Internal Test Pattern Generator
The Calibir Series cameras include a number of internal test patterns which can easily confirm if
camera installations are setup correctly.
The internal test patterns are generated by the camera FPGA.
Calibir Test Patterns:
•
Horizontal ramp: Image is filled horizontally with an image that goes from the darkest
possible value to the brightest.
Figure 17: Horizontal Ramp Test Pattern
•
Vertical ramp: Image is filled vertically with an image that goes from the darkest possible
value to the brightest.

• Diagonal ramp: combination of the 2 previous schemes.

• Constant: All pixels in image stay at a defined value.
•
Constant, Incrementing: All pixels in image increment by 1 between successive frames,
going from darkest possible value to the brightest.
• Constant, Incrementing, Fast: All pixels in image increment by 1 between successive
frames, going from darkest possible value to the brightest at a higher frame rate.
•
Vertical Stripes: Pixels alternate along the x-axis between the darkest possible value to the
brightest.
