Camera modes of operation 113
In a variable line scan rate with variable frame size, the camera is set to transmit
video-on-demand, using internal or external exposure time control. The line rate
is a function of the line trigger; the frame capture is initiated by the frame trigger.
The frame size is a function of the frame trigger’s active level duration up to a
maximum of n lines, as defined in the DCF.
The required connections when using this mode are from the frame trigger signal
Y to the frame grabber as well as the line trigger signal to the frame grabber. The
exposure from the frame grabber to the camera. You also need to connect the
R synchronization signals from the camera to the frame grabber, or the frame grabber
PRE19LIMMAINYA2005 to the camera, and the video signal from the camera to the frame grabber.
