3.3.4 APERTURE
Sharpness is the subjective evaluation of detail in the picture. With this APERTURE
function, users can adjust the enhancement of the edges of objects in the picture.
When shooting text, this function may help to make it sharper and thus achieve a
better image. There are 32 adjustment levels; the options are <00> ~ <31>, where
<00> represents “no enhancement”.
• AUTO
The PTZ camera will assign an appropriate aperture value automatically to
enable the camera to capture a better image.
• MANUAL
Select this option if you want to adjust the aperture value manually. A higher
value enhances the incident light on the camera.
NOTE: On the 18
×/26× model, refer to section 3.3.9 SETUP MENU2 for
information about the aperture function.
