Setting White Balance
(3)
(1) [Auto]
The white balance is adjusted automatically.
(2) [Light Source]
Select the light source from the pull-down menu below
according to the condition in which the camera is
used.
For an explanation on each item set in [Light Source],
see [White Balance] in the Setting page (p. 43).
(3) [Manual]
The white balance is adjusted manually.
[One-shot WB]
This is used for forcibly locking the white balance to
match the light source.
Example of setting method:
Illuminate a white subject (white paper, etc.) using
the light source, making sure the subject fills the
entire screen, and then execute [One-shot WB].
[R Gain], [B Gain]
When setting the white balance manually, set the
values of red and blue gain in the range 0 to 1023 to
match the light source.
Performing Operations and Settings in the Admin Viewer
Important
• Since the light source selection options are based on
representative characteristics, proper colors may not be
(1) achieved depending on the applicable light source. In this
case, use the [One-shot WB] function.
• If the subject looks greenish under mercury lamps in the
(2)
[Auto] mode, select the [Mercury Lamp] mode under light
source. If the video is still not shown in appropriate colors
under mercury lamps when the [Mercury Lamp] mode is
selected under light source, use [One-shot WB].
• When the subject has only one color, illumination is low, or
when sodium lamps, mercury lamps and certain other
fluorescent lighting are used, colors may not be adjusted
appropriately.
• When [Day/Night] is set to [Night Mode] (including when it is
set to [Auto] and night mode is judged to be applicable), the
white balance function cannot be used.
• Notes on capturing video continuously day and night
If a subject that seldom changes is captured in a location
where the light source changes gradually, such as when
capturing a subject continuously day and night, appropriate
colors may not be achieved.
In the above case, applying changes to the video to capture
will achieve the appropriate colors.
Setting the Day/Night Mode
(1) [Auto]
The camera automatically switches to day mode or
night mode depending on ambient brightness.
(2) [Day Mode]
Color video can be viewed in the normal mode.
(3) [Night Mode]
Video is shown in black and white.
Important
If the viewer is exited in [Day Mode] or [Night Mode], auto day/
night stays disabled even if [Auto] is set in the setting page. To
set auto day/night to enable, be sure to exit the viewer after
setting [Auto].
Note
Though the camera has an infrared filter, there is no effect on
lighting due to infrared light as the camera does not have an
insertion/removal mechanism for the filter.
