Configuring Image Settings
Slow Shutter: Available if Automatic Exposure is set to Manual.
Select from OFF, 1/30, 1/15, and 1/7.5. Enabled this feature if the
sensitivity is not good enough under "High" gain condition at dark.
Optimal image level can be maintained by appropriate gain and shutter
combination that determined automatically inside the unit system. Slow
Shutter can be selected as slow shutter activates, the exposure time
becomes longer and frame rate becomes smaller, and moving objects
may result in blurred images.
Manual Gain: Available if Automatic Exposure is set to Manual. The
value of Manual Gain can be set from 6 to 30dB as an increment of 6.
This function applies to manual lens only.
AGC Maximum: Available if Automatic Exposure is set to AES. As
an adaptive system found in many electronic devices, the average output
signal level is fed back to adjust the gain to an appropriate level for a
range of input signal levels.
Noise Reduction: Selectd a value from 0 to 5 to configure the noise
reduction related setting to manipulate noise on the screen. Noise
reduction is the process of removing noise from signal.
5. From the Image Color section, set the values for the following:
Brightness adjustment: Changing the brightness level allows you to
increase or decrease highlights and shadows, making them darker or
lighter. The values range from -255 to 255.
Contrast: Changing the contrast level allows you to increase or
decrease the difference between the lightest and darkest parts of the
image. The values range from 0 to 128.
Saturation: Changing the saturation level allows you to increase or
decrease the color intensity in the image. Saturation describes the
difference of a color from the gray of the same lightness. Increasing
saturation deepens the colors of your images, making reds redder and
blues bluer. The values range from 0 to 255.
Hue: Set picture hue from level -15 to 15.
AWB: Set the white balance values to correspond to the environment
condition for best color rendition. "ON": Automatically adjusted
according to ambient lighting condition. "OFF": Manually adjusted by
users. This is useful for some conditions where AWB may be insufficient
to perform correctly. You can set the current R/G/B/ color temperature
manually.
