8.10 Test Images

All cameras include the ability to generate test images. Test images are used to check the camera’s

basic functionality and its ability to transmit an image to the host PC. Test images can be used for

service purposes and for failure diagnostics.

When the camera is in test image mode, the optics and the imaging sensor are not used. The lines

that make up each test image are generated internally by the camera’s logic and are transmitted to

the host PC line by line.

The Effect of Camera Settings on Test Images

When any test image is active, the camera’s analog features such as analog gain, black level, and

exposure time have no effect on the images transmitted by the camera. For test images 1, 2, and

3, the camera’s digital features, will also have no effect on the transmitted images. But for test

images 4 and 5, the cameras digital features will affect the images transmitted by the camera.

Make sure to disable shading correction before generating test images.

Enabling a Test Image Using Basler pylon

The Test Image Selector is used to set the camera to output a test image. You can set the value of

the Test Image Selector to one of the test images or to "test image off".

You can set the Test Image Selector from within your application software by using the pylon API.

The following code snippets illustrate using the API to set the selector:

// set for no test image

Camera.TestImageSelector.SetValue( TestImageSelector_Off );

// set for the first test image

Camera.TestImageSelector.SetValue( TestImageSelector_Testimage1 );

For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide

and API Reference.

You can also use the Basler pylon Viewer application to easily set the parameters.

For more information about the pylon Viewer, see Section 3.1 on page 15.

If the camera is set to use an electrical signal applied to input line CC1, CC2, CC3

or CC4 as the source signal for the line trigger, these signals must be provided to

the camera in order to generate test images.
