Exposure control:
• Exposure level: You can manually set the Exposure level, which ranges from -2.0 to +2.0 (dark to bright).
• Flickerless: This function helps avoid the flickering on images because of the fast shutter movement and
the inconsistency between power line frequency (50 or 60 Hz) and exposure time. When selected, the
exposure time will be forced to stay longer than 1/120 second. For KX-NTV150/KX-NTV160 that come with
fixed iris lens, setting the exposure time to longer than 1/120 second may introduce too much light into the
lens. Users can use this option to observe whether the result of long exposure time is satisfactory or not.
• Exposure time: you can split the round pointers on the Exposure time and Gain control slide bars into two
halves and drag them on the bars to designate a range of values in which firmware can automatically adapt
to. Note that Firmware will then automatically tune the Gain, Exposure time, and Iris opening within the
ranges you specified. For example, in low-light condition, you may prefer a longer exposure time and more
electronic gains. However, the noises in the image will also increase.
• Gain control: Tune the slider bar to set the Gain control to the best image quality. Higher gain control
value will generate a certain amount of noises, and that the gain control, lighting levels, and picture
performance is closely related.
