STINGRAY Technical Manual V4.4.4

Assuming camera runs in continuous mode, the check of monotonically
changing bus cycle time is a simple test that no image was skipped or
lost in the camera or subsequently in the image processing chain.

In (synchronized) multi-camera applications, SIS can be used to iden-
tify those images, shot at the same moment in time.

The cross-check of the frame counter of the camera against the frame
counter of the host system also identifies any skipped or lost images
during transmission.

The cross-check of the trigger counter against the frame counter in the
camera can identify a trigger overrun in the camera.

AOI can be inserted in the image if it was set as a variable e.g. in a
sequence.

Exposure/gain scenario parameters can be inserted in the image if set
as a variable in e.g. sequence mode to identify the imaging conditions.

Inserting input and output state on exposure start can be helpful when
working with input and output signals.

Index of sequence mode is inserted automatically if SIS is used together
with sequence mode.

Serial number inserted in the image helps to document/identify the
camera in e.g. multi-camera applications.

Note

FirePackage offers additional and independent checks
to be performed for the purpose of image integrity.
Details can be found in the respective documentation.
