The camera provides settings to compensate for common lighting problems.
n
Auto Iris
allows the camera to compensate automatically for the light level.
n
Backlight Compensation
reduces contrast to adjust for bright light behind the main subject of the
shot. Use this if the subject is in front of a window, projector screen, or other bright area and appears as
a silhouette. This setting can't be used with Wide Dynamic Range.
n
Wide Dynamic Range
automatically darkens bright areas and brightens dark areas to provide a more
properly exposed image in challenging lighting conditions. This setting can't be used with Backlight
Compensation.
n
Point Light Compensation
reduces the intensity of small, extremely bright areas (point light sources)
that would otherwise swamp the camera with light and make it difficult to see details in areas with less
intense lighting.
Point Light Compensation is only available on the RoboSHOT 12E HDBT and
RoboSHOT 30E HDBT cameras. It is on the General tab of the System page.
Note
Wide Dynamic Range is not available on RoboSHOT 30 HDBT cameras, but it is available on the other
RoboSHOT HDBT cameras.

Fine-Tuning Image Quality and Color
C
AMERA PAGE
Fine-tune the color and lighting as needed using the Color Settings controls.
n
Auto White Balance
adjusts color automatically. Red gain and blue gain controls are not available
when Auto White Balance is selected.
n
Red Gain
and
Blue Gain
provide manual color adjustment.
n
Detail
adjusts the image sharpness. If the video looks grainy or “noisy,” try a lower Detail setting. (As in
conversation, too much detail is bad.)
n
Chroma
adjusts the color intensity.
n
Gamma
adjusts the range (grey density) between bright areas and shadows.
If you change Red Gain or Blue Gain and you don't like the results, start over by selecting and then
deselecting Auto White Balance.
