Colour Adjustment Tab
The first three slider bars labelled:
R Gain
,
G Gain
and
B Gain
, can be used to
manually adjust the red, green and blue colour reproduction of the camera.
Alternatively, the camera can automatically set these values by pressing the
White
Balance
button. Automatic values may not be appropriate in certain circumstances
depending on the light conditions, luminosity of the target, etc. Other values that are
user selectable include
Gamma
and
Contrast
.
User defined settings can be stored for future use. There are four sets of parameters
that can be stored for future use. They are labelled
A
,
B
,
C
and
D
. Simply select one
of them and click the
Save
button.
Exposure Tab
When auto-exposure is used, the user
cannot specify the
Gain
value. It is not
user definable in auto-exposure mode.
The
Gain
value corresponds to the
camera’s on board electronic sub-system
that amplifies the sensitivity of the camera.
To set the exposure time manually, simply
un-tick the
Auto Exposure
option. In this
mode, the time can be set in milliseconds
and the
Gain
value can be set manually.
Setting the
Gain
value too highly may result in some image noise. Typically, the
light sensitivity of the camera increases much faster than the image noise as the
Gain
increases.
When the camera operates in manual exposure mode, the
Set Time
button must be
pressed in order to activate a new exposure time. Setting the exposure length using
the
Exposure Time
sliding bar on its own is not enough.
The camera’s frame speed can be set to
Normal
(better image quality) or
High
(higher frame rate).
