3.2.3 Software Activation of Black Reference
The iXM-GS120 camera can perform a black reference sequence through iX Capture, the Phase One SDK, or the Flight Management
System.
The following table describes the black reference mode to use for your capture flow.
This mode uses a prerecorded black reference created during iXM-GS120 production. As a
result, there is no delay in capture flow and the black reference is used for each capture.
This mode takes a black reference one time only. This mode is usually selected for normal
captures in where there are no large changes to exposure time, ISO, or temperature.
Phase One recommends that you initiate a new black reference sequence whenever
possible (for example, during flight while turning the aircraft).
This mode takes a new black reference for every capture.
This slows the capture cycle (approximately twice as slow) but does provide an
accurate, custom black reference for each capture.
The camera uses an internal algorithm to decide when a new black reference is required,
based on specific values of exposure, ISO, or large changes in temperature.
