When the CCD converts the original image to electrical signals, the contrast
is reduced due to the influence that adjacent white and black pixels have on
one another as a result of lens properties. Typically, you will see very narrow
width and spacing between black and white areas. MTF corrects this
problem and emphasizes image detail.
