AXIS P1346/-E/AXIS P1347/-E - Video & Audio
Wide Dynamic Range
Check the box Enable Dynamic Contrast to improve the exposure when there is a considerable contrast between light and
dark areas in an image.
Exposure Settings
Configure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth
considerations.
Exposure value - Click in the bar to fine-tune the exposure. Increasing the exposure will improve image quality at the
expense of the total frame rate. There may also be an increase in motion blur.
Exposure control - This setting is used to remove 50 or 60 Hz flicker caused by a fluorescent light source. The Hold current
option locks the current exposure settings.
Enable Backlight compensation - Backlight compensation makes the subject appear clearer when the image background is
too bright, or the subject is too dark.
Exposure zones - This setting determines which part of the image is used to calculate the exposure. For most situations, the
Auto settings can be used, but for particular requirements, select Defined and click Edit... to open the Exposure Windows
dialog where you can customize the exposure zone. See the online help for more information.
Exposure priority - This defines the balance between image quality and frame rate. Prioritizing Motion minimizes motion
blur but may result in reduced image quality with a higher frame rate. Selecting Low noise provides better image quality
with a lower frame rate. The Shutter and Gain settings can be used to further adjust the amount of motion blur and noise
in the image. See the online help for more information.
Enable automatic iris adjustment - Check this box to enable automatic iris adjustment. When enabled, the iris will
automatically be adjusted to compensate for changing light conditions. This option is not available if a fixed iris is used.
Iris adjustment - This option applies to P-Irises only. Use the slide bar to set the preferred f-number. The scale represents the
amount the iris is open. If set to 0, the iris is opened as much as possible. If set to 100, the iris is closed as much as possible.
The actual f-number is shown below the iris adjustment bar. If Enable automatic iris adjustment is checked, the iris will stay
at this position as long as light conditions are favorable. If light conditions change, the iris will adjust itself to the best iris
settings. If the box is unchecked, the iris will lock on the set position regardless of light conditions.
