Test Image Two
As shown in Figure 3-13, test image two consists of lines with several gray scale gradients ranging
from 0 to 255. If the camera is operating at full 782 x 582 resolution when the test images are
generated:
• lines 1, 2, 3, and 4 start with a gray value of 0 for the first pixel,
• lines 5, 6, 7, and 8 start with a gray value of 1 for the first pixel,
• lines 9, 10, 11, and 12 start with a gray value of 2 on the first pixel, and so on.
(If the camera is operating at a lower resolution when the test images are generated, the basic
appearance of the test pattern will be similar to Figure 3-13, but the staring pixel values on each
line will not be as described above.)
The mathematical expression for test image two is:

Test Image Three
Test image three (not shown) is similar to test image one but it is not stationary. The image moves
by 1 pixel from right to left whenever a one-shot, multi-shot or continuous-shot command signal is
sent to the camera.

Test images are an advanced feature and may not be supported by the camera driver
software that you are using to operate your camera.
