„ Setting White Balance
(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. 52).
(3) [Lock]
The white balance is fixed to that of the video currently
received.
To forcibly fix the white balance according to the light
source, use [One-shot WB].
Example of Setting Method:
Irradiate a white subject (white paper, etc.) using the
light source and capture the subject over the entire
screen. In this condition, select [One-shot WB].
„ 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 image can be viewed in the normal mode.
(3) [Night Mode]
Images are shown in black and white, due to the
disabling of the infrared cut filter.
(4) [Day/Night Mode Focus Settings]
Click to display the [Day/Night Mode Focus Settings]
panel for making focus settings when switching Day/
Night Mode. Can only be set when [Focus] is set to
[Manual] (p. 139).
Important
• If the subject is a traffic signal or electronic scoreboard, etc.,
the captured image may flicker.
In this case, try changing [Exposure] to [Auto (Shutter-priority
AE)] and then select a shutter speed lower than 1/100, to see
if the situation improves.
• The [BLC] button is not available if [Exposure] is set to
[Manual].

Important
• Since the light source selection options are based on
representative characteristics, proper colors may not be
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
[Auto] mode, select the [Mercury Lamp] mode under light
source. If the image 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, under low light
conditions, or when sodium lamps, mercury lamps or certain
other fluorescent lighting is used, colors may not be adjusted
automatically.
• 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 image to capture
will achieve the appropriate colors.
