6 Smart Features and the Smart
Features Framework
6.1 What are Smart Features
Smart features are features unique to Basler cameras. Test Images, the Cycle Time Stamp, and
the CRC Checksum are examples of Basler smart features.
In some cases, enabling a smart feature will simply change the behavior of the camera. The Test
Image feature is a good example of this type of smart feature. When the Test Image feature is
enabled, the camera outputs a test image rather than a captured image.
When certain smart features are enabled, the camera actually develops some sort of information
about each image that it acquires. In these cases, the information is added to each image as
trailing data when the image is transmitted from the camera. Examples of this type of smart feature
are the Cycle Time Stamp feature and the CRC Checksum. When the Cycle Time Stamp feature
is enabled, after an image is captured, the camera determines when the acquisition occurred and
develops a cycle time stamp for the image. And if the CRC Checksum feature is enabled, the
camera calculates a checksum for the image. The cycle time stamp and checksum are added as
trailing data to each image as the image is transmitted from the camera.
6.2 What is the Smart Features Framework
The first component of the Smart Features Framework (SFF) is a mechanism that allows you to
enable and to parametrize smart features. This mechanism is essentially an extension of the
register structure defined in the DCAM specification for use with “Advanced Features.” The SFF
establishes a register for each smart feature. By setting bits within the register for a particular
smart feature, you can enable the feature and control how the feature operates.
When certain smart features are enabled, the camera actually develops some sort of data about
each image that it acquires. For example, when the Cycle Time Stamp feature is enabled, the
camera creates a time stamp for each image based on when the image exposure started. In the
cases where a smart feature develops some sort of data about a captured image, the smart
feature’s data is added as trailing data to each image as the image is transmitted from the camera.
The SFF provides a mechanism for parsing the smart features data added to images transmitted
out of the camera by assigning a unique identifier (GUID) to each smart feature. Whenever the
camera adds data for a smart feature to an image, it includes the GUID for the smart feature as
