(C) Fine-tune the Image: Brightness/Contrast/Saturation/Hue
Not only clarity but also brightness, contrast, saturation and hue are essential factors to make
images closer to real scene
.
For cameras that support these configurations, you may
directly modify them and save via ENR interface.
After selecting a camera, click “
Video Adjustment
”
window, the fields available for
modification (depends on models) will be enabled. Select the desired value for the field, and
click “
Apply
”.
Field Name
Description
Brightness
(1-100)
Defines how much portion of light and of dark appear in the image. As the value
increases, the image appears brighter, and vice versa.
Contrast
(1-100)
Defines the range level between light values and dark values. As the value
increases, the separation between light and dark becomes more obvious.
Saturation
(1-100)
Defines the level of the actual color intensity. As it increases, colors appear
more pure; as it decreases, colors appear more gray-out.
Hue(1-100)
It is the term used to refer to the pure spectrum colors. Adjust this value to find
the color closest to the real scene.
Line
Frequency
(50Hz / 60 Hz)
The function that adjusts the shutter speed options to match the frequencies of
artificial light source of given country. For example, in Europe, the light
frequency is 50Hz (due to power supply frequency of lights), that is 50 flashes
per second. By setting line frequency to 50Hz in such case, the shutter speed
options will be proportional with light source frequency, such as 1/25s, 1/50s,
1/100s, etc. It is necessary to have the camera’s line frequency adjusted
according to the power frequency of the light source to avoid flickering effect.
