Test Images - Basler A500k User Manual

3.11 Test Images

The test image mode is used to check the camera's basic functionality and its ability to transmit
an image via the video data cable. The test image can be used for service purposes and for failure
diagnostics. In test mode, the image is generated with a software program and the camera's digital
devices and does not use the optics, CMOS sensor, or ADCs.
You can put the camera in test image mode using either the Camera Configuration Tool Plus (see
section 4.1) or set the Test Image Command register (see section 4.2.5) using binary commands.

When one of the test images is active, the gain, offset and exposure time have no
effect on the image.
There are three test images:
• a gray scale test image
• a running line test image
• a white screen test image
If the camera is set for an exposure mode that uses an ExSync signal, an ExSync signal is
required to output the test image. If the camera is set for free-run, each cycle of the camera's
internal sync signal will trigger the output of a test image.
