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 explained in
Setting a Region of Interest ).
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
.
• Analog gain, analog offset, digital offset, background subtract, and digital system
gain are applied to the data. FPN and PRNU coefficients are not included in the data.

(the region of interest command is explained in Setting a Region of Interest ).
