TEST IMAGE PATTERNS
2.15.1Test Image patterns
The camera can output several test images, which can be used to verify the camera’s
general performance and connectivity to the frame grabber. This ensures that all the
major modules in the hardware are working properly and that the connection
between the frame grabber and the camera is synchronized – i.e., the image framing,
output mode, communication rate, etc. are properly configured. Please note that the
test image patterns do not exercise and verify the image sensor functionality.
