Notes: The digital offset is not reset.
3.5.2 Rebooting the Camera
The command
rc
reboots the camera. The camera starts up with the last saved settings
and the baud rate used before reboot. Previously saved pixel coefficients are also
restored.
3.6 Diagnostics
3.6.1 Generating a Test Pattern
Purpose: Generates a test pattern to aid in system debugging. The test
patterns are useful for verifying proper timing and connections
between the camera and the frame grabber. The following tables
show each available test pattern.
Syntax:
svm i
Syntax Elements:
i
0
Video.
1
12 bit ramp test pattern.
2
8 bit step test pattern.
Example:
svm 1
3.6.2 Returning Video Information
The camera’s microcontroller has the ability to read video data. 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. After pixel
values have been displayed 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 section
3.4.1 Setting a Region of Interest (ROI)).
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
