A4.2 Returning Video Information<br />
The camera’s microcontroller has the ability to read video data. This functionality can be<br />
used to verify camera operation and to perform basic testing without having to connect<br />
the camera to a frame grabber. This information is also used for collecting line statistics<br />
for calibrating the camera.<br />
Returning a Single <strong>Line</strong> of Video<br />
Purpose:<br />
Syntax:<br />
Syntax Elements:<br />
Returns a complete line of video (without pixel coefficients<br />
applied) displaying one pixel value after another. After pixel<br />
values have been displayed it also displays the minimum,<br />
maximum, and mean value of the line sampled within the region<br />
of interest (the region of interest command is explained in section<br />
294HA2.1 Setting a Region of Interest (ROI)).<br />
Use the gl command, or the following 110Hgla command, to ensure<br />
the proper video input range into the processing chain before<br />
executing any pixel calibration commands.<br />
gl x1 x2<br />
x1<br />
x2<br />
Pixel start number. Must be less than the pixel end number in<br />
a range from 1 to sensor resolution.<br />
Pixel end number. Must be greater than the pixel start number<br />
in a range from 2 to sensor resolution.<br />
Notes: • If x2 ≤ x1 then x2 is forced to be x1.<br />
• Values returned are in 12-bit DN.<br />

Returning Averaged <strong>Line</strong>s of Video<br />
Setting the Number of <strong>Line</strong>s to Sample<br />
Purpose:<br />
Sets the number of lines to sample when using the gla command<br />
or when performing FPN and PRNU calibration.<br />
Syntax:<br />
css m<br />
Syntax Elements:<br />
m<br />
Number of lines to sample. Allowable values are 256, 512,<br />
or 1024 (factory setting).<br />
Notes: • To return the current setting, use the 112Hgcp command or 113Hget<br />
css.<br />
