Triggered Mode With Overlap - XIMEA xiQ series Technical Manual

t = t + t
trig_min exp
Example for MQ013MG-E2, Exposure time = 500µs, image = 500 pixels width x 200 pixels height:
t = 29µs + 500µs + 400µs + 16.6µs * 200lines = 4.249µs

Triggered mode with overlap

Several sensors are capable to trigger exposure in overlap mode, so it is capable to reach the same frame rate as in free run
mode.
When the trigger period is longer than the exposure and readout time, the signal wave form will look similar to Triggered mode
without overlap. However when the trigger period is decreased, the sensor will expose the images in overlap mode. In this case,
the frame active signal will be constantly active.
