11.7 Test Images

Test images are generated in the camera FPGA, independent of the image sensor. They can be
used to check the transmission path from the camera to the acquisition software. Independent
from the configured grey level resolution, every possible grey level appears the same number
of times in a test image. Therefore, the histogram of the received image must be flat.
A test image is a useful tool to find data transmission errors or errors in the access
of the image buffers by the acquisition software.
The analysis of the test images with a histogram tool gives a flat histogram only
if the image width is a multiple of 256 (in 8 bit mode).
