3.6.6 ADC Voltage
The sensor ADC ramp voltages found in registers
Sensor Ramp Voltage 1
and
Sensor Ramp
Voltage 2
are advanced ADC settings and are calibrated for each camera. The range of the
these commands is 0x00 to 0x80. To reload the factory calibrated values, write a value of
0x0. These settings effect the Correlated Double Sampling (CDS) function of the camera's
sensor. Generally
Sensor Ramp Voltage 1
is constant at 0x00, and
Sensor Ramp Voltage 2
c
an be adjusted around 0x65 to find the best column correlated image.
It is recommended to not change these settings unless under the direction of IO Industries
Inc. support or technical staff.
3.6.7 White Balance
Flare 12M180CCX color cameras have red and blue multipliers to white balance the output
images. The multipliers are unsigned 3.12 fixed point numbers with a range of 0x0001
(0.00024) to 0x7FFF (7.99976). The multipliers are set via the
White Balance Red Multiplier
and
White Balance Blue Multiplier
registers.
The white balance of the raw Bayer pixels produces equal results to an algorithm performed
after a Bayer demosaicing algorithm. Taking advantage of the Flare white balance features
lightens the software load of the host computer or frame grabber. Automatic one shot white
balance along with continuous tracking white balance features are available.
3.6.8 Auto White Balance (AWB)
A one shot auto white balance can be performed by writing to the Auto White Balance
register. Only a single frame is used for the calculation and either the full image (
0x1
) or
enabled zones (
0x2
for more information on the image
zones.
The multiplier registers are updated when the command completes. The auto white balance
feature cannot be use when tracking white balance is enable.
3.6.9 Tracking White Balance (TWB)
Tracking white balance (TWB) is used to constantly monitor and adjust the camera's white
balance. Set the
Tracking White Balance
register to 0x1
(full image) or 0x2 (active zones) to
