Free-running Programmable Exposure Timing
External Trigger Programmable Exposure
•
Also known as “Edge Pre-select” exposure. See the timing diagram below.
•
The external trigger edge initiates the exposure process. The active external trigger edge
can be selected as either the low-high or high-low transition.
•
The delay from active trigger edge to start of exposure is programmable from 1μs to 16
seconds (1μs steps) .
•
Exposure duration is programmable from the sensor minimum (see Genie Sensor
Overview) to 16 seconds (1μs steps).
•
Supports "Synchronous Mode" on page 56 timing for fastest possible frame rates. Start
of exposure is aligned on the next horizontal line while exposure duration granularity is
1µs. Exposure and sensor readout can be concurrent.
•
Supports "Reset Mode" on page 57 timing. Exposure granularity is 1µs. Exposure and
sensor readout must be sequential, limiting the maximal frame rate.
•
Any external trigger received before the previous exposure is complete is ignored. An
application can elect to receive messages about ignored triggers. See "Events" on page
76.
