19.3 Working with triggers
There are several use cases concerning trigger:
19.3.1 Using external trigger with CMOS sensors
19.3.1.1 Scenario
The CMOS sensors used in mvBlueFOX cameras support the following trigger modes:
• Continuous
• OnDemand (software trigger)
• OnLowLevel
• OnHighLevel
• OnHighExpose (only with mvBlueFOX-[Model]205 (5.0 Mpix [2592 x 1944]) (p. 244))
If an external trigger signal occurs (e.g. high), the sensor will start to expose and readout one image. Now, if the
trigger signal is still high, the sensor will start to expose and readout the next image (see Figure 1, upper part). This
will lead to an acquisition just like using continuous trigger.
