Exposure Mode
The
Exposure
Mode
allows you to configure the exposure settings to meet the image quality
requirements in relation to lighting and other considerations.
Auto Exposure Settings
Method:
Select which area of the image will be used to measure the amount of light to achieve
best exposure.
• Center Weighted:
Exposure metering is averaged over the entire frame but emphasis is
placed on the central area.
• Object Targeted:
This option meters the exposure based on the targets you specify. When
this option is selected, define your target by clicking squares displayed on the image and
then press
Save Spot Window
to save the setting.
EV:
In a scene with predominantly light or dark areas, the image will be underexposed or
overexposed, causing an image to be too dark or bright. In such situations, you can adjust a
compensation value to optimize the exposure. Decrease the value if images appear too light
(overexposed). Increase the value if images are too dark (underexposed).
Max/Min. Exp:
Select the maximum / minimum exposure time according to the light source. The
selectable value will change according to the frequency setting under
Image
>
Basic Settings
.
Sensitivity:
Select how sensitive the camera reacts to the light. A higher value enables the
camera to be more sensitive to the light conditions and adjust the exposure in the shortest time
interval.
Max Gain:
Specify the maximum amount of amplification applied to the image. A high level of
gain allows images to be viewable in very low light, but will increase the image noise.
Manual Exposure Settings
Exposure Time:
Enter a desired exposure time.
Gain:
Select a gain value from 0 to 16. A high level of gain allows images to be viewable in very
low light, but will increase image noise.
