3.10 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. Test images are especially useful for service purposes and for

failure diagnostics. In test mode, the image is generated with a software program and the cam-

era's digital devices and does not use the optics, CCD sensor, or ADCs. Four test images are

available.

When using a test image, take the following guidelines into account:

• 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 to output a line on the test image. Multiple transi-

tions of the ExSync signal will produce a two dimensional image as shown in Figure

Figure 3-19.

• If the camera is set for Free-run, each cycle of the camera's internal control signal will trigger

the output of a line on the test image.

• The exposure time has no effect on test images.

You can enable a test image with 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 Mode parameter in the Output Mode

parameters group to enable a test image.

By Setting CSRs

You enable a test image by writing a value to the Mode field of the Test Image Mode CSR (see

page 4-42).
