7.10 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
applied) 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
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
