Parameter Description
Pixel Format For the Genie Color series, the image buffer format is
Bayer Raw8 or Bayer Raw10 or RGB 32-bit or UYVY or YUY2.
Width (in Pixels) Displays the image buffer width (X axis), in pixels.
Height (in Pixels) Displays the image buffer height (Y axis), in pixels.
OffsetX (in Pixels) Specifies the offset in X, from the left of the image, when using an ROI. The image buffer
width is automatically adjusted to compensate for this offset.
OffsetY (in Lines) Specifies the offset in Y, from the top of the image, when using an ROI. The image buffer
height is automatically adjusted to compensate for this offset.
Image Flip Enables hardware based horizontal image flip.
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 the sensor minimum 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 51 . 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.
