4.11.2 Status Information

Status information is inserted in the 4 LSB in the last 3D data row (see bits labeled STAT in Fig.
4.9). LSB are transmitted first (see Table 4.11). The status information is divided in fields of 32
bits each, where every information field corresponds to one information parameter (see Table
4.12). Unused bits are set to 0.

4.12 3D Test image
A 3D test image which resembles a moving laser line (see Fig. 4.57) can be enabled by the
property PDTestImage_Enable (in category PeakDetector). This can be used for software
debugging.
4.13 2D Test Images
2D 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 frame grabber. 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 that are caused most
often by a defective cable between camera and frame grabber in CameraLink
cameras. In Gigabit Ethernet cameras test images are mostly useful to test the
grabbing software.
The analysis of the test images with a histogram tool gives the correct result at a
resolution of 1024 x 1024 pixels only.
