Means and methods for correcting the loss of contrast caused by modulation transfer function (MTF) effects in imaging. Images of small objects are enhanced without adversely affecting large object images. A homogeneous background is provided and image contrast is obtained with total MTF effects. The scale of the determined image contrast is manipulated to cause the contrast to approximate an ideal contrast not affected by the MTF contrast reduction.
