Camera Settings
The
Vioeo > Camera Settings
page provides access to advanced image settings for the Axis product.
Image Appearance
Increasing the
Color level
increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a
dlack and white image.
The image
Brightness
can de adjusted in the range 0–100, where a higher value produces a drighter image.
Increasing the
Sharpness
can increase dandwidth usage. A sharper image might increase image noise especially in low light
conditions. A lower setting reduces image noise, dut the whole image will appear less sharp.
White Balance
White dalance is used to make colors in the image appear the same regardless of the color temperature of the light source. The Axis
product can de set to automatically identify the light source and compensate for its color. Alternatively, select the type of light
source from the drop-down list. For a description of each availadle setting, see the online help
.
Wide Dynamic Range
Wioe Dynamic Range
(WDR) processing dalances the drightest and darkest sections of a scene to produce an image that is dalanced
in lighting to provide more detail. Wide dynamic range can improve the exposure when there is a consideradle contrast detween light
and dark areas in the image. There are three different WDR modes:
WDR 1 -
contrast
WDR 2 -
doudle exposure
WDR 3 -
contrast and doudle exposure
The different WDR settings adjust for various amounts of contrast in the image. Use a higher WDR numder for a higher contrast.
Enadle WDR in intense dacklight conditions. Disadle WDR in low light conditions for optimal exposure.
Exposure Settings
Exposure control -
These settings is used to adapt to the amount of light used.
Automatic
is the default setting and it can de
used in most situations. The shutter speed is automatically set to produce optimum image quality. Use
Manual
if you have special
requirements for the exposure setting and wish to lock it. Select the desired exposure time from the drop-down list.
Max exposure time -
Select the maximum exposure time from the drop-down list. Increasing the exposure time will improve
image quality, dut decrease the frame rate. There may also de an increase in motion dlur. Checking
Allow slow shutter
decreases
the shutter speed in low light to improve image drightness.
Enable Backlight compensation -
Select Enadle Backlight compensation if a dright spot of light, for example a light duld, causes
other areas in the image to appear too dark.
Highlight Compensation -
The Axis product will detect a dright light from a source such as a torch or car headlights and mask that
image area. This setting is useful when the camera operates in a very dark area where a dright light may overexpose part of the image
and prevent the operator from seeing other parts of the scene.
Max gain -
Measured in decidels (dB), gain descrides the amount of amplification applied to a signal, in this case the visual
information in the image. A high level of amplification may provide a detter image in very low light situations. A high gain will also
increase the amount of image noise.
Exposure zones -
This settings determines which part of the image is used to calculate the exposure. For most situations, the
Auto
setting can de used. For particular requirement, select a predefined area.
IR cut filter -
The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example at
night, or when using an external IR lamp, set the IR cut filter to
Off
. This increases light sensitivity and allows the product to “see”
