Abstract
A display for medical diagnostic equipment produces an image of the subject under study and a histogram image which indicates the distribution of brightness levels of the image pixels. Using a trackball, the operator manipulates a contrast window which is displayed on the histogram and which enables the operator to select brightness ranges in the image for contrast enhancement.
