Trigger Mode
In Trigger mode, See3CAM_CU51 camera is capable of synchronizing the exposure (or
integration) of the pixels of the camera to an external trigger pulse that can be given
through the connector of the camera. Also the duration of the exposure depends on the
pulse duration of the trigger pulse. Since this is a global shutter camera, all the pixels start
and stop integrating at the same time, avoiding rolling skew during the capture of fast
moving scenes. In addition to this, the start of integration of pixels can be synchronized to
an external event in Trigger mode.
In Trigger mode of See3CAM_CU51, the preview will not be available and the camera
will be kept in standby waiting for a trigger pulse to start the integration of pixels and
provide a global shutter image. The user can switch to trigger mode by clicking on the
Trigger Mode
button in the
Extension Settings
tab of the QtCAM application.
The user can configure the camera settings such as exposure, still image resolution, still
image storage location etc., in Master mode and then enter the Trigger mode. In the
Trigger mode, the camera settings will be retained, but preview will not be available. The
camera shall be waiting for an external event on the connector and the camera will start
exposing on the trigger signal. The external trigger pulse on the connector must have a
pulse duration equal to that of the required exposure, so the camera will expose for this
duration and immediately readout the image.
In Trigger mode, only external Trigger event is supported and no software still image
capture is possible.
