3.9 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. In test mode, the image is generated with a software program
and the camera’s digital devices and does not use the optics, CCD sensor, VGCs or ADCs. The
test image can be used for service purposes and for failure diagnostics. Six types of test image
are available.
You can put the camera in test image mode using either the Camera Configuration Tool Plus (see
Section
4.1 ) or binary commands (see Section 4.2 ).
With the Camera Configuration Tool Plus, you use the Test Image setting in the Output parameters
group to set the test image.
With binary commands, you use the Test Image command (see Section 4.2.5 ).
3.9.1 Test Image One
(Gray Gradient)
Test image one is formed with repeated
gray scale gradients ranging from 0 to 255
(8-bit mode) or 0 to 1023 (10-bit mode).
The first pixel in each line has a red value
of 0, a green value of 0 and a blue value of
0. The second pixel has a red value of 1, a
green value of 1, and a blue value of 1, and
so on.
If the camera is set for an exposure mode
that uses an ExSync signal, an ExSync sig-
nal is required to output a line on the test
image. Multiple transitions of the ExSync
signal will produce a two dimensional im-
age as shown in Figure 3-24.
If the camera is set for free-run, each cycle
of the camera’s internal sync signal will trig-
ger the output of a test image.
