3.11.3 Test Image One (Fixed Gray Gradient)
Test image one is formed with a vertical gra-
dient that ranges from 0 to 255 and repeats
every 256 pixels as shown in Figure 3-29.
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. The
third pixel has a red value of 2, a green
value of 2 and a blue value of 2, and so on.
Test image one is useful for checking the in-
tegrity of the data transmitted by the cam-
era. If you capture lines and examine the
pixel values in the captured lines, the values
should be exactly as described above.

The description of the pixel values in test image one is only valid when the camera
is set for 8 bit output. If the camera is set for 10 bit output, the gradients range from
0 to 1023 and repeat every 1024 pixels.
