Abstract
An artifact inducing image acquisition mapping system and technique is described for use in connection with digital imaging. A gray scale mapping technique is employed to indicate to an operator the brightness function of each pixel of an image. Where the brightness function is less than 95% of saturation, the image is displayed normally. Where the brightness function is at least equal to the saturation full scale value, that portion of the image is displayed in total black. Where the brightness function is between 95% and 100% of saturation full scale value, the image portion is displayed as mixed dark and light, i.e., a speckled region. An alternate embodiment simply displays saturated regions to total black.
