In manual mode (no check mark in the Auto checkbox) you can control the gain and shutter 
speed settings manually. The manual exposure mode disables the controls for contrast and 
backlight compensation in the other property tab (marked Image Controls) and the flickerless 
control in this tab. 

 

Defaults 

 

If you like a particular setting for particular lighting conditions, you can use the Save and Restore 
buttons to save and restore this preferred setting. Should you wish to restore all standard 
settings, then click on the Restore button under Factory. 

 

Performance icon 

 

The Performance text box on the 'Image Controls' tab is used to inform the user about camera 
settings, problems or special circumstances. Important messages will show a flashing icon. The 
same icon also appears in the 'Camera Controls' tab to indicate that an important message is 
being displayed in the Performance text box on the 'Image Controls' tab. 

 

Flickerless 

 

The Flickerless option should only be used under flickering 50/60 Hz light conditions (e.g. 
fluorescent or neon lamps) to prevent flickering or strangely coloured video images. If this option 
is used under normal lighting conditions the video image will tend to be overexposed. Note that 
the flickerless control is only available when the Auto Exposure setting is enabled on this tab. 
Please indicate under Mains whether your mains power frequency is 50 Hz (Europe) or 60 Hz 
(USA) so that the Flickerless control will work correctly.
