Genie supports two types of sensor synchronization used to align the exposure to sensor timing: 
•  Synchronous Mode: Exposure is synchronous to the line timing of the sensor. Exposure granularity is 1µs and 

the readout can be concurrent to the exposure for the fastest possible frame rate.  

•  Reset Mode: Timing is reset to initiate exposure of next frame. Exposure granularity is 1µs, but readout must 

be sequential to exposure, reducing the maximum achievable frame rate. 

 

•  Synchronous mode starts the exposure period aligned to the sensor horizontal line timing and the programmable 

duration granularity is 1µs.  

•  In the case of the Genie M640, a horizontal line occurs every 31.77µs. 
•  Exposure duration is from a minimum of 100µs up to 4 sec. 
•  In this mode, sensor exposure and sensor readout of the previous frame's exposure occur simultaneously. This 

allows operating the sensor up to its maximum frame rate. 

•  Any trigger received before the end of the exposure is ignored. The application can elect to receive messages 

about ignored triggers. See 

"

. 

•  Since the external trigger is asynchronous with the Genie horizontal line timing, the frame exposure start is 

subject to 1 horizontal line jitter.
