136 Basler sprint Mono Cameras
6.5 Line Stamp
The line stamp feature provides you with information about each acquired line such as the line
counter value, the sum of the pixel values in the line, and the contrast value of the line. When the
line stamp feature is enabled, 16 extra "stamp pixel" values are added to the end of each
transmitted line as shown in Figure 47. As an example, the figure illustrates stamp pixels when a
camera with 4096 pixels per line is set for a 2 tap video data output mode and edge or level
controlled exposure.
Each stamp pixel carries an 8, 10, or 12 bit value that conveys information about the transmitted
line.

Note
When the camera is operating in an 8 bit output mode, the stamp pixels will be
8 bit values.
When the camera is operating in a 10 bit output mode, the stamp pixels will be
10 bit values but only the 8 MSBs will carry information. The 2 LSBs will be
packed with zeros.
When the camera is operating in a 12 bit output mode, the stamp pixels will be
12 bit values but only the 8 MSBs will carry information. The 4 LSBs will be
packed with zeros.
