Standard Features AW00097603000246 Basler aviator GigE10.16 Test ImagesAll cameras include the ability to generate test images. Test images are used to check the camera’sbasic functionality and its ability to transmit an image to the host PC. Test images can be used forservice purposes and for failure diagnostics. For test images, the image is generated internally bythe camera’s logic and does not use the optics, the imaging sensor, or the ADCs. Five test imagesare available (for color cameras six test images).The Effect of Camera Settings on Test ImagesWhen any of the test image is active, the camera’s analog features such as gain, black level, andexposure time have no effect on the images transmitted by the camera. For test images 1, 2, 3, and6 the camera’s digital features, such as the luminance lookup table, will also have no effect on thetransmitted images. But for test images 4 and 5, the cameras digital features will affect the imagestransmitted by the camera. This makes test images 4 and 5 a good way to check the effect of usinga digital feature such as the luminance lookup table.Enabling a Test ImageWith Basler pylon, the Test Image Selector is used to set the camera to output a test image. Youcan set the value of the Test Image Selector to enable one of the test images or to "test image off".You can use the pylon API to set the Test Image Selector from within your application software. Thefollowing code snippets illustrate using the API to set the selector:// Set for no test imageCamera.TestImageSelector.SetValue( TestImageSelector_Off );// Set for test image 1Camera.TestImageSelector.SetValue( TestImageSelector_Testimage1 );You can also use the Basler pylon Viewer application to easily set the parameters.For more information about the pylon API and the pylon Viewer, see Section 3 on page 21.
