increases when Auto Gain Control is near maximum. Lighting is recommended to
obtain good image quality.
NOTE
If sensitivity is still short after setting Auto Gain control, set the high limit value of
the slow shutter and Day/Night function, to further increase sensitivity.
•
Shutter speed
It is a parameter that determines the exposure time. It shows the length of time the
exposure is open or the amount of light that reaches the image sensor. The lighter
the environment is, the less shutter speed should be.
•
Slow shutter
It is a special function for obtaining a good quality color image in the poor light
conditions. ON option is advised to be selected for dark environment conditions,
and regulate the longest time for exposure to 4 seconds.
NOTE
Setting the high limit value of slow shutter other than to 1x automatically
increases the camera sensitivity to the set high limit value as the object becomes
dark.
•
Black Compression
Set an area for backlight compensation. Backlight compensation is a function that
achieves the brightness of a selected area to an optimum image level. This
function is effective when the auto aperture lens tends to close due to an intense
light that enters in areas other than those wished to view so that areas desired to
see become dark and difficult to see. In this case, set the area so that the portion
wished to see enters the selected area. The area size is roughly as follows.
1. OFF 2. Upper 2/3 (Area designation) 3. Lower 2/3 (Area designation)
4. Center 1/3 5. Center 1/6 (Area designation) 6. Left or Right (Area designation) 7. Auto (Area designation)
(The image level of shaded parts is maintained appropriate)
When OFF, rear light correction is not performed.
● Sharpness
Set a sharpness effect. The sharpness effect increases in the order of "LOW"
"MIDDLE," and "HIGH."
HIGH: Activates sharpness strong.
MIDDLE: Standard setting
LOW: Activates sharpness weak.
NOTE
Setting to "LOW" or "HIGH" increases the sharpness effect. After images,
however, sometimes become prominent when a moving object is photographed.
