Returning Video Information
The camera’s microcontroller has the ability to read video data w hen operating the
cam era in TDI Mod e. This fu nctionality can be u sed to verify cam era op eration and to
p erform basic testing w ithou t having to connect the cam era to a fram e grabber. This
inform ation is also u sed for collecting line statistics for calibrating the cam era.
Returning a Single Line of Video
Pu rp ose:
Retu rns a com p lete line of vid eo (w ithou t p ixel coefficients or test

the m inim u m , m axim u m , and m ean valu e of the line sam p led
w ithin the region of interest (the region of interest com m and is
exp lained in section Setting a Region of Interest).
