2.6.3 Image Viewer Setting
Users correct the values of Contrast, Brightness, and Gamma in order to acquire more clear
images before photo scanning.
Contrast: It adjusts the visibility by contrasting images. If you adjust Contrast value
rather than Brightness value, you can acquire more clear and bright images.
Brightness: It adjusts the brightness of images.
Gamma: You can adjust images more naturally by correcting gamma value that makes
bright part brighter and dark part darker.
Use this function when you cannot acquire clear images even if you adjusted the values
of Contrast and Brightness.
When specific parts of images are excessively bright, correct them, adjusting overall
balance by decreasing the contrast value and increasing brightness value and then
adjusting gamma value.
