Parameters and commands
•
Send the following serial command to record and apply new correction
data. The camera answers with a new prompt sign if the command has suc-
cessfully completed. The execution lasts for the duration of some images.
>C=1[CR]
>
Use the command
C=3
to re-enable the FPN correction without acquiring
new correction data. Instead, the correction data acquired by the last
C=1
call will be used. However, correction data is not stored beyond power loss.
Double region of interest mode (D)
In double ROI mode (
D=1
) the camera outputs two equally sized regions of
interest. Both ROIs share the parameters
N
and
I
and are output as two halves
of one image. The top half contains the lines of the primary ROI (ROI1), the bot-
tom half the lines of the secondary ROI (ROI2) accordingly.
The starting line address for ROI1 is configured using the parameter
A
.
Parameter
B
controls the starting line address of ROI2. Each ROI has the height
of (N + 1) lines, the resulting image has (N + 1) * 2 lines.
Parameter
D
also has an influence on the number of frames per second possible.
Use the following formula to calculate the exact number:
•
Max fps = 1 / ((D + 1) * (N + 1) + 1 + IOD) * t
L
);
he parameters are explained in the table below
Note
The correction data is volatile. So this command should be exe-
cuted at least once after switching-on for best performance.

IOD
IOD=0 if Continuous mode (e.g.
M=0
),

t
L
= 3 μs in single CL channel mode (e.g.
S=0
),
t
L
= 1.5 μsin dual CL channel mode (e.g.
S=1
)
