Secure image signature (SIS)

Definition Secure image signature (SIS) is the synonym for data, which is inserted into an

image to improve or check image integrity.

With the new firmware V3.03, all CCD Marlin models can insert

• Time stamp (1394 bus cycle time at the beginning of integration)

• Frame counter (frames read out of the sensor)

• Trigger counter (external trigger seen only)

into a selectable line position within the image. Time stamp, frame counter and

trigger counter are available as advanced registers to be read out directly.
