Test Image Two

As shown in Figure 6-4, test image two consists of rows with several gray scale gradients ranging

from 0 to 255. Assuming that the camera is operating at full 656 x 491 resolution and is set for a

monochrome, 8 bit output mode, when the test images are generated:

• rows 0, 1, and 2 start with a gray value of 0 for the first pixel,

• rows 3, 4, 5, and 6 start with a gray value of 1 for the first pixel,

• rows 7, 8, 9, and 10 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 6-4, but the staring pixel values on each

row will not be as described above.)

The mathematical expression for test image two is:

Test Image Three

Test image three 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 or a continuous-shot command signal is sent to the camera.
