Synchronous Exposure Alignment
Exposure is synchronous to the internal timing of the sensor. The readout is concurrent to the
exposure for the fastest possible frame rate.
When a valid trigger is received and the Exposure Time is shorter than the readout period, the
Exposure Start event is latched in the previous frame’s readout. That is; the Exposure Start Event
is delayed and is initiated when the actual exposure starts such that the exposure ends and
readout begins as soon as the previous readout has completed.
• The programmable exposure duration is in 1µs steps.
• Exposure duration is from a camera sensor specific minimum (in µs) up to 16 sec.
•
Any trigger received before the start of frame readout is ignored and generates an invalid frame
trigger event.
Reset Exposure Alignment
Sensor timing is reset to initiate exposure when a valid trigger is received. Readout is sequential to
exposure, reducing the maximum achievable frame rates. That is, a trigger received during
exposure or readout is ignored since data would be lost by performing a reset.
