IMAGE CAPTURING AND VIDEO OUTPUT
Read-out control 7.12
Exposure control is done by means of the Camera Control Exposure and Camera Control Frame
read-out.
Read-out control is done by means of the Camera Control Frame readout command. This is applicable
in the following modes:
Delayed transfer control mode •
Double delayed transfer control mode •
NOTE: In Normal control mode and in Double transfer control mode image readout always starts at the
end of exposure. There is no separate camera read-out trigger signal and the Camera Control Frame
readout command is therefore not applicable.
Additional to starting read-out with an external trigger signal, it is also possible to start readout upon
a ‘soft request’. This is a request done by a separate command. This possibility is programmed by
means of the same Camera Control Frame readout command.
