11.13 Test Patterns

All cameras include the ability to generate test patterns. Test patterns are used to check the
camera's basic functionality and its ability to transmit an image.
Test patterns can be used for service purposes and for failure diagnostics.
Enabling a Test Pattern
The TestPattern parameter is used to set the camera to output a test pattern. You can set the value
of the TestPattern parameter to one of the test patterns or to Off.
You can set the TestPattern parameter from within your application software by using the Basler
pylon API. The following code snippets illustrate using the API to set the parameter:
// Set for no test pattern
camera.TestPattern.SetValue(TestPattern_Off);
// Set for the first test pattern
camera.TestPattern.SetValue(TestPattern_GreyDiagonalSawtooth8);
// Set for the second test pattern
camera.TestPattern.SetValue(TestPattern_ColorDiagonalSawtooth8);
Test Pattern 1: Gray Diagonal Sawtooth (8 bit)
Fig. 53: Test Pattern 1
The test pattern "Gray Diagonal Sawtooth" (8 bit) is best suited for use when the camera is set for
monochrome 8-bit output. The test pattern consists of fixed diagonal gray gradients ranging from 0
to 255.
If the camera is set for 8-bit output and is operating at full resolution, test pattern 1 will look similar
to Figure 53.
