step of providing a first scanner that has a gray scale response upon scanning a target. Also, a second scanner is provided that has a gray scale response upon scanning the target that is adjustable. The gray scale response of the first scanner is measured upon the scanning of the target. Also, the gray scale response of the second scanner is measured upon scanning the target. Additionally, the gray scale response of the second scanner is adjusted in order to more closely match the gray scale response of the first scanner.
