5.6 Control of Contrast and Brightness
When you finish focus setting and you acquired images you want, ready for image
acquisition by controlling contrast and brightness.
5.6.1 Control of Contrast/Brightness
When you control the values of Contrast and Brightness, you can get clear images.
1) Contrast: Adjust the visibility by controlling image contrast. Controlling contrast value
rather than brightness value makes possible to get more clear and bright images.
2) Brightness: Adjust the brightness of images.
3) Gamma: By correcting Gamma value which makes bright part brighter and dark part
darker, you can control images more naturally. It is used when you cannot acquire clear
images even if you have controlled the values of contrast and brightness.
