Returning the Average of Multiple Lines of Video
Purpose:
Returns the average for multiple lines of video data (without pixel
coefficients or test pattern). The number of lines to sample is set
and adjusted by the
css
command. The camera displays the Min.,
Max., and Mean statistics for the pixels in the region of interest (the
region of interest command is explained in section
Syntax:
gla 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 column 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.

Temperature Measurement
The internal temperature of the camera can be determined by using the
vt
command.
This command will return the internal chip temperature in degrees Celsius. For proper
operation, this value should not exceed 75 °C.
Note:
If the camera’s internal temperature reaches 75 °C, the camera
will shutdown and
the LED will flash red
. If this occurs, the camera
must be rebooted
using the command,
or can be powered down manually. You will have to correct the temperature problem
or the camera will shutdown again.
IMPORTANT!
Refer to the camera mounting instructions below for more information on
managing the camera temperature.
Voltage Measurement
The command
vv
displays the camera’s input voltage. Note that the voltage
measurement feature of the camera provides only approximate results (typically within
10%). The measurement should not be used to set the applied voltage to the camera but
only used as a test to isolate gross problems with the supply voltage.
