42 • Operational Reference Genie Monochrome Series-GigE Vision Camera
Binning Control via Sapera LT or GenICam Applications
Sapera
Genie Sapera parameters for Binning:
BinningHorizontal = {Disabled = 1, 2 pixels = 2}
BinningVertical = {Disabled = 1, 2 lines = 2}
In CamExpert, these parameters are available under the “Sensor” tab.
See "
Accessing Features with Sapera++ LT" on page 68.
GenICam features for Binning:
BinningHorizontal = Number of horizontally binned cells (1 = no binning)
BinningVertical = Number of vertically binned cells (1 = no binning)
Trigger Modes
Genie image exposures are initiated by an event. The trigger event is either the camera's programmable internal
clock used in free running mode, an external input used for synchronizing exposures to external triggers, or a
programmed function call message by the controlling computer. These triggering modes are described below.
• Free running (trigger disabled): The Genie free-running mode has a programmable internal timer for frame
rate and a programmable exposure period. Frame rate is 0.1 fps to the maximum supported by the sensor.
Exposures range from 100 µs to a maximum also dependent on the current frame rate. This always uses
Synchronous mode where exposure is aligned to the sensor horizontal line timing.
• External trigger: Exposures are controlled by an external trigger signal. External signals are isolated by an
opto-coupler input with a time programmable debounce circuit. See "
General Inputs" on page 49. The
following section provides information on external trigger timing.
• Software trigger: An exposure trigger is sent as a control command via the Ethernet network connection.
Software triggers can not be considered time accurate due to network latency and sequential command jitter.
But a software trigger is more responsive than calling a single-frame acquisition (Snap command) since the
latter must validate the acquisition parameters and modify on-board buffer allocation if the buffer size has
changed since the last acquisition.
