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 low light
conditions. ON option is advised to be selected for dark environment conditions,
and regulates the longest time for exposure to 4 seconds.
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.
NOTE
Setting the high limit value of slow shutter other than to 1x automatically increases
the camera sensitivity as the object becomes dark. When the sensitivity is high,
the exposure time becomes longer. Blurred images sometimes are prominent with
moving objects.
● Backlight Compensation
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.
(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."
LOW: high sharpness setting
MIDDLE: Standard setting
HIGH: low sharpness setting
