(2) Gray level change
To change the gray level, you can change the
"**.*TIMES" (magnification by N processing), the
"
γ
+," "
γ
-" (
γ
(positive/negative) correction), the
"CHNG-L" (widening histogram), and the "INCRS-
M" (mid emphasis) functions.

Mid emphasis
To improve the contrast (the ratio of high value gray levels to low value gray
levels), specify a magnification rate (00.0 to 99.9) for multiplying the image
data.
- If the magnified gray level exceeds 255, the system will correct the value
to 255.
Use to correct mid gray level.
- γ positive correction: used when the mid gray level is too low.

- γ negative correction: used when the mid gray level is too high.
This is a method to widen the histogram of an image in which the histogram
is at part of it, thus improve its contrast.
Emphasize the mid gray level.
- This improves contrast while remaining the background image.
- The input image density (G) can be converted to the output image density
with the following formulas:
