3.7.2 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 th e cam era to a fram e grabber. This
inform ation is also u sed for collecting line statistics for calibrating the cam era.
