Operational Reference Nano Series GigE Vision Camera
Internal Programmable Exposure (ExposureMode = Timed)
The Genie Nano in Internal Programmable Timed Exposure mode has the following features:
•
Programmable internal trigger, where the maximum and minimum sensor frame rate limits are
defined by the ExposureTime feature.
•
Exposure synchronization timing is Synchronous Mode where the exposure is aligned with the
sensor horizontal line timing and the next acquisition is triggered by an internal programmable
timer.
•
Exposure duration is user programmable
• Exposure maximum is dependent on the frame rate.
•
Minimum exposure (in µs) is model dependent.
•
Image readout is simultaneous where the grabbed image frame is readout during the next
frame exposure time. This allows for fastest possible frame rates.

Exposure Example
Free-running Exposure Timing
External Trigger: Programmable Exposure
• Also known as “Edge Pre-select” exposure. See timing diagram below.
•
An external trigger edge initiates the exposure process.
•
The user programmable delay (exposureDelay) from valid trigger edge to start of exposure is
camera model specific.
•
Supports Synchronous Mode timing for fastest possible frame rates. Start of exposure is aligned
on the next horizontal line while the exposure duration period is in 1µs steps. Exposure and
sensor readout can be concurrent.
•
Exposure duration is programmable from the model dependent minimum to 16 seconds (in 1μs
steps).
