internally to form a frame.
Figure 5-11show how
N
lines are grouped into a frame, the start of the frame and the
capturing of the lines is activated by the corresponding trigger.

5.3.1.1
Free running
This is the factory default mode. Lines(Frames) are captured at the maximum rate possible.
It is limited by line(frame) period.
Factors which affects line(frame) period as mentioned in section 5.1.2
Factors affecting line(frame) period
Exposure time
Exposure time for each line
Acquisition frame time
The minimum time between 2 frames
(Default value: 0us)
Acquisition line time
The minimum time between 2 lines.
(Default value: 0us)
Table 5-4 Factors affecting line(frame) period
Refer to the frame rate calculator (Ref 6) for the actual line period and frame period.
The free running trigger generated by an internal timer based on the line(frame) period.
This internal timer trigger is “remembered” so that a new sensor exposure cycle can be
started as soon as the sensor is ready. This is illustrated in Figure 5-12.
