3.12.5 Guidelines When Using Test Images

When using a test image, please take the following guidelines into account:
• When a test image is active, the gain, offset, and exposure time have no effect on the image.
• DSNU and PRNU shading correction produce distortion in the test image. Disable DSNU and
PRNU shading correction before you enable a test image.
• Digital shift makes test images appear very light. Disable digital shift when a test image is
active.
• Use of the area of interest feature will effect the appearance of test images.
• If the camera is set for an exposure mode that uses an ExSync signal, the ExSync signal
must be present and must toggle in order for the camera to output test images. 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.

3.12.6 Enabling/Disabling Test Images

You can enable/disable a test image by using the Camera Configuration Tool Plus (CCT+) or by
using binary write commands from within your own application to set the camera's control and
status registers (CSRs).
With the CCT+
With the CCT+ (see Section 4.1), you use the Test Image setting in the Output parameter group
