Returning Video Information
The camera’s microcontroller has the ability to read video data when operating the
camera in TDI Mode. This functionality can be used to verify camera operation and to
perform basic testing without having to connect the camera to a frame grabber. This
information is also used for collecting line statistics for calibrating the camera.
Returning a Single Line of Video
Purpose:
Returns a complete line of video (without pixel coefficients or test
pattern) displaying one pixel value after another. It also displays
the minimum, maximum, and mean value of the line sampled
within the region of interest (the region of interest command is
Use the
gl
command, or the following
gla
command, to ensure
the proper video input range into the processing chain before
executing any pixel calibration commands.
Syntax:
gl x1 x2
Syntax Elements:
x1
Column start number. Must be less than the column end
number in a range from
1
to (
column resolution – 1
).
x2
Column end number. Must be greater than the column start
number in a range from
2
to sensor resolution.
Notes:
•
If
x2
≤
x1
then
x2
is forced to be
x1
.
•
Digital offset, background subtract, and digital system gain
are applied to the data. FPN and PRNU coefficients are not
included in the data.
•
Values returned are in 12 bit DN.
•
Available in TDI Mode only.

Returning Averaged Lines of Video
Setting the Number of Lines to Sample
Purpose:

gla
command
or for pixel coefficient calculations.
Syntax:
css i
Syntax Elements:
i
Number of lines to sample. Allowable values are
1024,
2048, or 4096
